Cupertino, Calif. – Authorities went door to door with guns drawn Wednesday in search of a disgruntled employee they say opened fire at a Northern California limestone quarry, killing three and injuring six before wounding another woman in an attempted carjacking.

Schools were on lockdown in the Silicon Valley city of Cupertino and nearby Los Gatos as SWAT teams sought Shareef Allman, 47, of San Jose.

Allman was at a routine safety meeting at the quarry at about 4:30 a.m. when he became disgruntled and left, authorities said. He then returned with a handgun and rifle and started shooting people, Santa Clara County Sheriff’s Lt. Rick Sung said. About 15 workers were at the meeting.
