(KFOR) 33-year-old Brad Davis is under arrest for taking a high school prank to a deadly level.
Authorities say he killed his stepfather with an "atomic wedgie."
Investigators say Davis and his 58-year-old stepfather, Denver St. Clair, were drinking together inside the family home a few days before Christmas.
According to the police affidavit, tempers flared when "St. Clair began speaking ill of Davis' mother" and a fight broke out.
