At 9:30 a.m. on May 11, 1992, six LASD narcotic team deputies served a warrant on a mobile home in Palmdale suspected as a site of methamphetamine sales. As part of the entry plan, Deputy Richard B. Hammack was to approach the front door and knock. Other deputies hiding in nearby bushes were then to run inside when the door opened. The plan began to fall apart when a woman exited the house and began wrestling with the deputies. Gunshots then began pouring out at them from inside the house.
The deputies returned fire and rushed inside. The gunfire was intense, and deputies retreated as one of their number received a minor injury when his flashlight was shot out of his hand. When they got outside they realized Deputy Hammack was not with them. They reentered the mobile home and discovered him collapsed on the floor near the door to a bedroom with bullet wounds to his neck, face and upper body. They rushed him via radio car to nearby Palmdale Hospital Medical Center, but he died shortly after arriving.
The suspect was found shot to death in a bedroom. The woman who struggled with the deputies as they attempted to make entry was his wife. Also in the house at the time of the shooting were her elderly father and two small children. They escaped injury. She initially faced a murder charge, but this was later dropped. In February 1993, she pleaded no contest to a charge of resisting arrest and received a two-year prison sentence.
Deputy Hammack, 31, was a seven-and-a-half-year veteran of the Sheriff’s Department.
An avid hockey player and motorcycle enthusiast, he was born in Bakersfield and was a long-time resident of the Antelope Valley. Hammack was to be married the following month to Tammy Zeiner. At the time of the shooting, she was at a hospital in the San Fernando Valley having an ultrasound performed to learn the sex of their un-born child. The couple’s son, also named Richard, was born later in 1992.
