Jack Owen Spillman III (born 30 August 1969) is a serial killer from Spokane, Washington. He is known as 'The Werewolf Butcher'. Spillman was convicted of the murders of a 48 year-old East Wenatchee, Washington woman and her 15 year-old daughter in April 1995, and the murder of a 9 year-old girl in 1994. Spillman's black pickup truck matched the description of a vehicle seen in the parking lot of the victims' home on the night of the murder. That evening Spillman was stopped in the parking lot of a VFW hall nearby. Later a knife was recovered at that location. It was a 12-inch knife covered in blood and appeared to match a knife set in the victims' home. Before he was arrested, Spillman was kept under surveillance for a week while laboratory tests were performed. The woman and her daughter had both been sexually mutilated and posed in provocative positions. Under threat of the death penalty, he later admitted to killing a 9 year-old Okanogan County girl the previous year.
