Eight people were shot, including one person who was killed, at a gas station in Oakland, California, Monday evening, according to police.

The incident occurred at a gas station at Seminary Avenue and MacArthur Boulevard at around 6 p.m. local time, the Oakland Police Department’s Kim Armstead said at a news conference.

Officers had responded to the scene to investigate a ShotSpotter activation and, upon their arrival, they learned of the shooting. Police did not find any victims when they arrived, but they did locate several casings.

“Shortly thereafter, our communications division received notification of multiple gunshot wound victims, who self-transported to local hospitals,” Armstead said.
