Suspect bought AR-15 legally last week
The suspected shooter, 25-year-old Connor Sturgeon, bought the AR-15 legally on April 4 in Louisville, Jackie Gwinn-Villaroel, interim chief of the Louisville Metro Police Department, said at a news conference Tuesday.
Sturgeon was a current employee of the bank where the "targeted" shooting unfolded, she said.
Police said body camera footage from officers who responded to the shooting will be released Tuesday afternoon.
A vigil will be held Wednesday at 5 p.m. at the Muhammad Ali Center, Louisville Mayor Craig Greenberg said.
The mayor noted that, under Kentucky law, the gun used in Monday's mass shooting will one day be auctioned off and back on the street.
He pleaded, "It's time to change this law and let us destroy illegal guns and destroy the guns that have been used to kill our friends and kill our neighbors."
"Five more families have lost a loved one," the mayor said.
"This is happening in America everywhere and will keep happening until we say 'enough' and take meaningful action," he said. "Doing nothing is not a strategy, is not a solution."
The suspect left a note and "texted or called at least one person to let them know he was suicidal and contemplating harm," Rep. Morgan McGarvey, D-Ky., said at Tuesday's news conference.
"But we don't have the tools on the books to deal with someone who is an imminent danger to themselves or to others," he said.
"We can come together at the federal level, working with each other to solve this problem which is impacting all of us in a uniquely American way, and get universal background checks so people who shouldn’t have a gun can't buy one," McGarvey said.
"That is not a political issue, but it becomes one when Kentucky Republicans would rather ban books and pronouns, and then make Kentucky a sanctuary state for weapons," he said.
