The Bever brothers, charged in the murders of their parents and siblings, were arraigned in Tulsa County court Monday. Public defenders entered not guilty pleas on behalf of Robert and Michael Bever who are each charged with five counts of first-degree murder.
A preliminary hearing was set for 1:30 p.m. October 28, 2015. That date is subject to change.
Prosecutors have also charged the brothers with assault and battery with intent to kill after their 13-year-old sister survived the attack in a Broken Arrow home July 22, 2015.
Detectives say the brothers acted together when they killed their parents, David and April Bever, and their siblings Daniel, Christopher and Victoria.
The boys were brought into a video arraignment with hands cuffed in the front. One was wearing an orange jumpsuit; the other appeared to be wearing a black or navy jumpsuit.
It appeared they were brought in and removed separately from the other inmates.
Rob Nigh is representing Michael Bever, and Cheryl Ramsey is Robert's defense attorney. They asked the judge to tell the boys they would visit them soon.
Neither attorney would comment after the arraignment, saying it was too early in the process.
A judge is expected to decide Thursday whether to grant a defense motion to seal all the documents in this case.
