— Authorities have arrested a man in the bizarre killing of his stepfather, who was found with his own underwear stretched around his head and neck. The stepson called it an “atomic wedgie.”

Brad Davis, 33, of McLoud, was arrested on a murder complaint Tuesday evening in the death of Denver Lee St. Clair, 58. St. Clair was the husband of Tressia St. Clair, Davis' mother.

McLoud police and Pottawatomie County deputies were called about 10:10 p.m. Dec. 21 to 4 Shadow Lake. Davis said he and St. Clair fought, and he thought St. Clair was dead, according to a probable cause affidavit.

When authorities questioned Davis, he said St. Clair asked him to come over for drinks. The men began arguing and Davis told officers that St. Clair “came at him,” and they began exchanging blows.
