COLUMBUS, Ohio -- Attorneys for a death row inmate sentenced to die for fatally stabbing a 67-year-old man are asking the Ohio Parole Board for mercy for their client.

Raymond Tibbetts is scheduled for execution in April. He was convicted of killing Fred Hicks at Hicks' Cincinnati home in 1997.

The parole board meets Tuesday to hear arguments for and against clemency for Tibbetts.

Records show that Tibbetts first killed his wife, 42-year-old Judith Crawford, by beating her with a bat and stabbing her during an argument over Tibbetts' crack cocaine habit. Tibbetts then killed Hicks, who had hired Crawford as a caretaker and allowed the couple to stay with him.

Tibbetts was sentenced to death for the killing of Hicks and life imprisonment without parole for Crawford's death.
