According to authorities, two individuals were murdered and two others were wounded when gunfire erupted in the parking lot of Hatmaker’s Bar & Grill in Knoxville, Tenn., on Friday night.

At 9:45 p.m Police responded to a report of a shooting outside the Tazwell Park and found 4 male victims with severe gunshot wounds and injuries in the parking lot of the bar.

Following a preliminary investigation, authorities determined that a dispute resulted in the fatal gunshot, which forced witnesses in the parking lot to flee for their safety.

The victims of the shooting, who have not yet been named, were declared dead at the site of the crime. The two wounded guys, who were also not recognized, were brought to the nearby hospital having non-life threatening injuries and were released shortly after.

Because the inquiry is still underway, no suspects have been apprehended.
