Shooter was notified he’d be fired from Old National Bank and wrote a note to his parents and friend, source says. Five people were killed.

Louisville officials will hold an 11:30 a.m. ET briefing today on the fatal workplace shooting, according to a news release.

The release says officials will “provide updates on the aftermath of Monday’s shooting and announce a planned vigil.”

Here’s who we expect to speak at the briefing:

Investigators combing through Instagram video of the shooting saw firsthand the horror that unfolded Monday, watching the shooter fire his AR-15-style weapon inside the bank for about a minute and then appearing to wait a minute and a half before police arrive, according to a city official.

It’s unclear why the gunman stopped shooting. 

The video shows that his attack on bank workers lasted about a minute, the official told CNN.

The live stream begins with the clearly visible AR-15-style weapon before a worker inside the bank says good morning to the gunman, according to the official.

“You need to get out of here,” the shooter is heard saying to the woman on the live stream, which was eventually taken down by Instagram’s parent company Meta. 

According to that official, the gunman then tries to shoot her in the back but can’t because the safety is on and the weapon still needed to be loaded, the official said. Once the shooter loads the weapon properly and takes the safety off, he shoots the worker in the back, the official said. Her condition is not known. 

The shooter then continues his rampage, firing at workers while they try to outrun the gunman, the official said.

The shooter does not go to other floors of the bank where workers were already present, the official said. 

Once the shooter was done firing, he sat down in the lobby area that looks out onto East Main Street and appears to wait for police, the official said.

The gunman waited roughly a minute and a half before police arrived and engaged the shooter in the gun battle, according to the official. 

Authorities “will make every effort” to release body camera and surveillance footage of the bank shooting “as soon as possible,” Louisville Metro Police spokesperson Aaron Ellis said.

“We are still in the infancy of this investigation,” he added.

A spokesperson for the Louisville mayor also told CNN the office hopes to release the 911 call audio of Monday’s shooting at Old National Bank later Tuesday.

The mayor has seen the surveillance footage, the spokesperson said. 

“It’s clear the initial responding officers immediately engaged the shooter,” the spokesperson said, adding the officers undoubtedly saved lives and noting there were other people in the building.

Separately, a Louisville Metro Police dispatcher said in an audio that the gunman, identified as Connor Sturgeon, had left a voicemail saying he was going to kill everyone at the bank.

“He’s texted a friend, called a friend, left a voicemail saying he’s gonna kill everyone at the bank. Feeling suicidal,” the dispatcher said in the audio.

Old National Bank CEO Jim Ryan and other members of the bank’s leadership team are in Louisville Tuesday to provide support to individuals affected by Monday’s mass shooting, according to a statement from the bank, which adds that they will continue to be there in the days ahead.

“Obviously, this is an incredibly difficult situation, and our entire focus is on making sure that everyone affected has the support and assistance they need,” the CEO’s statement reads. “On behalf of everyone at Old National, I also want to acknowledge and thank Louisville law enforcement, the medical community and state and local officials for their incredible response to this tragedy. And finally, we ask you to please continue to pray for all those affected.”

The shooting at Old National Bank in Louisville, Kentucky, began around 8:30 a.m. ET, police said, about 30 minutes before the bank opens to the public.

Bank staff were holding their morning meeting in a conference room when the shooter opened fire, Rebecca Buchheit-Sims, the bank manager, said.

One bank employee frantically called her husband as she sheltered inside a locked vault, the husband, Caleb Goodlett told CNN affiiliate WLKY. By the time he called 911, police were already aware of the shooting, he said.

“Just a very traumatic phone call to get,” Goodlett told the affiliate, adding that he has since seen his wife and she is OK.

The gunman, who was still firing when police arrived, was killed in a shootout with officers, police officials said.

