OKLAHOMA CITY (KFOR) – Authorities are releasing more information about a deadly shooting in a popular Oklahoma City area.

“Heard a bang and thought it was part of the movie. Next thing you know, the movie ended, and we came outside and seen all the tape,” said movie-goer Bertoldo Berruete. 

It’s a popular spot in Bricktown, but Monday night it was filled with gunfire and crime-scene tape. 

“It’s actually scary. It was just an ordinary day. And that happens?” said another movie-goer, Mary Jane Gonzalez. 

Shortly before 10 p.m. on Monday, Oklahoma City police were called to Harkins Theatre in reference to a shooting.

Investigators say a couple was walking when they were approached by a man armed with a gun. 

“The man who was armed pointed the gun at the male and demanded his belongings,” said Msgt. Gary Knight. 

The suspect robber, identified by police as Travis Prince.

The man he’s accused of holding up, Christopher Cooper, pulled out his own gun and opened fire, killing Prince. 

“It appears that the deceased simply walked up to them, decided that is who he was going to rob pointed a gun at them and that is when he was shot and killed,” said Msgt. Knight. “Every citizen has the right to defend their life.”

Police say Cooper stayed at the scene and spoke with detectives. 

“They were interviewed by homicide detectives shortly after the case because even though this appears on the surface to be a case of self-defense it’s still a homicide,” said Knight. “In a case like this, when somebody approaches you with a gun and a person perceives that their life is in imminent peril the law gives you that right”, he said. 

This entire incident left movie-goers on edge. 

“You can never just come out and think everything’s ok It’s just an ordinary day you know? You should have something to defend yourself at least. You never know what may happen in your ordinary life,” said Berruete. 

Although it appears to be a case of self-defense police say this is still an active homicide investigation. 

It will now be up to the District Attorney to decide if the shooting was justified.
