A woman who was going to the ATM outside the bank called police after she saw the suspect pacing with a gun.

When officers arrived, they tried to talk him down as customers stayed sequestered inside the bank.

In a statement, police said they tried to de-escalate the situation, using “a variety of active crises intervention and de-escalating techniques.”

During the negotiations, they spoke to the suspect in English and Spanish for several minutes.

After several minutes, authorities said without warning, the man “took a combative stance” and raised his weapon, firing at least once in the direction of the officers.

“The officers returned fire,” said Deputy Chief Gary Kirby. “The suspect was hit and deceased at the scene.”

“Immediately after shots started, he fell to the floor,” he said.

So far, the identity of the suspect has not been released, but authorities said the man has a criminal history and was known to the officers.
