Update 12:00 p.m. — According to a police report released to New Times, MBPD were called by a parking attendant near Lennox Avenue and Fifth Street who witnessed Quarless' dispute and the gunshots.

According to the parking attendant, Quarless and another man — identified as Michael Ritchie, a 31-year-old from New York — were leaving the garage in a black Porsche Panamera when they approached a white car filled with several women. An argument ensued, with the attendant hearing the women yell "No, get away, leave me alone!"

That's when Quarless took out a semi-automatic handgun — ID'd by police as a .45 caliber weapon — and fired two shots, one straight up into the sky. Why? When police later interviewed a woman in Quarless' car, she said he'd fired "in an attempt to emphasize his dominance and manhood."

Police quickly responded when the parking attendant called 911, and found the black Porsche a few blocks away. Quarless was soon found trying to hide in front of Siena Tavern, police say, "attempting to conceal himself and a black firearm in a nearby plant."

Police dug the gun out of the plant and later matched rounds found on the ground near the garage with the gun. Quarless was arrested on a misdemeanor account of firing a firearm in public and taken to Turner Knight Guilford Correctional Center for processing.
