The Weber County attorney's office is awaiting written autopsy results before deciding how to handle the case of a Weber State College golfer who died after he was punched during a weekend altercation.

County Attorney Reed Richards said Wednesday that witnesses were still being interviewed, and if a charge is warranted in the case, it probably will not be filed until next week.

A preliminary report from the state medical examiner indicated that Mark Alan Doherty, 21, died of a head injury sustained when he fell and struck his head on the concrete floor of a parking terrace, said Ogden Police Detective John Stubbs.

A 23-year-old Roy man was arrested and booked into jail for investigation of manslaughter Sunday night. However, he was released on his own recognizance and has not been charged in the death.

Doherty, a member of the college's golf team, was taken to McKay-Dee Hospital and pronounced brain-dead shortly after the altercation. He died later in the day after life-support machinery was disconnected.

Two companions told police they were with Doherty in the parking terrace after a party when a motorist they had asked for a ride exchanged words with Doherty. They said the driver got out of his car and punched Doherty in the face twice. Doherty fell backward, they said, his head striking the concrete.
