Who is Robert Bever?
His hair is disheveled, there's dirt on his face, and in his eyes, a calmness, and his mouth...
"Looked to me like he had a smirk on his face," said Corporal Leon Calhoun of the Broken Arrow police department.
Law enforcement sources say one of the siblings has given a full confession, stating that the murders were planned and that the killing wasn't supposed to end at the home. The confession, News Channel 8 has been told, was given matter of factly, with no hint of compassion or remorse.
"I don't know if there was any remorse or anything going on at this point," said Calhoun.
The homicides themselves, a brutal rampage of violence.
"I was told knives, there was a hatchet, there was several different types of weapons that were actually used in the homicides," said Calhoun.
"She said that he was very sweet, very kind."
And yet that is a description of the same Robert Bever known to Billie Paolini's daughter.
"Loved his family. Even walked to Walmart to buy them Christmas presents from here which is quite a ways," she said.
But nowhere near as far as the journey from loving son to murder suspect.
"I just don't know how if he's even comprehending what has happened or if he is really, is so removed that he cant feel remorse. It's unknown," said Calhoun.
