NEW ORLEANS - New Orleans police have arrested a suspect in 1985 rape.

Troy Williams, 42, was arrested in Texas and transferred to New Orleans Wednesday, where he was jailed on rape, armed robbery, aggravated kidnapping and other charges, The Times-Picayune reports.

Police say they found Williams after the Louisiana State Police crime lab checked an evidence kit from the assault for DNA. The DNA found by the lab matched a sample from Williams in an FBI-managed database.

Police say Williams and another man assaulted a woman on the morning of Aug. 21, 1985. Authorities say the men stole the woman's purse after putting a gun to her head, then forced her into an alley and raped her.

Williams was 15 when the rape occurred, but will be tried as an adult.
