-Just after dark on a warm summer
evening, five children were walking home along this road.
Suddenly, out of nowhere, a pickup truck
headed towards them.
[honking]
[screaming]
-Three of the children were hit.
One was k*lled.
The driver sped away.
Investigators called on state-of-the-art science
to reconstruct the crime in hopes of learning how
the accident happened and the identity of the driver.
-Fort Lauderdale, Florida, is one
of America's most popular resort towns.
The beach and sunny weather bring
in almost million tourists each year.
And the city is also home to and /
million full-time residents.
The Walker family settled into this working class
neighborhood, one they believed was
safe from crime and v*olence.
The Walkers youngest child, six-year-old Nicole,
loved the neighborhood because of the large number of children
who all played together.
-She didn't like to smile.
She used to tell people, I don't know how to smile.
You'd tickle her and say, see, you can smile.
It'd always be a cockeyed smile.
Her glasses would always be cockeyed.
So I used to call her my kooky cockeyed little one.
-Just after dark on June , ,
Nicole Walker was walking home with four
other neighborhood children.
It was just after a rainstorm, and they were walking along
the side of this road where there are no sidewalks.
When they got to the front of this apartment building,
there was a large puddle of water left from the rainstorm.
Michelle and Gina Vitello were walking with Nicole that night.
They were years old at the time.
-I'm walking in the street, and there's a big puddle,
so we wanted to go through it so that we
don't have to be in the street.
And Nicole didn't want to walk through it because she didn't
want to get sick because she had no shoes on.
So Michelle picked her up, and we
started walking through the puddle.
-As we were walking in this puddle,
I had Nicole in my hands.
Everybody was telling me to watch out.
And that was about all I remember.
-And I see this car, this big-- a bunch
of lights just coming straight at us.
And I just yell, watch out!
-By the time they saw the vehicle, it was too late.
Nicole Walker and Michelle Vitello were both hit.
-I went over to check on Nicole, and I seen blood coming out
of her mouth and her ears, and I--
I knew she wasn't going to make it.
-One of the kids ran to Nicole's home.
SUZANNE WALKER: There was the knock at the door,
and it was Joel.
There was no color in his face, and his eyes
were so bugged out of his head.
He was just-- you could see the terror, the fright, just
saying, the girls were all hit.
The girls were all hit.
-The children were rushed to the hospital.
Michelle suffered a broken leg, two
broken wrists, and a lacerated liver.
Nine-year-old Brooke Mansey suffered a fractured shoulder
and facial injuries that required a dozen stitches.
Six-year-old Nicole died shortly after arriving at the hospital.
-Some internal surgeons came in, and the conclusion was, no,
she-- that she doesn't have a chance.
And I begged and pleaded even for % chance,
and they told me, no. There's no chance.
-Nicole died of severe trauma to the head
and massive internal injuries.
A witness said it was a man driving a green pickup truck
with a white camper top which sped away quickly, ran
this red light, and disappeared.
MICHELLE VITELLO: I VITELLO: was just
wondering why-- how can somebody, like, just hit people
and just keep going without even caring, like,
what was going to happen to them and just left
us-- just left us to die and-- it's
just a-- just-- scary feeling.
I didn't know if they were ever going to find them or what.
-Investigators were hoping that science could identify
the pickup truck and the driver.
-How could you hit five little kids and keep on going?
-Suzanne Walker was grief-stricken and angry
over the death of her daughter Nicole.
-How could you do that?
How could anybody hit kids and keep on going?
Just to know you laid them flat out in the middle of a road
and by-- you had to know.
-Detective Bruce Babcock, a member of an elite team
of accident reconstructionists, was called to the scene.
Just before the accident, witnesses
said a green truck swerved off the road, knocking
over some trash cans, then stopped in a nearby cul de sac.
A few minutes later, the truck started up again,
heading back out of the neighborhood
on the same road on Southwest rd Avenue.
As it approached the apartment building,
it veered off the road into the puddle,
hitting three of the five children,
k*lling six-year-old Nicole Walker.
Witnesses said the truck picked up
speed after fleeing the accident.
Bruce Babcock took detailed measurements
of the accident scene and photographs.
DET.
BRUCE BABCOCK: When we got to the scene,
the grill piece has been found, uh, in the puddle
by a citizen, who later gave it to one
of the initially responding deputies.
Uh, there was also a piece of clothing that, uh, from Nicole
that we found in the puddle itself.
-The grill was unique.
It had come from special edition
Chevrolet Silverado pickup truck.
Babcock also found pieces of plastic
from the front turn signal lens of the truck.
Forensic chemist Bruce Ayala hoped that Nicole's clothing
would contain vital evidence.
BRUCE AYALA: The first area of interest in my analysis
was to examine the victim's clothing,
because many times in hit and run accidents
where pedestrians are involved, there
is paint transferred from the front end of the vehicle
to the victim's clothing.
-Ayala did find paint on Nicole's clothing.
