A former Dorchester resident was sentenced to 18-20 years in state prison today after he admitted he raped a woman walking home from the Savin Hill MBTA stop on Oct. 30, 1992.

Terry Abercrombie, 52, had avoided detection until 2012, when a DNA database run by the FBI found a match with DNA evidence the Suffolk County District Attorney's office had entered in the database in 2006.

DA Dan Conley said the DNA match and additional evidence convinced Abercrombie to plead guilty.

According to the DNA's office, Abercrombie pulled the woman into a driveway off Cushing Avenue, took cash, then raped her.

"The victim was treated first at St. Margaret's Hospital and then at Boston City Hospital, where a rape kit was performed. Evidence from that kit was maintained for years by Boston Police and uploaded into the FBI's Combined DNA Index System, or CODIS, in 2006 as part of a program to solve cold cases with DNA evidence."

In January of last year, a Suffolk County grand jury indicted Abercrombie. He was scheduled for trial this year.
