A Texas teen was sentenced to life in prison for killing his mother with a hammer and then having sex with her corpse.

Kevin Davis, 18, tried killing his mother, Kimberly Hill, 50, first with the cord from a video game controller. When that didn't work, he grabbed a hammer and hit her in the back of the head 20 times, Mirror reports.

But he wasn't done with his mother just yet.

"I had sexual intercourse. Guess I lost my virginity to a dead corpse," Davis told police.

After sexually abusing his mother's body he waited in the apartment for his sister, Desirae Hill, to come home, who was supposed to be his next victim. However, he didn't feel like killing anymore that day so he left on his bicycle.

"I had my fill of killing. It seemed a little much," he told police in an interview. 

Davis planned the killing, and even admitted to fantasizing about killing his mother and sister in the interview. He said he was just bored and didn't like people.

The teen's perfect fantasy was divulged in the interview: dressing in a suit, beheading a girl, putting the corpse in a dress, and having sex with the body.

"I'm not mentally disturbed. I'm sane. I know what I did," Davis said during the interview.

It reportedly took the jury less than an hour to find Davis guilty, who smiled throughout his entire trial. He will be spending the rest of his life in prison.
