People in the quiet Tulsa suburb of Broken Arrow are struggling to make sense of the horrors discovered in a gray barn-like house where five members of a family were found stabbed to death and a sixth was wounded but alive.

What is more shocking to locals is that two teenage sons in the family are expected to be charged in the deaths. A ninth family member, a 2-year-old girl, was found unharmed and was transferred to state custody.

Police identified one of the suspects as 18-year-old Robert Bever, who was apprehended along with his 16-year-old brother, whose name was not released because he is a juvenile. The dead parents were identified as David Bever, 52, and April Bever, 44. The dead and wounded children were not identified.
