According to testimony at the hearing, detectives say that Robert Bever wanted "to have some sort of fame or notoriety for being a serial killer."

The Tulsa World reports that Robert described killing as "a hobby," adding that they didn't plan to stop with just five of their family members.

The boys' 2-year-old sister was found unharmed in the home, but investigators say their plan to kill her was interrupted.

A detective claimed that Robert Bever said he was planning on cutting off his 2-year-old sister's head with an axe. Robert also told detectives that Michael coerced their siblings out of locked rooms during the attack by pretending he was in danger.

KJRH says a detective testified that Robert Bever told him that he first started planning the murders of his family when he was 13-years-old.

He said he got a job and saved money to purchase weapons online, so checks to confirm he was an adult wouldn't be performed.

The boys said they moved the attack up when Robert realized some of the ammunition was being sent to his home.

After killing everyone in the home, they planned to purchase bins and store their dead family members in the attic.

Investigators say they also planned to make two videos; one for law enforcement and one for YouTube.

After the initial crimes were complete, the brothers planned to steal their parents' car and drive to populated places and kill five people everywhere they stopped.

During Tuesday's hearing, the defense claimed that the boys' father would throw them and verbally abuse them.

The pair is charged with five counts of first-degree murder and one count of assault and battery with intent to kill.
