Last summer, what was first reported as an "open line" phone call led to the discovery of five bodies and a critically injured child at a Broken Arrow home. A toddler was found unharmed, and two teenage boys were located hiding behind the home.

The dead were identified as five members of the Bever family, and the call formerly reported as an open line call was determined to be a call from a 12-year-old boy who was subsequently killed in the attack.  That boy's phone call is credited for saving the life of two of his sisters, then aged 13 and 2. 

The two boys hiding behind the family home, Robert Bever, then 18, and Michael Bever, then 16, were accused of attacking and killing their mother, father, and three siblings, aged 12, 7, and 5. A 13-year-old sister survived the attack, and police say the pair had planned to kill the toddler, but were interrupted by the arrival of police before they were able to injure her.

Reports say the teens admitted to killing their family and say the attack was just the beginning of what they had planned to be a killing spree that would have moved beyond the walls of the family home and into the community. Robert Bever reportedly told investigators that the pair planned to store their family members' bodies in the attic before stealing their father's car, driving to populated areas, and killing at least five people everywhere they stopped. An investigator says the eldest Bever brother said he had been planning the killings for nearly five years--since he was 13 years old.

Both Bever brothers are charged as adults with five counts of first degree murder and one count of assault and battery with intent to kill.

Now, jail records show that last month, Robert Bever, now 19, attempted to kill himself at the Tulsa County Jail. On June 17, during a routine check, jail staff found Robert hanging from a sheet tied to his "sleeping boat," a tray-type cot for inmates without a bed. Reports say Robert propped the boat up against a toilet and attempted to suspend himself by the neck from the top of the boat. Jail workers cut the teen down and determined his efforts left him uninjured. They placed the teen under suicide watch.

The Bever brothers are scheduled for arraignment in Tulsa County District Court on Monday, July 11.