Nickolas Wilt, a 26-year-old rookie officer, ran toward the gunfire and was shot in the head, interim Louisville Metro Police Chief Jacquelyn Gwinn-Villaroel said. He had graduated from the police academy just 10 days before the shooting. Wilt underwent brain surgery and was in critical but stable condition as of Monday afternoon, the chief said.

The gun used in the shooting was an AR-15-style rifle, a federal law enforcement source told CNN. The semi-automatic rifle is the most popular sporting rifle in the US, and 30% of gun owners reported having owned an AR-15 or similar-style rifle, according to the 2021 National Firearms Survey. The AR-15 and its offshoots have been the weapon of choice in many of the most horrific mass shootings in recent memory, including the Covenant school shooting in Nashville just two weeks ago.

The bank sits on the fringe of Louisville’s developing downtown business district, state Sen. Gerald Neal, who represents the district where the shooting happened, told CNN. 

CNN’s John Miller, Laura Ly, Artemis Moshtaghian, Celina Tebor, Caroll Alvarado, Kristina Sgueglia, Sara Smart and Eric Levenson contributed to this report.

Louisville Mayor Craig Greenberg praised his community after a bank shooting Monday that left five people dead.

In a CNN interview alongside Louisville Metro Police Department Interim Chief Jacquelyn Gwinn-Villaroel, Greenberg — who said he himself is a survivor of gun violence in the workplace — encouraged those impacted by the shooting to “take time with loved ones.”

The mayor said his friend Tommy Elliott, who was killed in the shooting, was a “great friend” and “the definition of loyalty.” Elliott was also a friend to Kentucky Gov. Andy Beshear and others around the city, he said. 

He recounted having not known whether another friend had survived yesterday’s attack. The mayor said when he saw his friend in the hospital, he was overwhelmed.

“We both survived,” the mayor said he told his friend, encouraging him to see a therapist and talk to professionals.

While the mayor said he doesn’t personally know the others who died, from the stories he has heard, “they are wonderful as well.”

In an interview with CNN, Louisville’s interim police chief offered few further details about the developing investigation into the fatal workplace shooting at a downtown bank in the Kentucky city, revealing that the gunman recently purchased the weapon used in the shooting without providing any more information.

Louisville Metro Interim Police Chief Jacquelyn Gwinn-Villaroel confirmed that police searched the suspect’s home Monday, adding she hopes the items that were recovered will help shed light on the motive.

She did not say whether any other search warrants were executed.

Asked about a note the shooter wrote indicating he was going to carry out a shooting at the bank, the interim chief said the investigation was in preliminary stages.

She said that Officer Nickolas Wilt, who was shot in the head while responding to the shooting, was in critical but stable condition and “looking better.” Wilt graduated from the police academy less than two weeks ago.

She asked for prayers for him and the families of others who lost their lives to “senseless” violence.

Meta, the parent company of Instagram, confirmed that they took down a live-stream video of the Louisville bank shooting.

“We are in touch with law enforcement and quickly removed the live stream,” a Meta spokesperson said. 

Meta declined to comment if the video was taken down on its own or at the request of law enforcement. 

Sources previously told CNN that the shooting was live streamed on Instagram and has been take down but not immediately after the shooting.  

Police are in possession of the video, according to the source.

The mass shooting at the Old National Bank on East Main Street in Louisville, Kentucky, began just after 8:30 a.m. — about 30 minutes before the bank opens to the public, police said.

It happened during a morning employee meeting, with some appearing in person and others virtually, Rebecca Buchheit-Sims, a manager at the bank, told CNN. She watched from her computer as her coworkers were gunned down.

“I witnessed people being murdered. I don’t know how else to say that,” Buchheit-Sims said. 

Buchheit-Sims said she didn’t directly work with the gunman, Connor Sturgeon, but knew him because his father was her son’s high school basketball coach, and her husband was an assistant coach. 

“Just kind of a monotone personality,” she said of Sturgeon. “His temperament is pretty low key. I’ve never seen the kid get angry or upset about anything in public. He was pretty much just relaxed.”
