It is being reported on August 23, 2015 that the two Oklahoma brothers, Robert Bever, 18, and Michael Bever, 16 may have uploaded a video of their attacks on Youtube. They stabbed their family members on July 22, 2015. Daniel, 12; Christopher, 7; Victoria, 5; and parents David, 52, and April, 44 were found dead on the scene. Their 13-year-old sister, Crystal, was injured but survived, while their other sister Autumn, 2, was unharmed.
The motive for the mass murder appears to be fame. The boys apparently wanted to become more infamous than the Columbine killers. Video cameras were found near the bodies leading police to believe that the boys recorded their violence. Authorities are still sifting through the many videos, pictures, and audio found on computers and thumb drives.
Their Youtube channel with multiple videos the boys made can be viewed here. The brothers have pleaded not guilty to all five counts of murder and are scheduled to appear in court on October 9, 2015.
