2 California police officers on trial in death of homeless man in 2011

Opening statements are underway in the trial of two California police officers charged in the death of a homeless man whose family says was schizophrenic.

Orange County District Attorney Tony Rackauckas (ruh-KAW'-kuhs) said Monday that Fullerton officers Manuel Ramos and Jay Cicinelli are responsible for the death of 37-year-old Kelly Thomas in July 2011.

Ramos has pleaded not guilty to second-degree murder and involuntary manslaughter. Cicinelli has pleaded not guilty to involuntary manslaughter and use of excessive force.

Thomas died five days after a violent confrontation with six officers who responded to a call about a man jiggling car door handles in a transit center parking lot.

The case fueled months of protests that led to the resignation of the police chief and a recall election in Fullerton.
