The coroner is trying to identify a skull and bones found near an abandoned marijuana grove in a rugged Santa Monica Mountains area near Malibu.
Los Angeles County sheriff's spokesman Steve Whitmore says the bones were removed from a Monte Nido area ravine Monday night and it could take weeks to identify the remains.
Whitmore cautioned against linking the discovery to the disappearance of Mitrice Richardson, who vanished after being released from sheriff's custody last September.
Richardson's family and a family concerned about a relative who went missing in the area several years ago went to the Malibu-Lost Hills sheriff's station Monday night and met with coroner assistant chief Ed Winter.
