OC District Attorney Continues Probe Into Homeless Man's Beating Death

FULLERTON (CBS) — The Orange County District Attorney is halfway through his investigation into the death of 37-year-old Kelly Thomas.

Tony Rackauckas' office is looking into whether six Fullerton police officers used excessive force when they arrested Thomas at a bus depot on July 5.

Thomas, who suffered from schizophrenia, died five days after his arrest.

Rackauckas' office has talked to 100 witnesses so far, but investigators are still waiting for a toxicology report.

The Fullerton City Council also approved a contract to hire independent investigator Michael Gennaco.

Fullerton's police chief, Michael Sellers, was placed on paid medical leave shortly after Thomas' death.
