A popular Pennsylvania DJ has pleaded guilty to raping and strangling a schoolteacher in 1992 after being identified as a suspect as a result of DNA a relative submitted to a genealogy database.
Raymond Charles Rowe apologised in court on Tuesday for killing 25-year-old primary school teacher Christy Mirack at her apartment in Lancaster. He was sentenced to life without parole.
The case had stymied investigators until authorities used a genealogical database to identify a half-sister of the then-unknown suspect, leading them to the 50-year-old Rowe, who lived just metres from where the murder occurred.
Undercover detectives obtained DNA from Rowe by collecting his used water bottle and chewing gum at a school where he was DJing last year.
