A Louisville civil rights activist was arrested Monday in connection with an assassination attempt against a mayoral candidate. But if the accusations against him are true, it is unclear why a young man so civically engaged might have allegedly become involved in such a plot.

Police say Quintez Brown, 21, —who announced in December that he would be running for a seat on Louisville's metro district council— entered the campaign offices of Craig Greenberg and allegedly shot a 9mm Glock semi-automatic weapon at him, grazing his shirt, according to the Louisville Courier-Journal. A motive has not yet been determined.

"My team is blessed no one was physically injured today," Greenberg said at a press conference. However, police evacuated Greenberg and his staff from the building, the Courier-Journal reports.

Ten minutes later, police found a man who matched the suspect's description about a half-mile from the campaign office building. Video from a surveillance camera caught the suspect in clothing matching Brown's when he was found. He allegedly had a loaded 9mm magazine in his pocket and additional magazines in his bag.

At his first court appearance on Tuesday morning, Brown was charged with attempted murder and four counts of wanton endangerment, according to records. He has pleaded not guilty to the charges. His bond was raised from $75,000 to $100,000, local station WLKY reports.

His lawyer, Rob Eggert, said during the arraignment that he believes there are "serious mental issues at play here" and plans to have Brown evaluated. His next court date is Feb. 23.

Brown was a senior at the University of Louisville and was involved in the 2020 racial justice protests in Louisville centering around the police shooting death of Breonna Taylor. He was a well-known community leader, working with Black Lives Matter Louisville and the University of Louisville's Youth Violence Prevention Research Center.

He had also interned at the Courier-Journal and was a founder of From Fields To Arena. The newspaper describes it as a group that provides political education and violence prevention training to young people in hip-hop and sports.

But last summer, Brown disappeared on June 19 and was reported as missing, and he was found safe in New York on July 1. In a statement released through Black Lives Matter Louisville, his family asked for time while dealing with Brown's situation.

"We are asking for privacy and would appreciate everyone's patience and support while we tend to the most immediate need, which is Quintez's physical, mental, and spiritual health," according to the statement.

"Through this experience, it has been evident that the institutions in Louisville are ill-equipped to support families and people in these situations. We encourage everyone to check in on those near to their hearts."

In December, Brown announced that he would be running for Louisville’s metro district council through social media. Later, in a Jan. 10 Medium.com article, Brown wrote what he called a “Revolutionary Love Letter,” stating: “We have been educated to use our minds narrowly and forced to identify ourselves with roles that trap us in a collective perpetual state of anxiety. We have forgotten how harmonious this thing called life is and have fallen victim to a vicious circle of pain and suffering.”
