Criminal justice contends with CSI syndrome

Wellington Correspondent
Wellington residents learned in October that using DNA testing to solve
crimes is more than television drama.
At an Oct. 13 press conference at Wellington Town Hall, Larimer County
investigator John Feyen mentioned that a "rush" had been placed on analyzing
DNA samples during the investigation of a sexual assault and burglary in
town. When asked what was the most difficult aspect of the case, he laughed
and said, "Waiting for the phone to ring with the lab results."
It seems that lots of people have "CSI expectations" when it comes to getting
rapid answers to evidence requiring modern laboratory tests. Although Feyen
enjoys watching the popular TV crime show, too, its one-hour crime wrap-ups
featuring all the latest in crime-solving technology can skew people's
expectations.
As fans of the show know, crime lab analysts arrive quickly on the scene.
In Wellington, Feyen said, a member of Larimer County's three-person team
handled the collection of evidence. He added that patrol officers are trained
to perform basic evidence processing such as taking photos, dusting for
fingerprints and recording shoe prints and tire impressions, when necessary.
Samples collected from the Sept. 18 assault were sent for DNA testing to
the Colorado Bureau of Investigation on Sept. 23. Early on, investigators
also collected DNA samples from three possible suspects, Feyen said, but
the lab results pointed to one suspect and led to the arrest of Benjamin
William Vivian, 24.
Feyen's phone rang with the results on Oct. 12. "Sometimes," he said, "lab
results can take as long as six to seven months."
Ron Arndt, agent in charge who handled the samples at CBI, said the length
of time for producing results depends largely on the number of cases to
be handled and the lab people available to perform the tests. A backlog
has developed since the late '90s due to changing technologies that allow
more and more evidence to be analyzed for DNA testing. Thus, law enforcement
agencies request more tests.
The backlog is now dropping because of a grant from the legislature that
has allowed upgrades in equipment and the addition of database analysts
to the staff. "We are seeing a reduction (in the backlog) on a monthly
basis," Arndt said, "but it will take some time to reduce it completely."
Arndt noted that the absolute minimum time to get results from DNA testing
would be 24 to 48 hours, and that would be possible only if staff were
working 24/7, a situation that might occur, for example, if a serial rapist
would otherwise be at large. If one analyst worked normal hours on a single
case, with no interruptions, and had a limited number of samples to deal
with, he said, the results could be forthcoming in three to four days.
Arndt said the six-month delays experienced by Feyen in the past were a
result of the accumulated backlog.
The Denver lab of CBI performs the bulk of testing, aided by labs in Montrose
and Pueblo. Arndt said all three labs could perform the required DNA tests.
"We do no outsourcing of DNA testing," said Arndt.
Labs often must work with small samples of fluid or tissue on clothing
or other materials, said Arndt, but lab analysts also leave enough of a
sample so that retests can be done if requested by the defense.
