Tucson police are investigating the death of a bicyclist who was assaulted by a motorist in November as a possible homicide.

On Nov. 17 at 5:40 p.m., William Edwards, 55, reported to police that he was riding his bicycle near East Pastime Road and North Stone Avenue when a motorist began arguing with him, said Sgt. Pete Dugan a Tucson Police Department spokesman.

Edwards told police that the motorist got out of his car, pushed him off his bicycle and punched him several times in the face before leaving the area, Dugan said.

Edwards complained of chest pain and was taken to a hospital for treatment. Edwards left the hospital late that evening, but returned hours later and died, said Dugan.

The man who reportedly assaulted Edwards was driving a white, newer model Chevrolet Suburban, and may possibly live in or frequent the 200 block of East Pastime Road, Dugan said.

Anyone with information is asked to call 911 or 88-CRIME.
