UPDATE: Bank Robbery Suspects Are San Pablo Brothers

The two suspects in Wednesday's deadly attempted robbery at a Wells Fargo Bank are brothers from San Pablo, and police are investigating whether they were involved in a previous robbery in Richmond, Pinole Police Chief John Hardester said late Wednesday.

Hardester did not name the suspects, citing protocol that family members of the man fatally killed first must be notified.

"We are investigating to see if there's a nexus," in the previous robbery that happened some months ago, Hardester said late Wednesday night.

The suspect who survived the incident is in critical condition, Hardester said.

A Pinole police officer and school resource officer is recovering from a gunshot wound to the shoulder sustained during gunfire exchange with men suspected of trying to rob an armored car at the bank. He is due to have surgery Thursday, Hardester said. A second officer at the scene shot and killed one of the suspect's Hardester said.

The driver of a Loomis Armored car sustained wounds to her stomach and to her left leg in a shootout with the suspects, Hardester said. She is in serious but stable condition as of Wednesday night.

The injured officer is a two-year veteran, the chief said. His name has not been released, and his injuries are not life-threatening.

Events began at 9:16 a.m., when police dispatch received calls from Wells Fargo Bank and from members of the public that two men had robbed the armored vehicle and had shot one of the Loomis security officers.

Initially, two Pinole police officers responded, and shortly after arriving encountered one of the suspects near the bank. One of the police officers shot a suspect, killing him.

Hardester said that shots were fired both near the armored car which was in front of the bank, and on the street, behind the building.

Within minutes of the shooting, law enforcement officers from multiple areas sped to the scene. They included officers from Hercules, Richmond, Moraga and Pleasant Hill police departments and from Contra Costa County Sheriffs and California Highway Patrol.

Police arrested the second suspect at a hospital, where he had gone with gunshot wounds that likely occurred when one of the Loomis guards returned fire on him, the news release said.

Identities of the responding officers, suspects and security guards have been publicly released.

Police cordoned off a stretch of Fitzgerald Drive, near the scene of the incident, until about 5 p.m. where the robbery attempt occurred, say employees who have tried to get to work at Target and Staples. The also blocked access to businesses in a strip mall across Fitzgerald Drive, including the In-and-Out and Outback restaurants.

By 5:30 p.m. the cordoned off area was limited to the area around the bank.

An investigation is being conducted by Pinole and Richmond police, as well as the Contra Costa District Attorney.
