A man who pleaded guilty to raping a child last year has now been identified as a suspect in a child rape from 1993 thanks to new DNA evidence, Manhattan District Attorney Cyrus Vance announced yesterday.

Vance announced that William Dixon, 58, was indicted for sodomy in the first and second degree this week for an attack on an 11-year-old girl in Hamilton Heights in February 1993. According to the D.A.'s office, Dixon allegedly forced the girl onto the roof of her building at knifepoint in 1993, where he then sexually assaulted her.

Evidence for a rape kit was collected when the girl was treated for the assault, but no DNA match was made until recently. The DNA profile was uploaded to the FBI's Combined DNA Index System (CODIS) in 2002 but didn't come up with a match, but the DA's office got a "John Doe" indictment based on the profile the next year.

After Dixon plead guilty in January to raping a 12-year-old girl in the Bronx last November, his DNA was uploaded to CODIS, where it matched up with the evidence from the 1993 rape.

"It is my sincere hope that our Office’s $38 million initiative to test backlogged rape kits across the country will result in justice for victims and bring closure to survivors for decades to come," Vance said in a statement announcing the indictment.
