ANNOUNCER: This program is about unsolved mysteries.

Whenever possible, the actual family members

and police officials have participated

in recreating the events.

What you are about to see is not a news broadcast.

ROBERT STACK (VOICEOVER): This man

calls himself Jose Antonio Gonzalez,

but that is a known alias.

He is a convicted bank robber and a man without a past.

Since his arrest in 1990, Gonzalez

has refused to reveal his true identity or any other detail

about his shadowy life.

On June 30, 1991, Larry Williams walked into his son's house

and into a nightmare.

Danny Williams was dead from a single bullet

wound to his forehead, at first glance an obvious suicide.

But Larry Williams has collected convincing

evidence that indicates his son may have been murdered.

In 1978, a young pilot named Frederick

Valentich took off from Moorabbin Airport in Australia.

47 minutes later, a frantic Valentich radioed that he had

encountered a bizarre source.

Then the radio transmissions abruptly ceased

and the plane vanished, as if plucked from the sky.

Join me for another edition of "Unsolved Mysteries."

[theme music]

ROBERT STACK (VOICEOVER): Anchorage,

Alaska, December 11th, 1990.

At 3:00 PM, two bank employees arrived at a local mall

to restock an automated teller machine.

The security guard took the cash into a small secluded room

behind the machine while the teller went

outside to reprogram the ATM.

Open the door.

Don't turn around.

Do exactly what I say and you won't be hurt.

Do you understand? - Yes.

Open the door.

[knocking]

Put your hands above your head.

Into the room.

You, over here.

You, open the vault. Turn around.

There was nothing about this robbery that

could have happened that this individual

wasn't prepared to handle.

He knew the entrance into this back room, back hallway

in order to get into the teller machine.

He knew that no one could see him from there.

Put the money in the bag.

Put your hands behind your back.

DAVID E. HELLER: And he knew exactly what it took in order

to open up the machine where the money was stored

inside a machine and also instructed the teller to take

a videotape out of the video machine

so as not to be caught on film.

Get the surveillance tape now.

The robber also had a small smile

on his face, which the guard thought was a little peculiar.

The guard believed that this robber was very relaxed.

I know what your name is, I know where you live.

Do you understand?

Yes.

Both of you, silent for five minutes.

ROBERT STACK (VOICEOVER): The FBI

believed the robbery was an inside job,

even though the two employees had

not recognized their assailant.

Suspicion immediately fell on a former security guard named

Jose Antonio Gonzalez, who was already

being investigated in connection with a similar robbery.

But Gonzalez had conveniently disappeared.

Two days later in Redmond, Washington, 1,500 miles south

of Anchorage, a postal worker noticed

a partially opened package.

Oh, wait a minute.

This one's torn.

Wait a minute.

Looks like a gun in there.

The address that was on the top of the box

was an address to a gentleman named Jose Antonio Gonzalez

in Redmond, Washington.

The return address was Anchorage, Alaska.

ROBERT STACK (VOICEOVER): A second box

was later found in the same shipment, also addressed

to Jose Antonio Gonzalez.

Postal inspectors obtained a warrant to search both boxes

and discovered a small arsenal.

38, loaded.

Look at this, Glock--

loaded, as well.

Beretta, loaded.

And what do we have here?

Money.

ROBERT STACK (VOICEOVER): The postal inspectors also found

cash, $65,540, the exact amount taken

in the Anchorage ATM heist.

Make sure he gets an AG-49 and we'll just wait for him.

ROBERT STACK (VOICEOVER): Postal inspectors

set up what they call a controlled delivery,

in essence a sting operation.

On December 14, 1990, just three days after the robbery,

Jose Gonzalez stepped right into their trap.

OK.

Thank you very much.

Gonzalez, hands in the air.

Postal inspectors.

Back away from the car.

What's going on?

Back away from the car.

Get down on your knees.

ROBERT STACK (VOICEOVER): Gonzalez

was charged with armed bank robbery and four

counts of illegal transportation of a firearm using the US Mail.

Once in custody, Gonzalez was cooperative,

perhaps too cooperative.

Without prompting, he told authorities his life's story.

