Two brothers fatally stabbed their parents and three siblings Wednesday night at a home in Broken Arrow, Oklahoma, and critically injured a fourth sibling, police said.
The brothers, Robert Bever, 18, and his brother, 16, whose name hasn’t been released, were arrested.
The victims and suspects all lived in the same Broken Arrow home. A 2-year-old sibling was in the house at the time of the killings, but was not harmed.
Here’s what you need to know:
1. Police Went to the Home After a Silent 911 Call
Police told NBC News that they responded to the home in the 700 block of Magnolia Court at about 11:30 p.m. after receiving a silent 911 call. The officers found the five victims dead when they arrived.
Police say the two teen sons, ages 18 and 16, fatally stabbed their parents, April and David Bever, and three siblings, ages 12, 7 and 5, who have not yet been identified.
A living juvenile victim, a 13-year-old girl was taken to the hospital in critical condition with multiple stab wounds. She was in stable condition after surgery, the Tulsa World reports. Another family member, a 2-year-old child, was found unharmed.
Police believe the 13-year-old girl called 911 after the stabbings, but was not able to speak to the dispatchers.
2. The Suspects Were Tracked to a Wooded Area
The two teenage suspects were found in a wooded area near the home, police told News on 6. They ran out of the home and were tracked down by a police K-9.
“It appears that the two suspects fled out the door sometime during our arrival. We had a canine track and they were apprehended,” police Sergeant Thomas Cooper told the Associated Press.

Police spokesman Sergeant Thomas Cooper told NBC News that the crime is almost “unprecedented” in the community of 100,000, which he called a “relatively safe community, smaller than Tulsa,” that could be called a “bedroom community.”
“The crime scene has taken a pretty heavy toll on officers who have come out here,” Cooper said. “It hits close to home, especially when the victims are adults and juveniles. Our officers have a lot to take in.”
Broken Arrow Corporal Leon Calhoun told the Associated Press, “I’ve been here 19 years and I don’t know if we’ve had more than three homicides in a year. I don’t think we’ve had a single incident of this magnitude.”
4. Neighbors Say 2 Adults & Several Children Live at the Home
Neighbors told The Associated Press that two adults and several children lived at the home, one of the larger and more expensive homes on the block. The children were homeschooled, neighbors said.
“We just have a great neighborhood. That’s just crazy; it’s absolutely crazy,” Helen Hoagland told the newspaper.
She said the children used to decorate the entrance to the neighborhood each Christmas, but stopped a few years ago.
Police told the Tulsa World that they have not been called to the home in the past for domestic violence.
5. The Neighborhood Is Surrounded by a Country Club
The neighborhood where the home is located is surrounded on three sides by the Indian Springs Country Club and was described by the Associated Press as “well-established.”
The home where the victims were found was sold for $245,000 in 2007, the AP reports.
