PLEASANTON (KTVU) -- Police said Monday that a Pleasanton man who was shot and killed by officers this weekend pointed a replica handgun at the officers before they opened fire.
The Alameda County District Attorney and Pleasanton police have launched separate investigations into the fatal shooting of Shannon Edward Estill, 58. He was pronounced dead at the scene.
Police were called to Estil's home in the 3200 block of Burgandy Drive shortly after 11:30 a.m. by the man's wife who said her husband was acting erratically. The woman, whose identity was not released, told police that she and her daughter had locked themselves into an upstairs bedroom because they feared for their safety.
When police arrived, they said they heard what sounded like a round being placed into a shotgun as officers were going into a side yard gate. Police said the man did not comply with their order to come out before the man opened a garage door and started walking down the driveway holding a fake gun.
Officer Keith Batt, a 17-year police veteran, fired his weapon, striking and killing Estill.
Batt began his career with the Oakland Police Department but moved to the Pleasanton department after he accused a group of senior Oakland officers known as "The Riders" of engaging in misconduct.
In 2000 Batt alleged that the four Oakland officers known as "The Riders" beat and framed suspected drug dealers in West Oakland and was the prosecution's star witness during two high-profile trials of three of the officers. The other officer fled the country and never stood trial.
But the officers weren't convicted of any charges in their two trials.
Police said no other injuries were reported from the incident.
Authorities said all of the officers involved in the incident were wearing and had activated their body-worn-camera systems when the incident occurred. The footage is now being reviewed as part of the internal probes.
Police Chief Spiller said in a written statement: "I extend my sympathy to the Estill family as any loss of life is tragic. I would also like to extend my support to our involved officers, their families, and the members of the Pleasanton Police Department."
