Oklahoma girl, 13, reportedly named brothers as assailants who fatally stabbed parents, 3 sibilngs

Fox 23 said investigators are looking into a shipment of ammo that was supposed to be delivered to the home Thursday.



Police haven’t established a motive for the killings.

Calhoun said Friday investigators were scouring social media posts they believe belong to Robert Bever. Those accounts include a Pinterest and Facebook account.

His Pinterest account paints a picture of Bever’s interest in Star Wars, the rock band Linkin Park and sports cars. A Facebook post lists him as a recent graduate of Citizens' High School, which describes itself as providing "a home-school curriculum" for people hoping to earn a college degree.

Neighbors of the Bevers say the family mostly kept out of sight and to themselves – the kids played alone in the backyard, walked down the streets bunched together and their parents didn’t socialize much. That appeared to carry over to the father’s work

David Bever’s former co-workers in the IT department at Samson Resources described him as a quiet man who kept to himself.

"He was a nice guy, but we weren't close," said Lisa Wolfe, Bever's supervisor at Samson. "I hired him. He worked for us for several years as a contractor. He was a good worker and a nice guy. He didn't get involved in any office politics, and those are the kind of people I like to work with.