Born in Puerto Rico, graduated from Knickerbocker

High School in New York City, attended

West Virginia University.

Gonzalez then rattled off his social security

number, his date of birth, and other vital statistics.

Thank you.

Fingerprints over here.

This man was almost too good with his background.

Everything was right there on the tip of his tongue,

from where he went to high school

to where he was brought up.

ROBERT STACK (VOICEOVER): Unfortunately,

nothing Gonzalez said was true.

There was no Knickerbocker High School and no one

named Jose Antonio Gonzalez had ever attended

West Virginia University.

His social security number did seem legitimate until the FBI

discovered he and two of them.

One belonged to a boy who was 11 years old.

It was clearly fraudulent.

But the other had been issued know say

Antonio Gonzalez born in 1952.

Maybe later.

Where were you born?

Puerto Rico.

So we located a birth certificate

in Puerto Rico under the name that he said

he is, Jose Antonio Gonzalez.

But then 11 days later, after the birth of Jose Antonio

Gonzalez, that child died of tetanus

and we have the death certificate.

So we know who he is not, we don't know who he is.

When did you come to the United States?

ROBERT STACK (VOICEOVER): Under interrogation,

Gonzalez continued to embroider the facts.

His already elaborate background became more and more exotic.

Ever been in the service?

Yes, I have.

What branch?

French Foreign Legion.

French Foreign Legion?

Yes.

GORDON D. BITTNER: Mr. Gonzales indicated

that he was a former French Foreign Legionnaire, that he'd

been in the Legion for approximately five years,

that he'd seen action in Chad and Beirut.

He claimed to be a martial arts expert and an expert

with various types of weapons.

ROBERT STACK (VOICEOVER): Gonzalez was full of surprises.

While he was awaiting trial, the authorities

discovered that he was fluent that at least

four different languages.

[speaking foreign language]

GORDON D. BITTNER: Here we have an individual who speaks,

apparently writes, and is very functional in English,

Spanish, French, and some type of Croatian dialect.

He conversed with these people freely, very easily.

The man was not your run of the mill bank robber.

The more we kept digging into this gentleman's background,

the more mystery surrounded him.

On October 15th, 1992, the enigmatic Mr. Gonzalez

was convicted of armed bank robbery

and sent to the Sheridan federal Penitentiary in Oregon.

But even with Gonzalez safely behind bars,

the case continued to fascinate investigators.

The only possible key to the prisoner's true identity

lay with two mysterious women, both of whom

vanished before they could be questioned.

Hi. Can I help you?

Yes.

I'm here to pick up the car for Jose Gonzales.

ROBERT STACK (VOICEOVER): After Gonzalez was arrested,

his car was impounded by the Redmond Police.

The next day, a woman showed up to claim it.

--from his attorney.

I don't understand.

He asked me to come and pick up his car.

Is there a problem?

Yes, ma'am.

I need what's called an authorization for release

and you can get that from his attorney.

I cannot get the car at all without the authorization?

No, you can't.

ROBERT STACK (VOICEOVER): According to the police,

the woman was an intimate acquaintance and possibly

an accomplice of Gonzalez.

She went by the name Nadine Castel

and had known Gonzalez for at least three years

before he went to prison.

GORDON D. BITTNER: She has always

been around Mr. Gonzalez.

At times, she has introduced Mr. Gonzales as a brother,

as a lover, and as a friend.

She's never worked that we can find.

Always drove very expensive cars, always dressed

in very expensive clothes.

Nadine appears to be the person who

arranges for and acquires identification

for Mr. Gonzalez.

She's always there, almost like somebody

that looks over him and has the documentation

that he would need.

She has disappeared, absolutely disappeared, as far as we

know, in the United States.

ROBERT STACK (VOICEOVER): Nadine Castel

is five feet, five inches tall, weighs around 125 pounds,

and has dark hair and eyes.

She is a French national who has lived in London

and the United States.

She sometimes uses the last names of Gautam and Cartel.

Another woman who police believe might also be an accomplice

has been positively identified.

Brenda Penninger was Gonzalez's girlfriend

at the time of the robbery.

