“I am alive so must live,” Creigh Deeds tweeted on Friday. “Some wounds won’t heal. Your prayers and your friendship are important to me.” The Virginia state senator had just been released from the University of Virginia Medical Center in Charlottesville, four days after his 24-year-old son Gus stabbed him and then shot himself dead. The two were at the family’s western Virginia farm when the attack—likely “an attempted murder/suicide,” investigators say—occurred on Tuesday. Gus, one of Deeds’ four children from his first marriage, reportedly suffered from mental-health issues and was apparently turned away from a psychiatric hospital on Monday, despite an emergency custody order, because of a lack of beds.
