LIVERMORE — Police are investigating a shooting in the parking lot of a store Saturday evening that left one person dead and another injured.

At 6:05 p.m., Livermore police received several calls of a shooting in the parking lot of the CVS Pharmacy at 1500 First St. When they arrived, they discovered two men inside a vehicle. Both had been shot, police said. Neither has been identified.

The driver was pronounced dead at the scene. The front-seat passenger had multiple gunshot wounds and was taken to a hospital; his condition was not known as of late Saturday.

Witnesses at the scene described the getaway car as a black BMW with the license plate 5PLR682 and red racing stripes on the hood. They described the driver as a black man with a tall, thin build, wearing a beanie cap and armed with a black, long gun. There was no detailed description of the second suspect, but police believe it is a man, said Livermore police Sgt. Steve Goard.

Witnesses told police that the BMW drove out of the CVS parking lot onto Railroad Avenue. The California Highway Patrol spotted the BMW on westbound Interstate 580 in the San Leandro area and initiated a pursuit that led to Oakland, where police lost sight of the vehicle, Goard said.

Jess Hutchins, of San Jose, was in the Safeway store near the CVS, buying sandwiches on his way to see “Jekyll & Hyde — the Musical” at the Bankhead Theater ﻿when he saw a man running inside, shouting, “There are two people shooting at each other! Call the police!”

“Then he said, ‘Look! Their taillights are leaving,’ ” Hutchins added.

Interestingly, Hutchins said, “some people seemed startled, but others not — like it was a false fire alarm.”

The Livermore Police Department is asking for the community’s help. Anyone who sees the suspect vehicle is asked to call 911 and to consider the occupants to be armed and dangerous. Witnesses and anyone with information about the shooting are asked to call the Livermore Police Department-Public Information Officer line at 925-371-4777.
