BROKEN ARROW, Okla. – Authorities say two Oklahoma teenagers have been officially charged with murdering five of their family members in a brutal attack last week.

On July 22, Broken Arrow police were called to a home after a disturbing 911 call was made by a young boy.

When officers arrived, they stumbled upon a horrific scene.

They found a 13-year-old girl suffering from multiple stab wounds. Despite being critically injured, the girl told police that her eldest brothers had attacked her family.

Authorities discovered the bodies of 52-year-old David Bever, 44-year-old April Bever, a 5-year-old girl, a 7-year-old boy and a 12-year-old boy.

All of the victims were stabbed to death.

“I was told knives, there was a hatchet, there was several different types of weapons that were actually used in the homicides,” said Cpl. Leon Calhoun, with the Broken Arrow Police Department.

Officials also found a 2-year-old girl, who was unharmed, inside the home.

Officers found fresh footprints, and eventually arrested 16-year-old Michael Bever and 18-year-old Robert Bever for the crimes.

Law enforcement sources told KTUL that one of the boys has provided a full confession.

“I don’t know if there was any remorse or anything going on at this point,” said Cpl. Leon Calhoun, with the Broken Arrow Police Department.
