September 2007: Richards filed documents seeking "the assistance of the court to obtain orders to protect her children" from Sheen. She accused Sheen of "an attraction to underage women," providing numerous printouts of porn websites he allegedly visited during their marriage. Sheen lashed out at Richards in response, saying she "behaves as though she owns our children. She does not. A day of legal reckoning for her is fast approaching."
December 2009: Sheen was arrested Christmas morning after his then-wife Mueller told police he had threatened her with a knife. Three months later, he was charged with two misdemeanors -- felony menacing and assault and criminal mischief. He entered court-ordered rehab.
August 2010: As a part of a plea bargain for his December '09 arrest, Sheen pleaded guilty to misdemeanor assault in exchange for having the rest of the charges against him dismissed. He was sentenced to 30 days in rehab, 30 days of probation, 36 hours of anger management, and barred from possessing guns for the rest of his life.
October 2010: Sheen was hospitalized after reportedly going on a drunken rampage through New York City's Plaza Hotel, causing several thousand dollars' damage to his suite. According to the NYPD, Sheen also admitted to doing cocaine. Capri Anderson, the adult film star who partied with Sheen, claimed she hid in a closet because she was afraid of him. She later filed a criminal complaint saying she had been assaulted and harassed. No arrest was made.
March 2011: Mueller got a restraining order against Sheen after she claimed he threatened to cut her head off, put it in a box and send it to her mother. Police transported Sheen's sons from his Beverly Hills mansion to Mueller, whose whereabouts remain unknown.
