Mitrice Richardson is the South L.A. substitute teacher who has been listed as missing since leaving the sheriff's station on the Valley side of Malibu Canyon on Sept. 17, following a strange night at Geoffrey's in Malibu. This weekend, activist and writer Earl Ofari Hutchinson said there have been reported sightings of Richardson in the city. From the L.A. Wave:

Several South Los Angeles residents have said they saw Richardson...at Manchester Avenue and Denker Street, Manchester and Western avenues and Florence and Western avenues, he said.

However, none of those reports were relayed to authorities, said Officer Bruce Borihanh of the LAPD Media Relations Section.

"That's the problem," Hutchinson said. "People are seeing her and no one has had the presence of mind to notify authorities."

Searches were conducted in and around Malibu Canyon after Richardson, whose Honda had been impounded, walked away from the Lost Hills station. Her parents say that mental issues may have accounted for her getting in trouble at Geoffrey's, but the sheriffs say she was fine when she left custody. There is a $10,000 reward out from the county Board of Supervisors.
