This not only affected me physically, having to deal with the repercussions of the incident, butalso mentally from the anxiety that came along with it."According to the report, one of the roommates also reported getting a threatening text message from an apparent ally of King's. "While Hayley is moving out don't [expletive] with her. Y'all have been [expletive] taunting her since the semester started. If she tells me you're [expletive] with her I will personally come and check you. You too old to try to be bullying some damn body. Grow the [expletive] up," a portion of the text message stated.King was released a day after her arrest on a $5,000 personal recognizance bond.King's attorney declined to comment on the case.Her next court appearance is scheduled for May 4.
