A Texas man who admitted to killing his mother and raping her corpse clowned around for jurors who are considering his sentence.

Kevin Davis pleaded guilty Monday to first-degree murder, just as his trial began.

Prosecutors played a videotaped confession Tuesday to jurors, who heard the 18-year-old admit he tried to strangle Kimberly Hill with the power cord from a video game console on March 27, but when she did not stop screaming, he struck his mother’s head repeatedly with a hammer.

Davis told investigators on the recording that he stuck his hand into the open wound and moved her brain around to make sure she was dead, reported KZTV-TV.

Then, Davis told investigators, he raped his mother’s dead body.

“Guess I lost my virginity to a dead corpse,” Davis said.

Davis watched the video intently, and when it was over, he swiveled his chair to face the jury and smiled, reported the Corpus Christi Caller Times.

Davis told detectives he had long fantasized about killing his mother and sister, and he waited a while for his sister to return home before deciding to leave his family’s Corpus Christi apartment and move away.

“I had my fill of killing,” he said. “It seemed a little much.”

He rode his bicycle along some train tracks before knocking on a couple’s door and asking them to call police because he’d murdered someone.

Davis waved at the couple as they testified and prosecutors asked them to identify him in the courtroom, the newspaper reported.

Police found a trail of blood from the living room to the master bedroom, along with handwritten notes from Davis.

“Chase me,” one read. “Sorry for the mess. KD.”

Jurors cringed and covered their faces as Davis told detectives that he had once choked and drowned a cat and then performed a sexual act with its remains, the Caller Times reported.

He also described his fantasy of dressing in a suit, decapitating a girl, putting her in a dress, and having sex with her corpse.

“It would be a night to remember,” Davis told detectives.

Davis told detectives during the videotaped interview that Hill was “the best mother” and didn’t deserve to die, and police asked him if he regretted killing her.

“In a way, yes, but I wouldn’t take back what I did,” he said. “I did love her in a way. I’m a terrible, disgusting person.”

Davis told police he asked his mother for permission to die because he was bored with life and did not like other people, and he said she was upset but told him she could not control what he did.

So he decided to kill her, Davis told detectives.

“I don’t have standards, I don’t have morals. A body’s a body — a piece of meat,” Davis said.

Davis, who was sentenced Wednesday to life in prison, told detectives he deserved 100 years for what he had done, although he admitted he would kill again.

“I’m not mentally disturbed, I’m sane,” he told detectives. “I know what I did.”
