BROKEN ARROW, Oklahoma - Broken Arrow Police said they found two bodies after forcing their way into a home after a gunshot was reported by a neighbor. Police said Thursday afternoon that it appears the shooting was a murder-suicide.

Police said the bodies are those of a man and woman believed to be in their 60s. The situation began as a domestic violence incident, according to police but they have not confirmed whether or not it was a murder-suicide.

Broken Arrow Police said a neighbor called at about 6:30 a.m. to report a loud pop at a home in the 4400 block of West Fort Worth. Police believe that pop was a gunshot.

Officers were unable to make contact with anyone inside and out of caution they put Anderson Elementary School on lockdown and called out their special operations team. 

Eventually, officers made the decision to go inside, where they found the two bodies. Inside the home, officers found an unresponsive woman inside a bedroom and saw that she had died from gunshot wounds. Police said in the same bedroom they found a man who'd also died of gunshot wounds. 

Police say a small pistol was found close to the bodies.

"We don't have any confirmed ages. The information I had suggests they're in their sixties," said BAPD Officer James Koch. "Dealing with these types of situations, we always prepare for the worst," he said.

Nearby Andersen Elementary School went on lockdown as a precaution, but that's since been lifted.

Police said the medical examiner will determine the cause of death of the man and woman. 

The man and woman's names aren't yet being released pending family notification.
