Trevor Hamilton (born 19 June 1982), is a Northern Irish murderer. He abducted and murdered 65-year-old Attracta Harron, a recently retired librarian, when she was returning from Mass in Murlog, Lifford, County Donegal on 11 December 2003. Four months earlier he had been released from prison after serving a sentence for a violent rape and other offences, including threats to kill. Attracta Harron's body was found on 5 April 2004, four months after she was last seen alive, hidden in a river bank less than 50 yards from Hamilton's home.
