A bank manager in Louisville saw her colleagues shot dead while she was on a video call with them

• Five people died after a gunman opened fire at a bank in Louisville, Kentucky, on Monday.
• An employee of the bank told CNN she witnessed the shooting while on a video call with her team.

An employee of a Kentucky bank targeted by a mass shooter said she "witnessed people get murdered" while on a video call with co-workers, CNN reported.

Rebecca Buchheit-Sims, a manager with Old National Bank in Louisville, Kentucky, told CNN that she was on a Microsoft Teams meeting with co-workers on Monday morning when the shooting unfolded.

"Shortly after the meeting started, the gunman, which is an employee, started shooting up the conference room," Buchheit-Sims told the outlet. "I witnessed people being murdered. I don't know how else to say that."

"I'm just as much in shock and disbelief and was in disbelief as I watched it unravel," she added.

Officials said that five people were killed after a bank employee armed with a rifle opened fire at the downtown branch of the Old National Bank.

The gunman, identified by officials as Connor Sturgeon, live-streamed the attack on Instagram, but was later killed by police at the scene, officials added. The video has since been removed from the platform, Instagram's owner Meta said in a statement.

Sturgeon joined the bank as a full-time employee last year after interning there for three consecutive summers between 2018 and 2020, CNN reported, citing law enforcement officials.

Buchheit-Sims told CNN she knew the suspect even though she didn't directly work with him, describing him as having "a monotone personality" and being "extremely intelligent."

"His temperament is pretty low-key. I've never seen the kid get angry or upset about anything in public," she added. "He was pretty much just relaxed."

Sturgeon had recently been told by the bank that he was going to be fired and had written a note to his parents describing his plans for the attack, CNN reported.

There have been almost 150 mass shootings in the US this year, according to The Gun Violence Archive, which tracks incidents in which at least four people are shot or killed, not including the shooter.
