Peter Van Sant and 48 HOURS investigate the death of a college cheerleader and the case against her boyfriend Mark Howerton, in an encore of "The Final Hours of Cayley Mandadi" to be broadcast Saturday, June 12 (10:00 PM, ET/PT) on the CBS Television Network. 48 HOURS takes viewers inside a case that left a family struggling to find out what happened to the young woman and the debate that continues today over the cause of her fatal injuries. Mandadi, 19, was last seen alive at a San Antonio music festival with Howerton, 22, on Oct. 29, 2017. Howerton told police that the couple took party drugs and had consensual sex. At some point, Mandadi stopped breathing. He said he rushed her to the nearest hospital, where medical teams tried to save her. Mandadi was declared brain-dead and taken off life support. Investigators believed the injuries pointed to murder. The medical examiner ruled that she died of blunt force trauma to the face and head. Howerton was arrested on Feb. 28, 2018 and charged with sexual assault, murder and later with kidnapping. Prosecutors thought it was an open-and-shut case, though it would prove anything but. What happened when the case went to trial left onlookers stunned.
