LOUISVILLE, Ky. — Quintez Brown, the 21-year-old Black activist charged with attempted murder after allegedly firing a gun at Louisville mayoral candidate Craig Greenberg (D) and his staff, is out on bond after a community fund posted his $100,000 bail.

Brown is now on home incarceration. Chanelle Helm, an organizer with Black Lives Matter Louisville, presented the cashier's check with the bail payment on behalf of the Louisville Community Bail Fund.

Louisville inmates released to home incarceration are fitted with a GPS ankle monitor, said Steve Durham, a spokesperson for Louisville Metro Corrections.

A judge on Tuesday ordered Brown to have no contact with Greenberg or his campaign staff and said he cannot possess firearms. Brown’s lawyer said the man has “serious mental issues” and said he would undergo a psychiatric evaluation.

Greenberg said he was at his campaign headquarters with four colleagues when a man appeared in the doorway and began firing multiple rounds. One staffer managed to shut the door, which they barricaded using tables and desks, and the suspect fled.

Police apprehended him a short time later, less than a half-mile from the scene. A police report said Brown was carrying a loaded 9 mm magazine in his pants pocket and had a drawstring bag with a handgun and additional handgun magazines.

Brown is also charged with four counts of wanton endangerment for allegedly firing shots near Greenberg’s staff.

Police said Brown appears to have acted alone and the motive remains under investigation.

The Louisville bail fund said on its social media page that it “exists to not only bail out folks, but provide post-release support to get them from jail, fed, and to a situation of safety.”

Brown disappeared for about two weeks last summer. After he was found safe, his parents issued a statement asking for patience and privacy while they attended to his “physical, mental and spiritual needs.”

Brown, a social justice activist running as an independent for the council, has campaigned with a slate of candidates opposed to projects that they say will worsen gentrification in Kentucky’s largest city.

The apparent target of Monday’s shooting, Greenberg has touted his experience at the center of the city’s revitalization efforts, and helped draft legislation promoting developments in Louisville’s predominantly Black west side.

Greenberg said in an interview with The Associated Press on Tuesday that his ears were still ringing from the gunshots fired at him the day before. Despite the attack, he said his resolve to run for mayor has not wavered.

“If there’s any good to come out of this, I hope it’s that not only will I be a more effective mayor, but that I’ll be someone who can bring the city together to unify around implementing solutions to end gun violence,” he said in a phone interview.

He said his team has tightened security but that he is committed to continuing to campaign in public.

“I’m focused on bringing people together,” Greenberg said. “It’s unfortunate that too many things right now are dividing people and I would hope that people start lowering the temperature.”
