Shareef Allman, the man suspected of opening fire in a Cupertino, California limestone quarry, was shot and killed by police Thursday morning in a Silicon Valley neighborhood after a daylong manhunt.

Mountain View police that confirmed that Allman, 47, was the man killed.

According to authorities, Allman became upset Wednesday during a safety meeting at Permanente Quarry, which is owned by Lehigh Hanson. Allman left the meeting, came back with a handgun and rifle, and started firing.

15 workers were at the meeting. Three were killed, and six were wounded.

Laurie Smith, Santa Clara County Sheriff, released the names of the dead last night as Manuel Pinon, 48, of Newman, Calif., and John Vallejos, 51 and Mark Munoz, 59, both of San Jose.

After an attempted carjacking to evade police, Allman fled from the quarry on foot. Schools were locked down in Cupertino, home of Apple Inc., and authorities went door to door as residents were warned to stay indoors and to call police if they saw any suspicious activity.

Jenny Martin, who lives nearby, told CBS that authorities had scoured neighborhood Wednesday in search of Allman. We were in the house lockdown all day yesterday, Martin said. The SWAT stormed in like ninjas, and they took a position in our front bedroom.

Authorities found Allman's car around 7:30 a.m. this morning. They collected a shotgun, a handgun, and two rifles believed to belong to the suspect.

Soon after, neighbors heard gunfire, and Allman's tarp-covered body was set on a nearby driveway, remaining there for hours after the police confrontation. Authorities cordoned off the streets surrounding the scene, and the body was eventually removed.

Community in Shock

Those closest to Allman are incredulous. Many remember him as a big man with a big smile, a single father whose devotion to his daughter was striking to all those who knew him. He worked tirelessly in the aftermath of Hurricane Katrina to raise money for the disaster's victims, and wrote a novel about the evils of domestic violence.

You talk about Mr. Mom, said Sandra Dailey, 54, who described herself as a close friend. He never missed an event. He was an incredible father.

He always had a big smile on his face, Paulette Conner, 57, told TIME. Connor is a neighbor at Allman's San Jose apartment complex who said she's known him for five years. I've never known him to have any violent tendencies, she repeated. Never. Ever.
