Brad Lee Davis is an Oklahoma man who gained national attention when he was convicted of killing his 58-year-old stepfather, Denver Lee St. Clair, during a drunken physical altercation in December 2013. Davis, a former U.S. Marine, claimed the fight began after St. Clair insulted Davis's mother. After knocking St. Clair unconscious, Davis pulled his stepfather's underwear waistband up over his back, head, and tightly around his neck in a severe variation of the prank known as an atomic wedgie.