A few days after Nadine's unsuccessful attempt to pick up

the car, Brenda Penninger showed up at the impound lot

with all the right papers.

The FBI, anticipating her arrival,

had asked the impound lot attendant to serve

server with a subpoena.

Is that Brenda Penninger?

That's right.

I've been asked to give this to you.

Sure.

What is it?

That's a subpoena so you'll come before the grand jury.

ROBERT STACK (VOICEOVER): Incredibly, just three days

later, the car would be found 2,400

miles away in a parking lot at the Newark, New Jersey airport.

We have to this day never located Miss Penninger.

We've talked to her mother, we've talked to everyone

that we knew that had contact with her,

and there has been no contact that we

can verify since that day three days

after she picked up the car.

She's gone.

We don't know where she's at and we don't know her fate.

ROBERT STACK (VOICEOVER): Brenda Penninger

is five feet, nine inches tall, weighs 145 pounds,

and has blond hair and blue eyes.

Update-- the mystery robber has been identified,

thanks in part to a viewer tip.

His name is Milorad Zivkovic, a 27-year-old

Yugoslavian national who was apparently born in France.

After the broadcast, authorities also located and questioned

Zivkovic's two female friends.

Neither has been charged with any wrongdoing in this case.

As for the mysterious Zivkovic, investigators

are still hoping to discover more about his shadowy past.

Next, the dramatic account of a young pilot's

close encounter of the most mysterious kind.

October 21st, 1978, 6:19 PM, the continent of Australia.

A single-engine Cessna 182 lifted off from Robin Airport

just south of Melbourne.

The pilot was 20-year-old Frederick Valentich.

Valentich had been flying for two years,

accumulating more than 150 hours of solo time.

He had dreams of one day becoming

a commercial airline pilot.

Valentich's flight plan called for a 40-minute trip west

along the Australian coast.

At Cape Otway, he would head south

for a half hour run over Bass Strait to King Island.

It was a route he had followed on several occasions.

But this flight would be anything but routine.

KEN LLEWELYN: It was a fairly normal exercise.

He had an appropriate instrument rating for the trip.

It was a very straightforward flight.

And I mean, I could see no reason why it shouldn't have

been concluded successfully.

What happened three quarters of an hour into that flight

I think will be one of the great mysteries

of Australian aviation.

Melbourne, this is Delta Sierra Juliet.

Is there any known traffic below 5,000?

Delta Sierra Juliet, no known traffic.

Delta Sierra Juliet, there seems to be

a large aircraft below 5,000.

ROBERT STACK (VOICEOVER): At just over halfway

through his flight, Valentich had

been in contact with the flight service center on the ground.

Evidence mounted that something was not quite right.

The following recreation was based

on the transcript of Valentich's exchange

with an air traffic controller.

It seems to me like some sort of landing lights.

As it gets closer, it's--

could be one or two lights, I don't know.

Melbourne, this is Delta Sierra Juliet.

That aircraft's just passed over me at least 1,000 feet above.

Roger and it is a large aircraft, confirm?

Unknown due to the speed at which it was traveling.

Is there any Air Force aircraft in this vicinity?

Delta Sierra Juliet, no known aircraft in the vicinity.

Delta Sierra Juliet, it seems like he's playing

some sort of game up here.

He's trailing over me at two and three times

at speeds I cannot identify.

Can you describe the aircraft?

Delta Sierra Juliet, as it passes by, it's a long shape.

He wasn't to the point where he was panicking,

but he was genuinely concerned by what he saw,

with what he saw.

He was worried.

He sounded confused.

Then as he described what the aircraft was doing,

I became a little bit concerned, too.

Melbourne, this thing's just stationary.

What I'm doing now is orbiting and this thing

is just orbiting on top of me.

It's got a green light and it's sort of metallic,

like it's shiny all over.

It's just disappeared.

Melbourne, you wouldn't know what sort of aircraft

I've got up here, would you?

Is this some sort of military aircraft or what?

Delta Sierra Juliet, is the aircraft still with you?

Delta Sierra Juliet, now approaching from southwest.

