In the autumn of 2020 Mario Walls, 33, was shot in the abdomen in the parking lot of an apartment complex on Beauford Place in Nicholasville, Kentucky. Emergency services responded about 10:47 p.m. on Tuesday, October 13, 2020, and Walls was taken to the University of Kentucky Chandler Hospital, where he died in the early hours of Wednesday, October 14, 2020.

Nicholasville police canvassed the area. Shortly before 1 a.m., an officer at a nearby convenience store encountered 45-year-old Michael Walker, who had a handgun visible at his waist and admitted to shooting Walls. Walker was arrested, initially charged with assault, and after Walls died the charge was upgraded to murder; he was booked into the Jessamine County Detention Center and held without bond. Investigators said they did not believe Walker and Walls knew each other and the motive remained unclear as the investigation continued.

Does anyone have information about Walls, his movements that night, or witnesses who might help clarify what happened?
