TULSA - Two Oklahoma teenagers appeared in court Tuesday to face accusation they stabbed their parents and three siblings to death in a rampage last summer.
During Tuesday's preliminary hearing, the court found probable cause. The Bever brothers will now appear in district court for an arraignment on Monday morning.
Two Broken Arrow detectives took the stand in Tuesday's court appearance. The first detective, Chane Cothran, recalled the interview with the 13-year-old who survived.
She said her brothers were interested in mass killings for at least a year before the killings. She also recalled seeing knives and body armor on the bed of the boys the night of the killings.

She heard the brothers say they needed to get her back into the room. That is when the attacks began with a knife to her throat according to the girl.
She was able to get away and said she went outside in hopes of setting off the home's alarm. She made it to a bench and knocked it over on herself.
Michael Bever told a detective he wanted to kill the family and steal their money.
The second detective, Eric Bentz, recalled an interview with Robert Bever. Bentz said Robert laughed and joked during the interview and waived his right to an attorney. Robert said he first thought of the plan to kill his family when he was 13-years-old.
He said he got a job to save enough money to buy the items needed to carry out the killings. He also said he worked long enough to save up the money needed to buy their body armor and weapons.
The boys moved the attack up when Robert realized some of the ammo he ordered would arrive at the home.
They planned to go room by room through the house starting at midnight. A pistol and two handguns were ready for pickup at a gun store the day after the attack.
They said they planned to go to Walmart, buy bins and go home to clean up the blood and store the dead family members in the bins in the attic.
The brothers also planned on making two videos. One for law enforcement explaining what the did, and one "G-rated" video to upload to YouTube.
They had 2,000 rounds of ammo for the pistols and 250 rounds for the shot gun.
The brothers said they planned to steal a car from their parents and drive to populated places and kill 5 people everywhere they stopped. They wanted to kill as many people as possible.
