JEFFERSONTOWN, Ky. -- A white man with a history of violence and mental illness was recorded on surveillance video apparently trying to get inside a predominantly black church in Kentucky before he went to a grocery store and
After releasing a photo of the suspect, authorities received a tip from an employee of the city of Jeffersontown who said he thought he saw Gregory Bush outside the First Baptist church prior to Wednesday's shooting, city police chief Sam Rogers said. The video confirmed Bush's presence, Rogers said. The church is headed by a black pastor and has a large African-American membership.
Bush "appeared to try to gain access to the church," Rogers said.
The information came as news media outlets reported that Bush made a racial comment after the deadly shooting at a Kroger in Jeffersontown, a city of about 26,600 people on the outskirts of Louisville.
Rogers said it was too soon, however, to say whether the shooting was racially motivated.
"I can't speculate on motive at this time," the chief said at a news conference Thursday. "We are pursuing all avenues of the investigation no matter where that takes us or what it involves."
The FBI announced it "is evaluating the evidence to determine if there were any violations of federal law." Hate crimes are prosecuted under federal law.
More than 100 people gathered outside Kroger store Thursday night to pay tribute to the victims, reports CBS Louisville affiliate WLKY-TV.
Friends and family members of the victims told the station they found comfort in the gathering.
"This helped to renew my faith in human kindness -- this movement, this beautiful thing," said Kevin Gunn, the nephew of one of them.
Chief Rogers said Bush apparently does have a history of mental illness, as news outlets have reported.
An arrest report says Bush walked into the Kroger, 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. Each victim died of multiple gunshot wounds, Rogers said.
A man carrying a concealed weapon who happened to be in the parking lot challenged Bush, and police say the suspect then "began firing wildly" at him, putting other shoppers in the parking lot in danger. Neither man was hurt in that confrontation, Rogers said.
Bystander video shows a white man in a distinctive neon-yellow shirt trying to drive away while an officer chases after him on foot. Many more officers converged on the scene and made the arrest just a few hundred yards from the store Wednesday afternoon.
Bush was jailed on $5 million bond Thursday on two counts of murder and 10 counts of felony wanton endangerment.
Ed Harrell was quoted by the Courier Journal of Louisville as saying 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. Harrell 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."
Rogers said police "are aware of that statement and are evaluating any factors that may come into play with" it.
He said he had "no direct knowledge" of whether there was more than one armed bystander at the scene.
The local coroner's office identified the victims as Maurice Stallard, 69, and Vicki Lee Jones, 67. Police said there didn't appear to be any connection between Bush and the victims, or any link between Bush and the Kroger store.
Stallard's 12-year-old grandson was shopping with him in the store when he was gunned down, Jeffersontown Mayor Bill Dieruf said Thursday. The boy was physically unharmed, but most certainly traumatized, the mayor said, adding, "He was there and cannot unsee what he has seen."
Stallard was 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."
"People getting shot at a grocery store, a school, outside a church. Can't we all agree that that is unacceptable?" said Fischer, a Democrat running for re-election.
Authorities removed computers and cellphones from the house where Bush lived with his parents.
Bush's criminal record shows he threatened his ex-wife and punched a deputy sheriff during a family court hearing years ago. He also was charged with assaulting his elderly parents in January 2009.
An arrest citation said Bush's parents were punched and choked, and they told police they were "terrified of (his) unpredictable behavior."
