CUPERTINO - A disgruntled worker opened fire on Wednesday at a Northern California cement plant and quarry, killing two people and injuring six, police said.
The gunman, identified as Shareef Allman, was also suspected of shooting a woman contract worker for Hewlett Packard during an attempted carjacking a short time later, Santa Clara County Sheriff's spokesman Sgt. Jose Cardoza said.
Witnesses told detectives that authorities were looking for a man matching Allman's description who ran from the second shooting, Cardoza said.
"We believe him to still be in the area. Several tactical teams are conducting yard-to-yard searches," he said.
Witnesses told police that Allman had arrived at a safety meeting at the Lehigh Southwest Cement Permanente Plant in Cupertino at about 4:30 a.m. armed with a handgun and rifle, and opened fire on his co-workers, Cardoza said.
Witnesses and victims said Allman, in his 40s, shot eight people within two minutes before fleeing in a dark colored vehicle, Cardoza said.
