The people of Broken Arrow, Okla.—including seasoned investigators—are having trouble dealing with the horror that unfolded in a home in the Tulsa suburb late Wednesday night. Police say two teenagers arrested after five people were found dead in a home are brothers who are suspected of killing their parents and three younger siblings, NBC News reports. Robert Bever, 18, has been named as a suspect in the murder of his parents, David and April Bever, the Tulsa World reports. Bever and his 16-year-old brother are also suspected of killing their 12- and 7-year-old brothers and a 5-year-old sister. A 13-year-old sister was found critically injured in the home, while a 2-year-old was unharmed.
The brothers—who allegedly fled the home as police responded to a "silent" 911 call, possibly placed by the injured girl—are being held separately in the local jail pending transfer to Tulsa, the World reports. A police spokesman tells CNN that bladed weapons, including a hatchet, were found inside the home, "which would tell you that the scene was pretty gory." He says the killings in a "very middle-class" neighborhood are without precedent in the city's history. Neighbors tell the AP that the family's children appeared to be home-schooled and weren't allowed to play with other kids. "I'm shocked," a neighbor says. "I feel so bad for everyone who walks into that house. You can see it in the faces of the officers when they come out." (Read more Oklahoma stories.)