Delta Sierra Juliet, my engine's [inaudible].

I've got is set on 23, 24 and this thing's just coughing.

Delta Sierra Juliet.

Melbourne, this strange aircraft is just

hovering on top of me again.

It's hovering and it's--

it's not an aircraft.

ROBERT STACK (VOICEOVER): Suddenly,

an unidentifiable clicking noise came over the radio.

The sound lasted 17 seconds, then silence.

Delta Sierra Juliet, this is Melbourne.

I had extreme doubt as to his safety.

Flying a single engine airplane over water,

lost communication in such strange circumstances.

I put an alert phase on the airplane,

and once that had elapsed we then

went to the distress phase stage and that was

the commencement of the search.

About 11:30 or midnight, Frederick was not home.

And then we heard on the radio that an aircraft went missing.

And then two policemen call at the door

and they verified that yes, they said that aircraft

presumably was your son.

It's an extended search and we don't

know what's happened to him.

ROBERT STACK (VOICEOVER): For four days,

a flotilla of search vessels crisscrossed Bass Strait.

There was absolutely no sign of Valentich or his aircraft,

no evidence to suggest there had even been a crash.

All that remained was the final baffling radio transmission.

It's hovering and it's not an aircraft,

these were Frederick Valentich's final haunting words,

words which inevitably lead to speculation

that the young pilot had encountered a UFO.

However, it was nothing more than speculation

until a witness came forward with

a startling firsthand account.

Around the time of Valentich's disappearance,

the eyewitness and his family were returning

from an afternoon outing when they noticed

unusual activity in the sky.

- Hey, that's a plane. - I can see the plane.

It's the green light above the plane, there.

ROBERT STACK (VOICEOVER): The witness has asked that we

not reveal his identity.

Yeah, there.

EYEWITNESS: I looked up and saw this long green light

about 1,000 to 2,000 feet above the aircraft.

So we sat there and watched it for a few seconds.

Then the green light got closer to the plane.

I said, that plane is coming down pretty steep,

at a 45 degree angle.

I said, I think it's going to crash.

ROBERT STACK (VOICEOVER): The eyewitness account

appeared to support the theory that Valentich

had a run-in with a UFO.

However, the witness did not actually see the aircraft crash

in the Bass Strait.

The only certainty was that Valentich had vanished.

Then six weeks later, an amateur photographer

came forward with evidence that some

believe confirmed the presence of a UFO over Bass Strait.

On the evening of the flight, Roy Manifold

had been setting up to shoot a sunset at Cape Otway,

almost directly under Valentich's flight path.

ROY MANIFOLD: Everything was fine and done the normal thing.

I just had the camera on automatic exposure.

And I took these six photographs of the sun

disappearing into the sea.

ROBERT STACK (VOICEOVER): When developed,

the last of Manifold's photographs

displayed a peculiar blemish.

I observed this mark on the print

that looked like a developing error or something,

like they'd mucked it up.

I said, just a minute.

That was taken-- that night I took

that sunset is exactly the night that this guy disappeared.

ROBERT STACK (VOICEOVER): A leading Australian photo lab

found neither dirt nor damage on the negative,

determining that the strange mark

was actually in the picture.

The film was later sent to the United States

for computer analysis by a team of UFO researchers.

They claimed that the blot was actually

a solid metallic object.

To them, it appeared to be enveloped

in a cloud of exhaust, situated about a mile from the camera.

However, a second, more recent, analysis

concluded that the spot is in all

probability a developing error.

Even so, Roy Manifold is inclined to believe

the photograph does show something of consequence.

ROY MANIFOLD: Unfortunately, I didn't see it

and I didn't hear anything that particular night, either.

First time I've had something on any of my printing I've

had done with thousands of photographs

and without any incidents of any and anything like that on them.

ROBERT STACK (VOICEOVER): Skeptics

tend to dismiss the photograph as just

another far-fetched effort to prove the existence of visitors

from outer space.

But even for those who are not prone to believe in UFOs,

the events of October 21st, 1978 continue to defy explanation.

There's been no recovery of any wreckage.

