A Prince George’s County jury on Tuesday convicted a Largo man of first-degree murder in the 2007 stabbing death of a 53-year-old woman, State’s Attorney Angela D. Alsobrooks said.

Troy S. Nash, 49, of Largo, was found guilty of first-degree murder, prosecutors said. He was convicted of killing Vanessa Gail Riddick inside her Largo apartment.

On Aug. 31, 2007, county police went to Riddick’s apartment after her daughter reported that Riddick was not answering the phone or responding to knocks on her door.

Police went inside and found Riddick’d body. She had been stabbed 65 times, authorities said.

Police found blood in the hallway outside of the apartment. In September 2009 the National DNA Index System told police that Nash’s DNA was a match to DNA found outside the apartment, prosecutors said.

DNA experts testified at Nash’s trial that the chances that someone other than Nash had the same DNA profile as was found at the crime scene was one in 680 trillion, prosecutors said.

Nash has been previously convicted of motor vehicle manslaughter, assault, burglary, and robbery, authorities said.

“A terrible, heinous crime was committed. A career criminal was convicted. Let justice be done for Ms. Riddick and her family,” Alsobrooks said.

Nash is scheduled to be sentenced Nov. 18.
