Oklahoma signee Justin Chaisson, who faces criminal charges, was back in a Las Vegas courtroom last week, appearing on a charge of violating a restraining order filed by his ex-girlfriend. But because no representative for the plaintiff showed, the judge threw out the case, according to the Las Vegas Sun. Chaisson’s 17-year-old ex-girlfriend successfully obtained the restraining order March 16, court spokesman Michael Sommemeyer said. The next day, Chaisson allegedly attacked his ex-girlfriend by forcing her into his car and threatening to kill her with a screwdriver, resulting in three felony charges: assault with a deadly weapon, false imprisonment and coercion. He also faces a gross misdemeanor charge of false imprisonment and a misdemeanor charge of battery constituting domestic violence. Chaisson is scheduled to return to court on April 29 for a preliminary hearing on those charges.