Of course, he has gone so we're left with an open case which

sounds very much like he did encounter

something very mysterious.

And there's no other conclusion that I

can come to, other than that.

It is hard.

I'm very sentimental on keeping everything

that belonged to him.

Even the motor car that he was driving to the airport I'm

still driving.

And I believe that my son possibly one day

will come back.

And this is a dream that might come true one day.

ROBERT STACK (VOICEOVER): 15 years

have passed as Frederick Valentich

flew off to his uncertain fate.

However, the questions raised by his mysterious disappearance

are just as disturbing today.

What exactly did Valentich see in the minutes

before radio contact was lost?

This thing's just stationary.

ROBERT STACK (VOICEOVER): What was the brilliant green light

seen hovering over the Cessna, and did that same light

somehow overpowered Valentich's plane as it vanished from view?

Perhaps the secret of Frederick Valentich

does lie many fathoms beneath Bass Strait,

or perhaps it lies far from our planet, light years

beyond our understanding.

December 22nd, 1991, Goose Creek, South Carolina.

At 10:30 PM, P A speeding car with three men

inside was pulled over on a desolate road

leading to the local marina.

I approached the vehicle on the driver's side

and said, good evening.

Cold I see your license and registration?

At that point, I got virtually no response.

Can I see your license and registration?

AL BELANGER: I figured maybe he didn't

hear me so I asked him again.

Sir, could I see your license and registration, please?

[speaking spanish]

AL BELANGER: The person in the back seat

said something in a foreign language, which I think

was Spanish.

The driver then responded by reaching across

to the glove box and pulling out what

turned out to be a passport.

Here's your paperwork back, sir.

AL BELANGER: I told him to slow it down, be careful.

I never get any response from him.

He never said, yes or thank you.

The two guys in front seat never spoke a word.

ROBERT STACK (VOICEOVER): The next morning, Officer Belanger

was surprised to learn that the two men in the front seat

of the car he had stopped were supposedly missing at sea,

the focus of an intense month-long search

by the Coast Guard.

The men were French sailors, 37-year-old Yves Emanuel Pain

and 24-year-old Laurent Hernac, hired

to convoy a French-made sailboat to new owners.

In October of 1991, they had embarked on a 2,500-mile

voyage from Annapolis, Maryland to Guadalupe

in the West Indies.

Their vessel was a state of the art Antigua catamaran

worth $200,000.

The boat was perhaps the most sophisticated of its kind,

strapped to the gills with high tech

radar, a satellite tracking unit,

and electronic navigational equipment.

The Antigua's unique construction

made it unsinkable and virtually undetectable to radar,

a perfect vessel for transporting weapons or drugs.

Yves Emmanuel and Laurent planned

to sail down the Chesapeake Bay, around Cape Hatteras,

and parallel to the East Coast of the US

before jumping to their final destination, Guadalupe.

When the Antigua failed to arrive on schedule,

the Coast Guard was notified.

We searched for a little over two weeks.

We also alerted all the cutters and aircraft

who search throughout the Caribbean

every day for other things.

Never saw one sight of the vessel.

It never showed up, they've never seen it sense.

ROBERT STACK (VOICEOVER): However, the Coast Guard

did discover that the Antigua was sighted

a number of times several miles of course

in the Intracoastal Waterway.

The waterway is a protected inland passage

which stretches from New England through Florida.

Nobody can explain what the boat was doing there.

Have you seen this boat or these two guys?

ROBERT STACK (VOICEOVER): In December of 1991,

two of Yves Emmanuel's friends flew

from France to South Carolina to launch their own investigation.

Jean Yves Lallinec and Isabel [inaudible] by retracing

the catamaran's route.

Their first stop was a bridge 90 miles north

of Charleston, South Carolina.

Hi.

Bonjour.

How are you?

How can I help you?

Yes.

We are looking for this French boat that disappeared

along the Waterway in November.

Oh, the Antigua 37.

Sure.

ROBERT STACK (VOICEOVER): The bridge tender remembered

seeing the two missing sailors.

Surprisingly, he also revealed there

was a third man on the boat.

