The Utah Board of Pardons says a man who shot his roommate to death 11 years ago could be violent again and he must serve out the full 15-year sentence.

The board Friday ruled that Frank Edward Moxley, who shot his roommate to death during an argument in 1978, will be released on Nov. 5, 1993. Moxley is serving one to 15 years for manslaughter.In addition, board members said they would recommend he be evaluated upon release from prison for possible civil commitment to a mental hospital.

Moxley told the board he has been a paranoid schizophrenic since he was 5 years old. At 12, he began fantasizing about killing people.

He was discharged from the United States Marines after they found him to be mentally ill. Among other things, Moxley told Marine psychiatrists he would like to go to Russia and kill as many people as possible.

"Do you think you're dangerous, Mr. Moxley?" asked board member Paul Boydon.

"We're all dangerous," replied Moxley. "I'm dangerous, you're dangerous. That's life, we're all dangerous."

In 1973, Moxley was imprisoned in California for a stabbing and was later put into a mental hospital after he committed an armed robbery. With the help of a woman friend - whom Moxley claimed he coerced - he escaped the hospital and came to Utah.

In 1978, he killed Richard W. Evans, 46, Salt Lake City, during an argument at their apartment by shooting him in the neck with a .22-caliber handgun.

Moxley called the shooting "a very psychotic situation - madness. It was like a horror movie."

While at the Utah State Prison, Moxley's transgressions include throwing human waste at prison guards and spitting at them.

Recently he wrote a threatening letter to an employee of the state Court of Appeals.

"I lost my temper," said Moxley, adding that he later wrote other letters "asking forgiveness."
