The Washington State Patrol’s crime lab identified 379
suspects from DNA samples in 2010, a record.
Every offender in the state convicted of a felony, and even some
gross misdemeanors and misdemeanors, has to submit a DNA sample,
which goes into a database, the state patrol said Tuesday in a
release. Sex and kidnapping offenders provide samples as well.
That database has grown to 194,000 people in its more than a
decade of existence, so not surprisingly, more “hits” are coming
back when police agencies around the state submit a DNA sample from
a crime scene.
Here’s more from a news release by the state patrol:
In June of 2009 an unknown male robbed a grocery store in
Spokane. A wig and fake beard matching that worn by the
suspect were discovered along the escape route and submitted to the
crime lab. DNA recovered from both items was linked to a
convicted offender in the CODIS database. Due to a previous drug
conviction in 2006, he had been required to provide a DNA sample
for the database. Faced with the evidence, the suspect pled guilty
to robbery in May 2010.
DNA testing completed by the Washington State Patrol Crime
Laboratory Division resulted in a record 379 hits in 2010 using the
Combined DNA Index System (CODIS). Since it was implemented
over a decade ago, this crime-fighting tool has provided
investigators with over 1,500 leads.
“This is about arresting and convicting the guilty, and clearing
the innocent,” said WSP Chief John R. Batiste. “DNA is the most
reliable way we’ve ever had for telling if someone was present at a
Located in Seattle, the WSP CODIS Laboratory receives
approximately 1,400 convicted offender samples each month. The
resulting database contains over 194,000 DNA profiles from
Washington state offenders convicted of a felony, or certain gross
misdemeanors and misdemeanors. State legislation also requires that
registered sex and kidnapping offenders submit a DNA sample.
Samples from convicted criminals are compared regularly with DNA
evidence retrieved from the scenes of more than 3,500 crimes
statewide. Samples in the state database are also routinely
searched against the nationwide CODIS database.
In 2010, over half of Washington’s CODIS hits were linked to
burglary cases, while approximately 39% were hits in connection
with violent crimes such as homicide, rape, robbery, and
Of note is that 79% of the DNA hits were from convicted
offenders whose profiles were in the database for typically less
violent crimes, such as burglary or drug possession. This shows the
value of capturing DNA from those convicted of less severe, mostly
In addition to being an all-time high, the 379 hits generated in
2010 equal a 47% increase over the 257 hits in 2009. This
marked increase is attributable to a number of factors, including a
pilot project testing evidence from property crimes, and technology
improvements implemented by the WSP Crime Laboratory Division.
“The CODIS program is a forensic time machine”, said Forensic
Laboratory Services Bureau Director Larry D. Hebert. “Our
scientists use this powerful technology to link suspects to
unsolved crimes, some of which were committed over 40 years ago.
CODIS is also used to link apparent unrelated cases to each
other providing investigators with valuable information.”