A third person was not supposed to be on board.

The fact that they did not contact the captain--

ROBERT STACK (VOICEOVER): Greg Flynn is a local yachtsman

who helped the search.

--plans or that there was someone else aboard or that

they had any trouble indicates that something happened

that had not been planned for.

ROBERT STACK (VOICEOVER): The mysterious third passenger

was sighted by at least five different witnesses.

Each reported that the man did not seem threatening,

leading to rumors that perhaps one or both of the Frenchmen

had been involved in stealing the boat.

But their families and friends vehemently

dismissed that scenario.

Hey, Laurent, [inaudible].

[speaking french]

INTERPRETER: Truly, Yves Emanuel is not the type of person who

would do something like that.

He was training someone he didn't know beforehand

and felt responsible, both for the boat and for Laurent.

It's impossible that Yves Emanuel would have evolved

Laurent in some dangerous adventure,

even if it meant making enormous sums of money.

ROBERT STACK (VOICEOVER): Jean Yves

is convinced that the stranger, perhaps aided

by an armed hidden accomplice, hijacked the Antigua

but did not know how to sail it.

[speaking french]

INTERPRETER: If the purpose was simply to steal the boat,

they would have just killed Yves Emanuel and Laurent

and thrown them overboard.

There must have been a reason for keeping them alive,

and logically that seems to be just to keep the boat going.

ROBERT STACK (VOICEOVER): Yves Emanuel Pain and Laurent Hernac

were last seen on the boat 30 miles south

of Charleston, South Carolina.

Five weeks later, they were pulled over in a speeding car.

Was the man in the back seat the mysterious third passenger?

Perhaps Emanuel and Laurent were being held against their will,

or perhaps--

though it seems unlikely-- they fooled everyone and made

of with a $200,000 prize.

Next, a father embarks on a desperate quest

to prove to authorities that his son did not commit suicide.

Sunday, June 30, 1991, Galesburg, Illinois.

Longtime residents Larry and Lois Williams

had finally given in to two days of worry.

If he doesn't answer the door, I'm going to go inside.

ROBERT STACK (VOICEOVER): They had been trying

to reach their 23-year-old son, Danny, since early Saturday

morning.

I think I can get in through the kitchen window.

Danny?

This is your dad.

LARRY WILLIAMS: I kept calling Danny's name,

saying, Danny, this is your dad, this me coming in, because he

did have a gun in the house for protection

and I didn't want to be in a situation where he was asleep

and shot his own dad.

My first thought in looking at him is that he was not alive.

He was sitting on the couch in an upright position

with a bullet in his head and a gun in his lap.

So the comment that I made as I went through the door, ooh,

Dan, don't let this be what it looks like.

ROBERT STACK (VOICEOVER): Danny Williams was

Larry and Lois' youngest son.

For two years, Danny had managed distribution

for the family's multimillion dollar

apparel manufacturing company.

He had recently bought his first house, the house where he died.

Larry Williams called the Galesburg Police.

It's a 9mm semi-automatic pistol.

JOHN SCHLAF: The position of the body, the type of wound,

the absence of any specific evidence of foul play

indicated to us that the gunshot wound could have

been self-inflicted and caused us to classify

the case as a suicide.

I grew up in the South handling guns.

I know how guns operate, I've shot every kind that there is.

And it would be almost impossible for an individual

to have shot themselves and have a gun laying in the lap

in a position this was.

It just wasn't natural.

ROBERT STACK (VOICEOVER): Convinced that his son had not

committed suicide, Larry Williams hired

a private detective, Mike Turnquist.

The time of Danny's death had been estimated

to be 2:30 AM on Saturday, but Turnquist immediately

found a neighbor who said she had

seen Danny several hours later, at approximately 10:30 AM.

Good morning, Mrs. Sayrs.

My name is Mike Turnquist.

I'm a private investigator and I'm working

on the death of Danny Williams.

I shouldn't admit it, but I watch everybody's business.

It was Saturday morning that I saw Danny

get in the car with this woman.

So naturally, being nosey as I am, I look her over real good.

She had dark hair.