Under a microscope, he discovered that the chips
actually contained six different layers of paint,
but the outer layer of paint was blue and not green,
as the witnesses had indicated.
The grill left at the scene matched the pattern injury
on the back of six-year-old Nicole Walker,
and the head injury on the back of her head
indicated that Nicole's head most likely
hit the hood portion of the truck.
Investigators now changed the description of the truck
and notified the public to be on the lookout for a blue
Chevrolet Silverado pickup truck with possible front end damage.
KENNETH PADOWITZ: And in essence, there was a man hunt
in an attempt to look for this vehicle,
because the investigators knew that if they found
this vehicle, there was a great likelihood that they would be
able to determine who was the driver of this truck
and responsible for Nicole's death.
-News reports of the hit and run accident
outraged the community.
Detectives searched all over Florida
for the blue Silverado pickup truck.
Three weeks went by, then an anonymous caller told police
that a blue Silverado pickup truck was in a driveway
about miles from the accident scene.
KENNETH PADOWITZ: This deputy arrived at the home,
got out of his vehicle, and noticed
as he was walking towards the front door
that there was a truck-- a blue Silverado pickup truck-- that
was surrounded by other vehicles.
-A washing machine had been placed in front of the truck,
obscuring its front end.
The truck did not have the white camper top witnesses described.
The front grill was intact, although it was not
the original one, and the front turn signal lens was broken.
In addition, the tires did not match
tire impressions from the accident scene.
The truck was registered to a Kathryn Pierce, whose husband,
-year-old Ken Pierce, had a prior history of driving while
under the influence of alcohol.
One of the victims thought the driver was a man,
but couldn't identify Ken Pierce as the driver of the vehicle.
-The truck was just speeding at us.
All I can remember is a bright light.
Just bright lights coming straight at us.
It was-- I was so confused about the whole--
just the whole thing.
Just not even remember getting hit or nothing.
It's just weird.
Weird thing.
-Investigators faced two difficult tasks, first,
trying to prove that this was the truck involved
in the accident, and second, to figure
out who was driving the truck.
KENNETH PADOWITZ: The problem for us was developing
the evidence that was going to be needed to show who,
in fact, was the driver of this truck, who veered off
that roadway and hit Nicole Rae Walker that night
and veered back on and didn't stop.
That was going to be the challenge.
-It was now three weeks after the hit and run death of Nicole
Rae Walker, and police had the truck
they believed was involved in the accident.
But there were problems with making a definitive match.
If this was the truck in the accident,
it had been altered some time after the accident
with different tires, repairs to the front grill,
and the truck did not have the white camper
top witnesses clearly recalled seeing.
There were no fingerprints inside the compartment
of the truck, which was extremely unusual.
It appeared that the inside compartment
had been wiped clean.
District Attorney Ken Padowitz kept a picture of Nicole Walker
on his desk, a sign of his determination to find out what
exactly happened on the night of the accident.
So he turned to a new state-of-the-art scientific
tool, forensic examination, which can create
a virtual rendering of an accident.
-The best way to understand the concept of forensic animation
or reconstruction would be to understand that what we're
trying to do is visualize the opinions of other experts.
-All of the information gathered at the crash site
by accident reconstructionist Bruce Babcock
was taken into account, the horizontal
and vertical measurements of , feet of roadway,
the eyewitness accounts, the weather conditions,
and the injuries sustained by the victims.
The mechanical specifications of the Chevrolet Silverado
were also programmed into the computer.
They also calculated the approximate tire pressure
and the height and weight of their suspect,
Ken Pierce, who was foot inches tall and pounds.
All would affect the height of the truck
as it traveled down the street before striking the children.
The speed was uncertain, so they estimated the truck was
traveling miles per hour, the posted
speed limit on that road.
Michelle Vitello was carrying six-year-old Nicole Walker
on her right hip at the time of impact.
When the animators programmed this information,
they made a startling discovery.
The front grill of Kenneth Pierce's truck
would have struck Nicole Walker in the back
at the exact same place and at the same degree
angle reported by the forensic pathologist
at Nicole's autopsy.
JACK SUCHOCKI: We then took an angle of Nicole's spine
to the vertical, the height of Nicole
from the roadway or the ground.
And suddenly, it was at that point we discovered that we
could match these bruising marks and contusions
to actual elements on the front of the truck, a real revelation
to us, and certainly something that
could become very crucial in the case.
-When the animation was complete,
it consisted of three different views, an overhead perspective,
providing a bird's eye view of what happened; another
from inside the vehicle, which would have been
the view of the alleged driver, Kenneth Pierce.
From this vantage point, you can see that Nicole's head would
have hit the front hood of the truck,
causing her fatal head injury.
The third view, a so-called chase view,
was from behind the truck.
For further proof, investigators turned to the paint chip found
on Nicole's shirt at the time of the accident.
The paint chip was blue, but there
were five other layers of paint underneath.
Forensic chemist Bruce Ayala ground the paint sample
in a pestle, then analyzed it using infrared spectroscopy,
which uses infrared light to identify the chemical makeup.
