Investigators are combing hotels and casinos along the Las Vegas strip in search of a 25-year-old Southern California woman who vanished after she was released from custody for not paying a bill for a meal.

Mitrice Richardson

Mitrice Richardson, a former beauty pageant contestant, was arrested last September at a restaurant in Malibu, California, because she did not have money to settle her check at Geoffrey’s, an upscale restaurant.

She was brought to the Lost Hills/Malibu sheriff’s station and was later released without her car, which held her purse and other belongings.

It was later discovered that Richardson may have had an episode of bipolar disorder. Mitrice’s mother, Latice Sutton, and her father, Michael Richardson, have both filed lawsuits against the Los Angeles County Sheriff’s Department for its handling of her arrest and release.

Authorities are investigating reports of multiple sightings in Las Vegas. Richardson’s father says he saw Mitrice walking down a street but could not catch up to her and a former high school classmate says he saw her at a bar.