She would have been between 25 and 30

ROBERT STACK (VOICEOVER): The police

knew that Danny, whose license had been revoked,

was picked up by his mother on Friday, the day before he died.

They believe Mrs. Sayrs had her days mixed up.

DARLENE SAYRS: No, it was not Friday.

It was Saturday.

And the lady in the blue car was too

young to have been his mother.

ROBERT STACK (VOICEOVER): Several witnesses

had also noticed the activity at Danny's house on Sunday,

a full 24 hours after the estimated time of death.

One of the people later seen outside the house

was a young man with curly brown hair, approximately

five feet, four inches tall.

The eyewitness testimony can easily be mistaken,

it's as simple as that.

They may have seen some activity there,

but it's a distinct possibility that the days

may have been confused as to when

they were seeing that movement.

ROBERT STACK (VOICEOVER): Danny's father claims

that some of the physical evidence

was turned up by the police themselves seemed

to argue against suicide.

The bullet which they believe had

killed Danny exited through his head and lodged in the wall.

Curiously, when the police removed the bullet,

there was only one small spot which appeared

to be blood on the paneling.

With the head being that close to the wall,

you most certainly would expect to find

large or massive amounts of blood splatter,

either at or near the back of the couch

and most certainly on the back wall.

We don't necessarily agree that there

would have to be a large quantity of blood behind him.

The theory that there would have to be a large amount of blood

is in some cases based on what's seen in the movies

and in what's seen on television,

and that's not necessarily consistent with what

happens in fact.

ROBERT STACK (VOICEOVER): Larry Williams next brought

in an independent forensic scientist, Mark Boese,

to determine whether someone else had been in the house

when Danny died.

MARK BOESE: I had this feeling that I was going to go out, see

the house, see a typical messy scene,

and tell Larry that I think your son committed suicide.

From the pictures of Danny, it did look like a contact wound

on the forehead.

So I could go with a suicide possibly or an execution.

When we get to the house and there's

a lack of evidence to support the suicide.

Hey, Larry, you better take a look at this.

ROBERT STACK (VOICEOVER): Boese used a laser luminescence

scanner to search out organic matter,

including blood, which might not be apparent to the naked eye.

He discovered evidence of blood in several places,

even on the television set.

Wow.

Take a look at that.

Splatter pattern all over the TV set.

If Danny had just shot himself sitting there,

you definitely would not have a pattern

at all behind the TV set.

And there's nothing in the Danny got up after shooting himself

and walked around, so someone else

obviously dropped the blood droplets

everywhere else that we found.

We'll have to take a swabbing of that,

bring it back to the lab and get it typed.

ROBERT STACK (VOICEOVER): The blood found on and behind

the television is still awaiting tests

by a forensic scientist who specializes

in blood pattern analysis.

However, samples found in other parts of the house

have been typed.

Danny Williams' blood was type B. Mark Boese

found type B and type O blood in the den where Danny's body was.

Oddly, Boese also found type O blood in the bathroom

and inside the pocket of Danny's jeans.

It is not possible that all blood in the room

came from Danny.

It's an impossibility.

This evidence suggests to me that two people in the room

were bleeding, two separate individuals.

ROBERT STACK (VOICEOVER): The official police

positions is that the alleged type O

blood samples had been compromised when

the crime scene was cleaned.

According to the Illinois State Crime Lab,

the adulterated samples could not be typed definitively.

I would begin to question their procedures

if they claim that they did not find

type O blood on the evidence.

I could guarantee you, send that same evidence

to five different independent laboratories that

have no idea what this case is about, that have no idea

that this was a murder or suicide or anything,

and they will come back with type B blood and type O blood.

ROBERT STACK (VOICEOVER): The police

also point out that there was no way

to determine how long the alleged type

O blood had been there.

Further, they say that Mark Boese's samples,

taken six weeks after Danny's death,

were not fresh enough to type.

I don't know why they would argue the point.

King Tut was typed for blood and he's how

many thousands of years old?

The independent lab feels very confident in their results.

They have provided those results to Mr. Williams

and that's contributed to his concerns

about the finding of suicide.

