Law Enforcement Going Door-to-Door, Searching Backyards for Shooting Suspect

As an armored tank patrols streets, armed officers and dogs are going door-to-door in a Sunnyvale neighborhood near Wolfe and Homestead roads searching for the suspect in this morning's shootings at Lehigh Southwest Cement Plant in Cupertino.

A large contingent of regional law enforcement including the U.S. Marshals and the FBI, are a part of the manhunt for Shareef Allman, 47, who Santa Clara County Sheriff's Deputies believe shot and killed three people at the cement plant, wounded six more, and then later shot and attempted to carjack a woman near Homestead Road and Tantau Avenue.

Tonight officers are knocking on doors near the intersection of Inverness Way and Nuthatch Lane and entering backyards with weapons drawn. If people are at home, the officers are entering houses to search.

Allman is believed to have escaped on foot after the attempted carjacking and shooting of a woman. Her injuries are not life threatening, Sheriff Laurie Smith told reporters earlier today.

A massive manhunt along the borders of Cupertino, Sunnyvale and Santa Clara followed and continues tonight.

Smith said Allman is believed to be armed and dangerous. He is described as black, 5'11", 215 pounds, with a light beard.

She said they believe a hand gun and assault rifle were used in the attacks; officers later recovered some weapons in the area near the carjacking. Deputies confirmed he has weapons registered in his name.

Anyone with noticing suspicious activity in the area is encouraged to call 911. Citizens with any information about Allman should contact the Sheriff's non-emergency line at (408) 808-4500.

For residents who cannot return home due to the search a Red Cross shelter is now open at the Sunnyvale Senior Center from 6 pm for Sunnyvale and Cupertino residents. The address of Sunnyvale Senior Center is 550 East Remington Drive, Sunnyvale; phone number is (408) 730-7360.