The results were charted onto a computer graph.
BRUCE AYALA: They were six different layers of paint.
There was blue metallic present, blue non-metallic,
gray body filler.
Then there was a blue metallic factory paint, a white factory
primer, and a black factory primer.
Uh, subsequently, when we examined the suspect's vehicle,
we found that all six of those layers
were present on his vehicle.
-And, finally, the plastic particles found at the crime
scene were the same in color and materials
as the broken turn signal on Pierce's truck.
Although there were no fingerprints found
in the compartment of the truck, Kenneth Pierce's is
partial thumb print was found on a can
on the floor of the vehicle.
-year-old Kenneth Pierce was arrested and charged
with vehicular homicide in the death of Nicole Walker.
[honking]
[screaming]
-The forensic animation showed clearly
that the driver would have known he had hit
the children at the time of the accident.
Before the trial, Ken Pierce's neighbor Terry Jones
came forward and told police that Pierce admitted driving
the truck on the night of the accident.
DET.
BRUCE BABCOCK: Mr. Jones told us that Ken Pierce had contacted
him and requested that, uh, he come over and help fix
the damage to the front of the vehicle.
Uh, he also, uh, uh, received a camper top
that had been taken off the vehicle.
Uh, the camper top was worth about $,
and Mr. pierce gave it to him for the work
that he did on the car.
-Kenneth Pierce had a number of prior arrests and convictions.
KENNETH PADOWITZ: It should be somewhat
significant to-- to find out that, in addition to arrests
and convictions for felonies and misdemeanors in Mr. Pierce's
life, he had two prior hit and run convictions.
-At the trial, prosecutors wanted
to introduce the forensic animation to show the jury
their version of what happened on the night of the accident.
Defense lawyers claimed that the animation was nothing more
than speculation and would prejudice the jury.
Prosecutors said the animation was
a factual account of the accident.
The judge ruled that the forensic animation
was admissible.
It showed that the blue Silverado truck traveling north
on rd Avenue drove off the road
and struck some trash cans.
After the vehicle stopped briefly in the cul de sac,
it then turned around and headed south on rd Avenue.
As it approached the intersection of Griffin Avenue
in front of the apartment building,
the drug veered off the road into the puddle
and hit the children.
[honking]
[screaming]
The front grill of the truck struck six-year-old Nicole
Walker in the back at a degree angle,
leaving this deep bruise at the moment of impact.
The truck made a right turn onto Griffin Avenue and sped off.
The computer animation constructed exactly to scale
shows that it was a truck the same height
as the Chevrolet Silverado that was involved in the accident.
DET.
BRUCE BABCOCK: There was, uh, no reason for him
not to have known that it was, in fact, children
that he struck.
In fact, witnesses said that he accelerated from the scene
as he fled.
-Every single one of those jurors
had their eyes glued to that television screen.
And I can say, as I studied them and watched
them view that computer animation,
that I had every single moment of their attention captured
for that brief period of time.
-At the moment of impact, paint chips
were also deposited on Nicole's clothing, paint chips which
were later matched to Mr. Pierce's truck.
-And about front end damage to a
Chevrolet Silverado pickup truck.
He hired Terry Jones.
He hired Terry Jones to fix the front of that truck.
-In addition to the scientific evidence,
jurors heard testimony that Ken Pierce made efforts
to conceal damage to the truck after the accident
and confided to one person that he was driving the truck.
Just weeks after what would have been Nicole Walker's
seventh birthday, jurors delivered a verdict.
JUROR: The defendant is guilty of vehicular homicide,
leaving the scene of an accident with death
as charged in the information.
So say we all--
-Because of Mr. Pierce's prior convictions,
he was sentenced to years in prison.
SUZANNE WALKER: I'm very glad about that.
This man had seven priors in the state of Florida.
He never once ever admitted to what he did.
He's got so many priors back to .
And I'm sorry.
I don't want this man in our society.
-This case was the first time forensic animation had been
admitted into evidence in a Florida court
and only the third time in the United States.
-Trial lawyers, whether they be criminal, prosecutors,
or defense attorneys, or civil lawyers,
now have an opportunity to use dynamic new form of evidence
to educate jurors about issues that are before them
in courts all over this country.
-But for the victims, Kenneth Pierce's behavior that night
still raises questions for which there are few answers.
SUZANNE WALKER: Why didn't you stop?
Why didn't you stop?
Why did you just hit kids, plow into them,
leave them there to die in a puddle, and just keep on going?
Just, you know, that's the biggest thing.
Why?
Why not just stop?
-Well, this case involved the death of a little girl.
And I became determined to ensure
that justice was done for her.
And Nicole Rae Walker's family blew up, uh, a photograph
of their daughter and had a tear painted on her cheek.
And they presented Detective Babcock and myself
with a copy of this picture, and I have that picture
in my office, and it sits there.
And I view it every day because that photograph reminds me
that justice can still be had in the criminal justice system.
And the day that I don't feel that way anymore
is the day that I'm going to take down her picture.
