DAVIS (KPIX 5) A Northern California laboratory is providing crucial evidence in murder investigations using DNA extracted from the pets of crime victims.

The Forensics Unit of the Veterinary Genetics lab at the University of California, Davis is the go-to lab for getting results that qualify for convictions in court.

We are the only accredited laboratory in the world doing this type of work, said Beth Davis, a scientist with the UC Davis lab.

The scientists here isolate animal DNA for use in cases ranging from abuse to horse-breeding to cold-blooded killings.

If you own a dog or a cat, you know, youve got fur on your pants. You go to your car, it gets in your car and youre carrying their DNA, their signature with you everywhere you go, said Davis.

In 2008, Steven and Linda Riley were stabbed to death in their home in Sacramento County, their bodies discovered after they failed to show up to their jobs.

The bloody crime scene did not have any blood from any suspect, and the couples family had no idea who could have done it.

Eventually, the suspicion centered on the couples son, Matthew, even though there was no physical evidence pointing to his involvement until prosecutors took a close look at a pair of boots found on the roof of his former apartment building two years after the murders.

The idea was that he most likely killed in his socked feet and put his socked feet back into those boots and drove home, said Sacramento County Deputy District Attorney Chris Ore.

NorCal Lab Analyzing Animal DNA In Murder Investigations

Posted: November 8 Updated: Today at 12:09 AM A judge must decide if the Maine man convicted of murdering 12-year-old Sarah Cherry in 1988 gets a new trial.

The legal fate of Dennis Dechaine now rests, as it has for 25 years, in the hands of Superior Court Justice Carl Bradford.

Dennis Dechaine, shown in court in Portland on Thursday, was convicted in 1989 of the murder of 12-year-old Sarah Cherry.

Bradford, 80, retired in 1998 but is still an active judge and is called upon to preside over certain cases, including that of Dechaine, whom Bradford sent to prison for life in 1989.

On Thursday and Friday in a Portland courtroom, Bradford listened to testimony from DNA experts. He now awaits written arguments from the defense and prosecution before he determines whether Dechaine is granted a new trial.

Deputy Attorney General William Stokes will argue that Dechaine does not deserve a new trial. The state believes that he alone is responsible for the 1988 killing of 12-year-old Sarah Cherry and no amount of DNA analysis is going to change that.

Defense attorney Steven Peterson, who has handled Dechaines appeal since 2004, is hoping that the new DNA analysis presented over the last two years, including more this week, is enough to establish the smallest amount of doubt.
