Hit with a hammer about 20 times

On March 27, 2014, Kimberly Diane Hill was killed by her teenage son. Kevin Davis used a cord from a video game controller to strangle Kimberly. When she began to scream, he hit her in the head with a hammer about 20 times. Finally he drove a knife, and then his own fingers, into her fractured skull. Once she was dead, Kevin had sex with his mother’s corpse.
