Jack Owen Spillman III (born August 30, 1969)[3] is an American rapist and serial killer from Spokane, Washington.

[5] Spillman's black pickup truck matched the description of a vehicle seen in a parking lot near the victims' home on the night of the murder.

Also, Spillman's pickup was stopped by an East Wenatchee police officer in the parking lot of a VFW hall nearby that evening, and subsequently, a 12-inch knife covered in blood was recovered there.

According to court documents, "Spillman would declare to [cellmate Mark] Miller that he wanted to be the world’s greatest serial killer".

At the time that he pleaded guilty to the three murders, reports stated that Spillman was facing additional charges of first-degree rape, robbery, and burglary.
