Still No Trace of Mitrice Richardson

Malibu (myFOXla.com) - Friends and family of a South Los Angeles woman who went missing after being released from the Malibu-Lost Hills sheriff's station rallied at the sheriff's station today.

Mitrice Richardson, 24, was arrested Sept. 16 at Geoffrey's restaurant in Malibu, where she was acting strangely and was unable to pay her $89 bill.

Sheriff's deputies also found a small amount of marijuana in her car, and the Cal State Fullerton graduate, who passed a sobriety test, was booked at the sheriff's station and then released about 1:25 a.m., according to the sheriff's department.

Her 1990 Honda Civic was impounded, and she walked away from the station with no cell phone.

A homeowner on Cold Canyon Road reported a woman resting in her yard about 6:30 a.m., but when deputies arrived, the woman was gone.

Her father, Michael Richardson, organized today's rally hoping to get authorities to do more to find his daughter, whom he believes may be having mental problems. He has also set up a Web site at www.findmitrice.info .

Two searches were conducted in the area stretching from Calabasas to the coast over consecutive weekends, but Richardson was not found, despite reports that she had been spotted everywhere from Los Angeles to Orange County and as far away as San Jose.

The Los Angeles County Board of Supervisors is offering a $10,000 reward for information on Richardson's whereabouts.

The missing woman's mother told the Orange County Register she believed her daughter was in a "manic state of mind" because she was sending "erratic" text messages to family and friends the afternoon of Sept. 16.

But sheriff's spokesperson Steve Whitmore had said there was no reason to hold Richardson because she did not appear to be mentally ill or intoxicated and signed several release forms.

Richardson is black, 5 feet 5 inches and about 125 pounds with tattoos on her lower abdomen and behind her neck. She was last seen wearing a brown Bob Marley T-shirt and blue jeans.

Anyone with information about her whereabouts was asked to call Los Angeles police at (213) 485-2531.
