A white man with a history of violence fatally shot two African American customers at a grocery store and was swiftly arrested as he tried to flee, authorities said Thursday.
The suspect made a racial comment to a man he encountered on his way out, the Courier-Journal of Louisville reported.
An arrest report says Gregory Alan Bush walked into a Kroger market outside Louisville, pulled a gun from his waist and shot a man in the back of the head, then kept shooting him multiple times "as he was down on the floor." The report says Bush then reholstered his gun, walked outside and killed a woman in the parking lot.
A video shot by a bystander shows a white man in a neon yellow shirt trying to drive away while an officer runs after him. More officers converged on the scene and made the arrest Wednesday afternoon.
Bush, 51, was jailed in lieu of $5-million bond Thursday on two counts of murder and 10 counts of felony wanton endangerment.
The FBI announced that it "is evaluating the evidence to determine if there were any violations of federal law."
Jeffersontown Police Chief Sam Rogers said in an initial news conference at the scene that "we have no idea" what motivated the shootings.
Ed Harrell told the Courier-Journal that he was waiting for his wife in the parking lot when he heard gunshots and grabbed his revolver. As he crouched down, he said he saw the gunman walk "nonchalantly" by with a gun by his side. He said he called out to ask what was going on, and the gunman replied: "Don't shoot me. I won't shoot you. Whites don't shoot whites."
The local coroner's office identified the victims as Maurice Stallard, 69, and Vicki Lee Jones, 67. Stallard is the father of Kellie Watson, the chief racial equity officer for Louisville Mayor Greg Fischer.
The mayor shared his outrage Thursday over what he called an "epidemic of gun violence" that "hit close to home."
"Somehow, a few have become so beholden to politics that they place a higher value on that than on the lives of our fellow Americans," said Fischer, a Democrat running for reelection.
"People getting shot at a grocery store, a school, outside a church. Can't we all agree that that is unacceptable?" Fischer said at a news conference.
Bush's criminal record shows he threatened his ex-wife and punched a deputy sheriff during a family court hearing years ago.
An arrest record from May 2009 says Bush became "irate" and shouted obscenities and threats at his ex-wife. When deputies tried to subdue him, he fought off attempts to handcuff him and he punched a deputy twice. He was charged with several counts, including assault, resisting arrest and disorderly conduct. Bush also was marked as a "suicide risk" on the arrest sheet, which noted that his ex-wife had a protective order against him.
In a 2003 incident, Bush was charged with menacing for following a 15-year-old into a movie theater bathroom and putting his hands around her waist. Bush told the girl he "thought we were family" and the girl pushed him away, according to the arrest record.
Bush's attack on customers caused chaos at the Kroger.
Eric Deacon, who identified himself as an emergency medical technician, said he was in the store's self-checkout lane when he heard the first shot, in the pharmacy area.
He said a man came around the corner and "the look on his face, he looked like he just didn't care."
Then Deacon went outside and saw a woman who had been shot and tried to resuscitate her.
"She was gone; there's nothing I could do," Deacon said. "I think she just got caught in the crossfire."
