Fingerprint
Technology Played Key Role
A cold case is just that—an
investigation of a crime, usually a violent one, where all leads have been
exhausted and the trail has gone cold. But in recent years, the use of various
technologies has begun heating up many of these cold cases, uncovering new
leads for investigators and providing justice for victims.
One immediate technology example that
comes to mind is automated fingerprint searching—more precisely, searches of
latent prints of violent unknown perpetrators left at crime scenes. The FBI’s
Integrated Automated Fingerprint Identification System (IAFIS), which houses
known records for approximately 73 million criminal subjects, is used daily by
local, state, tribal, and international law enforcement for current cases, but
increasingly for help in solving cold cases as well. And once a year, the
Bureau’s Criminal Justice Information Services Division recognizes an outstanding
major case solved with help from IAFIS.
The 2012 Latent Hit of the Year Award
was presented last month to two employees of the Omaha Police
Department—Detective Douglas Herout and Senior Crime Laboratory Technician
Laura Casey—for their efforts to identify the man responsible for a brutal
murder more than 30 years ago.
The crime: In 1978, 61-year-old Carroll
Bonnet was stabbed to death in his apartment. Police collected evidence,
including latent fingerprints and palmprints from the victim’s bathroom
(officers believed the killer was trying to wash off blood and other evidence
before leaving the apartment). The victim’s car was then stolen.
The investigation: The car was found in
Illinois, but after collecting additional latent prints, investigators couldn’t
develop any new leads. The crime scene evidence was processed, and latent
prints recovered from the scene and the car were searched against local and
state fingerprint files. Investigators also sent fingerprint requests to
agencies outside Nebraska, but no matches were returned and the case soon went
cold.
The re-investigation: In late 2008, the
Omaha Police Department received an inquiry on the case, prompting technician
Laura Casey to search the prints against IAFIS (which didn’t exist in 1978). In
less than five hours, IAFIS returned possible candidates for comparison
purposes. Casey spent days carefully examining the prints and came up with a
positive identification—Jerry Watson, who was serving time in an Illinois
prison on burglary charges.
The case was officially re-opened and
assigned to the cold case squad’s Doug Herout. Working with laboratory
technicians and analysts, Herout reviewed the original evidence from the case,
including a classified advertisement flyer with “Jerry W.” scribbled on one of
the pages. Herout also discovered that Jerry Watson had lived only a few blocks
from where the victim’s car was recovered.
And the discovery was made just in
time—Watson was just days away from being released from prison.
Herout traveled to Illinois to question
Watson and presented him with an order to obtain a DNA sample. Subsequent
testing determined that Watson’s DNA matched DNA recovered at the crime scene,
a finding that—combined with Watson’s identified prints—resulted in murder
charges and a conviction. On October 17, 2011—33 years to the day that Bonnet’s
body was discovered—his killer was sentenced to life in prison.
It’s yet another example of the vital
role that technology plays in getting dangerous criminals off our streets.
Latent prints are impressions—usually
invisible to the naked eye—often left at crime scenes that are produced by the
ridged skin on human fingers, palms, or soles of the feet. The FBI’s IAFIS
receives an average of 700 latent search requests per day from authorized law
enforcement agencies…with an average response time of one hour.
Our Next Generation Identification
system, an incremental replacement of today’s IAFIS, will specifically focus on
the latent user community next March when a National Palmprint System (NPPS) is
scheduled to be established. The NPPS will create a centralized repository of
known palmprints within the FBI’s database, allowing searches of unknown
palmprints against the repository…as well as searches of known palmprints
against the Unsolved Latent File. Both types of searches will enhance law
enforcement’s ability to identify criminal and terrorist suspects.