We feel just as strongly about the results of the Illinois

State Crime Lab, that there was no evidence

of a type O blood in that home.

ROBERT STACK (VOICEOVER): Mark Boese's investigation

appeared to turn up a piece of evidence

which had been previously overlooked

and which supported the theory that the blood of two

different people was shed in Danny's house.

It's the same type that Danny's gun would use.

LARRY WILLIAMS: When Mark was processing the room,

he opened the couch up and a shell casing fell out.

Later tests showed that this shell

did come from Danny's gun, it had been recently fired.

So there were two shells found on the couch

that came from Danny.

Now, we tried to analyze and decided,

well, did Danny shoot someone?

Did someone else use Danny's gun and shoot him?

From the scene photos I saw, Danny's gun was laying

on his lap, his hand was laying on top of the gun

just as if he shot and then set it back down.

It's a little inconsistent with a suicide.

OK, Larry.

I set up the rod here in line with the bullet path

through the wall.

Now I'm going to get down and try

to get my head in line with the bullet path and the wall.

How am I doing?

Well, you're low enough, but you've got to point

the gun more toward the wall.

I can't do it.

I can't squeeze off.

The only way I can think of is holding

the weapon in this manner.

OK.

How am I doing? - Yeah.

The line's right. - All right.

And it's through my head and it can be squeezed off.

But you would fall over on the floor.

I would fall over on the floor.

The body would have gone forward.

The body wouldn't have moved back

into the position it was in and the gun probably

would not have been in his lap.

It probably would be on the floor or the coffee table.

Our investigation indicated that the position of the hole

in the wall was consistent with the way the body was found,

primarily based on the fact that we, again,

can't say specifically how the individual was sitting

and exactly where on the couch he was sitting at the time

that the weapon was discharged.

ROBERT STACK (VOICEOVER): Mark Boese

has come to believe that Danny was

probably not shot in the den.

One theory is that there was an altercation somewhere else,

during which Danny's blood and another person's was spilled.

Perhaps that person took Danny's keys out of his pocket,

leaving behind a trace of type O blood.

Finally, the crime scene was arranged to make Danny's death

look like a suicide.

We can advance theories all day long, everyone can.

But the factual data that we've gathered we

feel comfortable with.

Well, he picked up a gun and he--

ROBERT STACK (VOICEOVER): According to the police,

there was one final fact to support the suicide ruling.

They say that Danny Williams' girlfriend described

an argument which had also resulted in a shooting incident

six months before Danny's death.

JOHN SCHLAF: He had placed a weapon, a handgun, to his head.

She then turned and started to leave the room

and heard the weapon discharge and found

that he had discharged the weapon into a wall.

So apparently, he had considered this act

before, he had discussed this act before

and had taken I think what would have to be considered

a substantial step towards that act

by the discharge of the weapon during the argument.

What it appears that's happened

is they have come up with a conclusion

and then they've gone to a great degree of effort

to try to support their theory that they put together.

Had they put as much effort into trying to find out

what the truth was and what happened,

they would be working along the same lines

that the family is today.

Fact.

Danny?

This is your dad.

LARRY WILLIAMS: The investigators, crime labs,

and what have you that I've had working

on this from the beginning, as soon as they went

into the house and saw evidence that was in there

and is still there now, were convinced, as I was,

that it was cold-blooded murder.

ROBERT STACK (VOICEOVER): In this most perplexing case,

one issue has never been addressed.

If Danny Williams was murdered, who killed him and why?

Questions even his father has been unable to answer.

Next week, "Unsolved Mysteries" travels

to Russia to investigate the fascinating mystery

of Anastasia.

She was a beautiful teenage daughter of the last czar

of Russia, Nicolas II.

History holds at the entire imperial family was executed

in the aftermath of the Bolshevik Revolution,

but years later, a woman named Hannah Anderson turned up

in Germany claiming that she was Anastasia

and many believe she had the evidence to prove it.

Her incredible claims sparked a 35-year court battle

for the czar's legacy of $80 million.

Join me next time for this intriguing journey

to turn of the century Russia and more

on "Unsolved Mysteries."
