The coroner’s office identified Kellie as the crash victim. The driver of the vehicle — later identified as Adams — fled on foot prior to officers arriving on scene. A search of the area failed to locate him.

Investigators have determined that there was a heated argument between Adams and another man. Adams then allegedly got into a vehicle and began driving southbound on Roberts Ave. The vehicle drove across the eastbound lanes of Roberts Ave. and slammed into Kellie.

Through their investigation, detectives identified Adams, a 53-year-old male from Santa Rosa, as the primary suspect. He is now wanted for homicide and attempt homicide.
