HOUSTON » A teenage suspect is accused of raping and fatally choking his 15-year-old girlfriend then stuffing her body in a kitchen cabinet in an abandoned Houston-area apartment.

The Houston Chronicle reports that court records show the teenager used his cellphone to record the sound of Karen Perez begging for him to stop attacking her.

Perez was reported missing after she failed to return home from school Friday. Her body was found Monday in South Houston.

The suspect is under 17. His name hasn’t been released.

Harris County prosecutors say the teen and his father joined the search for Perez Sunday but that the parent turned him in when he said he knew she was not alive.

Prosecutors say the teen confessed when confronted with the recordings, threatening texts and other evidence.
