A man struck by a driver as he walked on a San Francisco freeway was suffering from a gunshot wound, police say, turning the investigation of his death from a typical traffic collision endeavor to that of a "suspicious death."

The 42-year-old man was walking above Division and Ninth Streets on the Interstate 80 westbound connector to northbound Highway 101 at around 5 a.m. Thursday, California Highway Patrol spokesperson Officer Vu Williams tells Bay City News.

The man, who as of Friday morning had yet to be publicly identified by the San Francisco Medical Examiner's Office, was struck by the driver of a gray 1997 Ford Ranger. He was transported to San Francisco General Hospital, where he succumbed to his injuries.

“He suffered from pretty extensive injuries from being struck,” Williams told the Ex, but that wasn't all, as SF General staffers also discovered a fresh gunshot wound in the man's leg.

That's when CHP called in the San Francisco Police Department, reports the Chron, which will be taking over the investigation in an effort to determine the circumstances of the shooting. Police believe that the man was shot before he got on the freeway, BCN reports, but "the exact location has not been determined."

The effort is now "a suspicious death investigation,” SFPD spokesperson Officer Giselle Talkoff told the Chron, saying that police await autopsy results to determine of it was the bullet or the collision that caused the man's demise.

The driver who struck the man was on his way to work when the collision occurred, BCN reports. According to the Chron, he "remained on scene and cooperated with police. There was no evidence of drugs or alcohol in his system and he was released."
