A University of Alabama graduate opened fire at a bank in downtown Louisville Monday morning, killing at least four people and wounding several others.

The alleged shooter, Connor Sturgeon, was also killed, police in Kentucky said in an afternoon press conference. He was an employee at the bank, police said.

Police Chief Jacquelyn Gwinn-Villaroel said Sturgeon was 23 but other accounts state his age was 25.

Sturgeon attended the University of Alabama from the fall of 2016 through December 2020, according to Shane Dorrill, UA’s assistant director of communications.

Sturgeon completed his undergraduate studies with a double major in finance and economics. He then received a Master’s of Science Degree, also from the University of Alabama.

According to Sturgeon’s LinkedIn profile, he was a syndications associate and portfolio banker with Old National Bank in Louisville following completion of the ONB Commercial Banking Development Training Program in April 2022.

His profile also said he was on the Young Professionals board for Junior Achievement of Kenuckiana.

Sturgeon’s family lived in Greenville, Indiana and he graduated from Floyd Central High School, where he played basketball where his father, Todd Sturgeon, was head basketball coach, the Louisville Courier Journal reported.

The gun used was an AR-15-style rifle, CNN reported. Sturgeon may have had mental health issues, NBC News reported.

Louisville Metro Police Department Deputy Chief Paul Humphrey told reporters officers who arrived on the scene that officers “encountered active gunshots still being fired inside the location at that time.”

An Instagram account that apparently belonged to Sturgeon was taken offline after the shooting, shared memes, WDRB TV reported.

That account, that report stated, posted two movie quotes: “I know what I have to do but I don’t know if I have the strength to do it,” and “I could burn the whole place down” — the latter he described as “Monday vibes.” His account also posted the words, “They won’t listen to words or protests. Lets see if they hear this”.

Officers exchanged gunfire with the shooter, who appeared to be a former employee of the bank. It was not clear if he was shot to death by police or shot himself.

Nine people, including two police officers, were treated for injuries from the shooting, University of Louisville Hospital spokeswoman Heather Fountaine said in an email.

One of the officers was in critical condition, she said. At least three patients had been discharged.

“Please pray for all of the families impacted and for the city of Louisville,” Kentucky Gov. Andy Beshear tweeted.

The shooting happened in a building on East Main Street not far from the Louisville Slugger Field and Waterfront Park.
