SANTA ANA, Calif. (AP) — The scandal-plagued Orange County Sheriff's Department is investigating whether jail staff used a Taser stun gun on a cat that was found dead on facility grounds.

The investigation comes after a scathing criminal grand jury report last week that found deputies at Theo Lacy Jail sent personal text messages and watched TV while inmates beat a fellow inmate to death.

Sheriff's spokesman John McDonald says a tipster told the department Monday that jail personnel used a Taser on the cat. The animal was later found dead on the jail grounds, between two fences.
