Police Use DNA In Spit To Link Man To Murders of Two Young Women

This controversial DNA technique has also been used to arrest the Grim Sleeper, Lonnie Franklin, Jr., in his serial killings that spanned from 1985 to 2007.

Authorities used DNA from spit on a sidewalk to link a man to two 2011 slayings in Los Angeles.

According to the Associated Press, a man already suspected of sexually assaulting and killing two young women was tied to the crime after police analyzed the spit.

Geovanni Borjas, 32, was identified as a suspect in the killings of Michelle Lozano, 17, and Bree'Anna Guzman, 22, after Los Angeles investigators used a DNA testing technique known as familial DNA testing.  This technique is considered controversial. It allowed investigators to compare forensic evidence from the victims to law enforcement databases to identify likely relatives of the person who committed the crime. This particular search resulted in a match to Borjas' father, whose DNA was on file from a prior arrest.

Detectives began following Borjas and after he spit on a sidewalk, they collected his DNA. That sample matched the DNA that was collected from the crime scenes. Borjas was arrested last Thursday and charged Tuesday with two counts each of murder and forcible rape, and one count of kidnapping.

Lozano was found dead April 25, 2011, a day after she disappeared from home. Her body was found wrapped in plastic bags and stuffed inside a container that was dumped in the brush along an Interstate, according to police. She had been strangled.

"Michelle was murdered, she was sexually assaulted and she was discarded," police stated. "These two murders were horrific."

Guzman disappeared on Dec. 26, 2011 after going to a nearby pharmacy to buy cough drops. Her body was found a month later along a highway ramp.

He's in jail and he's never going to leave," Guzman's father, Richard Duran, said in Spanish, according to Fox News. "That gives me a lot of happiness. I have closure now."

Investigators are still trying to determine if Borjas knew the victims. So far, he hasn’t cooperated.

This DNA technique has only been used a handful of times in Los Angeles. It has been used to arrest the Grim Sleeper, Lonnie Franklin, Jr., in his serial killings that spanned from 1985 to 2007 according to Fox News. It was also used earlier this year to solve the decades-old killing of the ex-wife of Righteous Brothers singer Bill Medley.
