Man who volunteered his DNA convicted of three murders in NYC suburb

(CBS/AP) WHITE PLAINS, New York  - A man who voluntarily gave up the DNA that implicated him in three murders was convicted Monday.

Francisco Acevedo, 43, was found guilty of killing three women in the New York City suburb of Yonkers more than 15 years ago.

The victims were found strangled, naked and bound at the hands. Police found DNA at the scene, but did not know whose it was until 2009 when Acevedo, who was in prison on a drunken driving charge, gave a DNA sample as part of a parole application.

According to a Yonkers cold-case detective, police had looked at more than 100 suspects over the years before they matched Acevedo's DNA to the murder scenes.

At trial, an expert testified it was statistically impossible for the DNA found in vaginal swabs from each of the women to be anyone's but Acevedo's. And a motel clerk said he saw Acevedo with one of the women and then found her dead in her bed.

The victims were Maria Ramos, 26, of the Bronx, killed Feb. 5, 1989; Tawana Hodges, 28, of the Bronx, killed March 28, 1991; and Kimberly Moore, 30, of Greenburgh, killed May 24, 1996.

Acevedo was acquitted of three counts of rape in the same case. Police had said Ramos and Hodges were prostitutes.

Acevedo faces 75 years to life in prison when he's sentenced on Jan. 17.
