Two brothers in the Tulsa, Oklahoma suburb of Broken Arrow are accused of stabbing to death both their parents and three of their siblings. A 13-year-old girl, one of two victims who survived, made the silent 911 call that alerted authorities to the quintuple homicide. Robert Bever, 18, and his 16-year-old brother who has not been publicly identified, were tracked by police dogs to a wooded area behind the house and arrested. The victims were identified as David Bever, 62, April Bever, 44, and a 5-year-old girl, a 7-year-old boy, and a 12-year-old boy. A 2-year-old girl was found unharmed and is now in state custody.
