LOUISVILLE, Ky. – A frantic call from an Old National Bank employee and a much calmer one from a co-worker hiding in a closet provided Louisville police the first indications of the carnage caused by a gunman’s attack, according to audio of 911 calls released Wednesday.

The shooter’s mother tried to prevent the mayhem, reaching out to police and saying her son “currently has a gun and is heading toward” the bank, but it was too late. 

Together, the 911 calls and the body camera video released Tuesday fill out details of the chaotic scene surrounding Monday’s assault and the police officers’ heroic response.

Five people were killed and eight injured by a bank worker identified as Connor Sturgeon, who police said was armed with an AR-15 rifle. Authorities said officers arrived at the scene three minutes after being dispatched, likely saving lives.

“Oh my God, there’s an active shooter there,” says a panicked woman identified as the first 911 caller. “I just watched it on a Teams meeting. … We were having a board meeting with our commercial (lending) team.”

An initial picture of the harrowing Monday morning scene develops as the operator asks the woman for the bank’s address, where specifically the shooting was taking place and what the assailant looked like.

As more calls start to come in, the operator excuses himself and tells her, “We have them (police officers) going that way. … We do have everybody responding. We’re getting them out there.’’

One of the callers says she’s calling from inside a closet in the building as numerous gunshots are heard in the background. She gives a description of the shooting and says she knows the perpetrator: “He works with us.”
