Antioch police said the pair were arrested late Wednesday following the incident at a CVS pharmacy inside Target, 5769 Lone Tree Way, at Slatten Ranch shopping center.
In a statement, police said officers responded to the store at 2:02 p.m. for a report of an armed robbery, and learned en route to the store that someone had been shot there.
Officers found and detained two men, identified as Ramon Meza-Morales, 18, and Raul Garcia, 18, as they tried to flee in a vehicle. The men were arrested on suspicion of armed robbery and assault with a deadly weapon, and booked into Martinez county jail.
A crashed black Mercedes was seen outside the store in its parking lot, but police did not provide details on its connection.
Contra Costa County Fire Protection Department firefighters responded to the scene for a medical emergency at 2:08 p.m. and headed to the store’s pharmacy area, ConFire PIO Steve Hill said.
One man was treated for a single gunshot wound to the leg and transported by ambulance to John Muir Medical Center, Hill said. Antioch police did not identify the victim, but later said his injuries were non-life-threatening and no other injuries were reported.
John Foehr, a store customer, said he was about 50 feet away from the scene in the personal care department when he heard shots fired and smelled gun residue, but did not see what happened because his view was blocked.
“I heard three gunshots fired and a scream — there was a brief head of smoke, you could smell a little bit — and at that point, I started moving toward the rear of the store,” Foehr said. “And the guy in front of me hit the emergency (exit lever) and people started piling out.”
Foehr said that after exiting he made his way toward the front of the store to see if he could help anyone. He said he saw a woman, whom he thought was a nurse, applying a tourniquet to a man’s leg in front of the store.
Police at the scene searched the store and escorted customers outside, Foehr said.
Foehr said he helped calm down a hysterical elderly woman who was sitting down and screaming by talking with her and holding her hand.
“(It seemed) every cop in Northern California was there,” Foerhr said. “It was definitely surreal.”
Other customers at the store posted on social media described the scene as “terrifying.”
