A male shooting victim in his 40s was found by emergency responders and taken to a local hospital with life-threatening injuries. He succumbed to those injuries three hours later.

Police told KCBS that a Toyota Matrix was shot up and just happened to be in the line of fire. It appeared that the car was being used as a place to live, but it was not clear if anyone was asleep inside at the time of the shooting.

According to police, the shooter used a high-powered firearm.

“Yeah, 40 calibers. Serious weaponry,” said SFPD Gang Task Force Officer Daniel Manny.

Police are calling the incident an active investigation and did not release any further details as of 12 p.m. Tuesday afternoon.
