SAN FRANCISCO (AP) _ Reagan administration adviser David A. Winston has died of injuries he suffered when he was attacked by a motorist in a traffic dispute.

Winston, 44, an unpaid consultant to the Reagan administration on health issues, died of respiratory arrest at San Francisco General Hospital on Thursday.

Police said Winston walked across an intersection against a red light on Saturday, forcing a driver to slam on his brakes to avoid him.

The inspectors said Andrew Heagney, 22, of South San Francisco got out of his car and hit Winston in the mouth, knocking him to the ground.

Winston suffered a cerebral hemorrhage when his head hit the pavement during the altercation.

Heagney was arrested and booked into city jail after turning himself in late Thursday, police said. District attorney's officials were scheduled to meet today to determine specific charges against him.

Heagney's attorney, Steven Chase, said his client would not comment on the case.

Winston, senior vice president of Voluntary Hospitals of America and vice president of the hospital development firm American Health Capital, was a resident of Alexandria, Va. He was in San Francisco on business.
