Louisville: A shooting at Old National Bank left 8 injured and 5 dead. The attacker, an employee of the bank itself, was shot and killed by police following a shoot-out after the initial shooting occurred.

The attacker live-streamed the attack which took place about 30 minutes before the bank was to open.

“Our city is heartbroken,” Louisville Mayor Craig Greenberg told CNN’s Wolf Blitzer on Tuesday evening. “These five victims should not be dead – just like everyone else who was killed by gun violence in our city, in our country, should not be dead.”

The gunman used an AR-15-style rifle which police say he’d legally bought six days before the attack. This is a common gun choice among many US mass shooters.

Kentucky is quite relaxed when it comes to gun laws. The state has no “Red flag” laws, no universal background checks, and no waiting period between buying a firearm and taking possession of it. The state also has permit-less concealed carry. According to the CDC, those relaxed gun laws help explain why the state has a firearm death rate higher than the national average.

The city held a vigil at 5 p.m. Wednesday to “acknowledge the wounds, physical and emotional, that gun violence leaves behind”, the Louisville mayor told reporters Tuesday. “It will be an interfaith opportunity for our entire community to come together – to grieve, to heal, to begin to move forward.”
