Teen stabs sleeping 9 year old to death and gives a shocking reason.

William Schultz, 18, was a guest in the victim's house but turned that hospitality into a painful memory for parents of the 9 year old child he murdered.

On Saturday, the day before the murder took place, Schultz had stayed the night at the victim's home in Discovery Bay, a waterfront community along the Sacramento-San Joaquin River Delta.

He told reporters that his family had been concerned about his odd behavior and mental health over the last month and that he was briefly hospitalized Saturday in a county facility. He said a doctor discharged him and sent him in a cab to his mother's home where a fight between him and his mother ensued. He says that's why he went to spend the night at the victim's home. Schultz and the victim's older brother have been friends since 6th grade.

Sheriff's deputies were called to the victim's house at about 10 a.m. Sunday but the boy's family had whisked him to the hospital before authorities arrived. The boy was pronounced dead at the hospital.

Schultz was arrested about five hours later when he went to Kaiser Antioch Medical Center to be treated for slash wounds. It was there that a nurse recognized from social media that Schultz was wanted by the authorities and called police. Schultz told the paper he accidentally cut his right wrist while stabbing the boy. Schultz showed the Times reporter his fresh stitches.

The Contra Costa Times reported Monday that 18-year-old William Schultz said he killed the sleeping boy because he wanted to know what it felt like to murder someone before the world ended.

His reason is one of the most 'stupidest' things I've ever heard. So dumb and atrocious.
