Arraignment is being delayed for two teenage brothers on first-degree murder charges in the stabbing deaths of their parents and three siblings at the family's home in Broken Arrow.
Court records show Monday's scheduled arraignment in Tulsa County District Court for 19-year-old Robert Bever and 17-year-old Michael Bever has been postponed until May 2. Defense attorneys requested the delay and prosecutors did not object.
The brothers have pleaded not guilty in the July stabbings of their parents, David and April Bever, their 12- and 7-year-old brothers Daniel and Christopher, and 5-year-old sister Victoria. Two other siblings survived.
Detectives testified during a preliminary hearing that the brothers detailed a plot to carry out mass killings and that Robert Bever expressed a desire for notoriety for being a serial killer.
