L.A. detectives receive Gibson audio recordings

LOS ANGELES -- A Los Angeles County sheriff's spokesman says detectives investigating Mel Gibson have received audio recordings from a court hearing the actor's child custody matter.

Sheriff's spokesman Steve Whitmore says detectives received the recordings Thursday morning after a court hearing. Several sheriff's detectives were spotted outside a closed hearing where Gibson's criminal attorney and attorneys for his ex-girlfriend appeared.

All of the attorneys declined comment. The sheriff's department is investigating whether the Academy Award-winner abused his ex-girlfriend, Russian singer Oksana Grigorieva, in January.

Whitmore says the detectives received CDs, but did not know how many recordings were on them. He says detectives will now work to authenticate the recordings for a possible criminal case.
