SUNNYVALE, Calif. (AP) — Authorities say three Northern California sheriff's deputies shot and killed a man believed to be the suspect in a deadly quarry shooting.

Santa Clara County Sheriff Laurie Smith says investigators believe the man is 47-year-old Shareef Allman, but the coroner will have to confirm the identity.

Smith says three deputies were on routine patrol in a Sunnyvale neighborhood Thursday morning when they encountered a man crouched behind a vehicle in the driveway of a home. He matched Allman's description.

Smith says the deputies opened fire after the man displayed a handgun.

The fatal confrontation happened in the same neighborhood that authorities had scoured a day earlier in search of Allman. He's accused of opening fire during an early-morning meeting at Permanente Quarry in Cupertino, killing three co-workers and wounding six.
