CHICKASHA, Okla. (KFOR) – A homicide investigation is underway in Chickasha after a homeowner shot and killed an intruder Tuesday afternoon.

“It was very scary,” said Nicholle Smith, who lives nearby. “I actually started shaking.”

Officers tell KFOR they were called to the scene near Westbrook St. and W Country Club Rd. around 12:30 Tuesday afternoon.

“Our officers received a call of a domestic disturbance at 3015 Westbrook, in which a subject had broken into the home,” said Lt. Gillian O’Brien with the Chickasha Police Department. “As the subject made entry into the home, the homeowner opened fire right away.”

“I mean, it was pop, pop, pop, pop, pop, pop, pop, pop, pop, pop. I mean, just, you know, as quick as someone could squeeze the trigger,” added Brandon Bowman who lives next door. “I mean, it happened so fast… I walked outside and could smell gunpowder right away.”

The intruder was pronounced dead at the scene. KFOR saw at least a dozen shell casings scattered across the home’s floor.

According to the Chickasha Police Chief, the homeowner did know the man who broke in. However, their exact relationship is not clear.

Why the man broke into the house on Tuesday is also still being investigated by the police department.

“Once we notify next of kin, we may be able to release more details, but it’s going to take some time and investigation,” said Lt. O’Brien.

Officials say whether the homeowner will face charges is up to the district attorney.

More details about the incident are expected to be released later this week.
