WHITTIER — A South Whittier man has begun serving a 12-year prison sentence for stabbing wife to death at their home in an unincorporated county area near Whittier.

Andres Zazueta, 47, was sentenced to prison Feb. 3 after pleading no contest to voluntary manslaughter in the death of 45-year-old Maria Guzman on March 13, Los Angeles County District Attorney’s Office spokeswoman Jane Robison said.

Originally charged with murder, Zazueta attacked his wife with a kitchen knife at their home in the 10700 block of Carmenita Road, then wounded himself as well before deputies arrived at the scene, officials said.

Guzman died at the scene, while Zazueta was hospitalized for his injuries before being arrested.

Other than domestic violence, a motive in the killing has not been released.
