Police are hunting John Clifford after he failed to return to prison following day release
John Clifford, 56, was allowed out of Maghaberry Prison, Northern Ireland, on Sunday to attend an appointment.
But the convicted murderer did not return to prison and he has still not been traced.
Clifford raped and murdered his eight-year-old niece Sue Ellen Clifford in 1988, the Belfast Telegraph reported.
The 56-year-old has been convicted of murder, in addition to other offences including cruelty to children and indecent assault, according to the Northern Ireland Prison Service’s website.
