Louisville bank employee livestreamed attack that killed 5

A Louisville bank employee armed with a rifle opened fire at his workplace Monday morning, killing five people — including a close friend of Kentucky's governor — while livestreaming the attack on Instagram, authorities said.

Police arrived as shots were still being fired inside Old National Bank and killed the shooter in an exchange of gunfire, Louisville Metro Police Department Chief Jacquelyn Gwinn-Villaroel said. The city's mayor, Craig Greenberg, called the attack "an evil act of targeted violence."

The shooting, the 15th mass killing in the country this year, comes just two weeks after a former student killed three children and three adults at a Christian elementary school in Nashville, Tennessee, about 160 miles (260 kilometers) to the south. That state's governor and his wife also had friends killed in that shooting.

In Louisville, the chief identified the shooter as 25-year-old Connor Sturgeon, who she said was livestreaming during the attack.

"That's tragic to know that that incident was out there and captured," she said.

Meta, the company that owns Facebook and Instagram, said in a statement that it had "quickly removed the livestream of this tragic incident this morning."

Social media companies have imposed tougher rules over the past few years to prohibit violent and extremist content. They have set up systems to remove posts and streams that violate those restrictions, but shocking material like the Louisville shooting continues to slip through the cracks, prompting lawmakers and other critics to lash out at the technology industry for slipshod safeguards and moderation policies.
