In the early morning of March 8, 2020, a night at the Cheetah Club in Milwaukee ended with the fatal shooting of 31-year-old Derick Murry. Surveillance footage shows a man, later identified as the brother of Joseph C. Hallio, stumble into Murry and kiss him on the face, prompting a verbal dispute that became physical. Murry pushed and punched that man. From a distance Hallio intervened and shot Murry multiple times at point-blank range, killing him. A patron who tried to break up the fight was also shot and hospitalized with serious injuries.

Hallio then engaged in a gunfight with the club’s security guard; both men were wounded. Hallio’s sister, Stephanie Sykes, drove him to a hospital and declined to cooperate with police. Based on the investigation, Hallio was arrested and charged with multiple felonies including first-degree reckless homicide and was held on $150,000 cash bail; Sykes was charged with aiding a felon.
