A man convicted of killing his rape victim by tying her to a bed in her house and then setting the place on fire went to his execution maintaining his innocence.

Jerry Lee Hogue, 47, was executed by injection Wednesday evening."I don't know why you're doing this but I'm going to forgive you," Hogue said from the death chamber gurney, directing his final comments to an execution witness who was one of the fire's survivors.

Hogue was convicted of terrorizing four people, including Jayne Markham and her 8-year-old son, in their Arlington home, and then dousing it with gasoline and igniting the fuel. All but Markham, 27, escaped the flames in the early hours of Jan. 13, 1979.
