Earlier this month, Richards was arrested at a Target store in Van Nuys, Calif. after reportedly stealing over $600 worth of merchandize. Days later, according to an Us Weekly report, the former reality star was hospitalized.

Weeks later, after Richards reportedly checked into a treatment center in Orange County, Radar Online reported Richards had gone missing.

"Kim decided to leave,” an insider told the site regarding Richards' alleged exit from rehab. “She just bolted. The staff has no clue where she went, and it was definitely against medical advice.”

“Kim said she was cured, and felt good enough to go back to Los Angeles,” the source continued. “This is the worst thing Kim could do at this point because she has a court appearance this week for being drunk in public at the Beverly Hills Hotel. Kim is her own worst enemy. She is going to end up dead if she doesn’t get serious about this!”
