p.m. on Wednesday, July 22, 2015, a call came in 911 dispatch in Broken Arrow, Oklahoma. The operator heard screaming and sounds of struggle in the background before a young boy's voice saying that somebody was attacking his family. Before getting any more information about what was happening, the call ended after more inaudible screams as someone clearly took the phone from the original caller. The operator searched the number and was able to track the address, but after a failed attempt to contact the owner of the house, David Bever, officers were dispatched to the scene at 709 Magnolia Ct. Upon arriving, they saw an alarming amount of blood on the front porch. As the officers knocked on the door, they heard a girl's voice inside, screaming for help. Once they forced their way in, the officers found a 13-year-old girl, Crystal Bever, who had been stabbed repeatedly and her throat slit but was still somehow alive. After moving Crystal outside to safety, officers returned to investigate the rest of the house. What they found was straight out of a horror movie.
