Tuscaloosa Shooter Used Military Style Assault Rifle A man armed with a military style assault weapon fired through the window of a crowded bar early today and then shot at patrons as they rushed outside to escape the gunfire. Police said 17 people were injured, but remarkably, no one was killed. We believe that it was not a random act. There were people on the sidewalk where he stood for several minutes before firing," Tuscaloosa Police Chief Steve Anderson said at a news conference today. "We believe from what we've seen in the video that there was a target inside the bar," the police chief said. At least four the injured were students, police said. One on the wounded individuals is in very critical condition, while three are in critical condition, Anderson said. We don't have the number of shots fired. We think at least 11. We don't know how many were hit by shrapnel or bullets that ricocheted," Anderson said. The suspect is described as a white male between 5-foot-7 and 5-foot-9 with a stocky build. He was using a military-style assault weapon, police said. Anderson said the gunman walked up a hill on 23rd Street to the bar, fired through the bar window and then shot at people as they fled the bar. After the shooting, the suspect walked back down the hill. "As far as we know he fled in the same direction that he came from," Anderson said. He walked up to the bar on foot as well. Police are now working with federal officials to have the video of the gunman enhanced. Authorities are investigating whether the shooting at the Copper Top Bar is related to a separate shooting at the Indian Lakes Subdivision in Northport, Ala., about 45 minutes earlier. "Right now we are exploring that possibility," Anderson said. We have not made a solid connection to that shooting. That incident, which occurred at 11:47 p.m. involved two people who were attacked by a shooter in their home. One person was wounded in that shooting. Those inside the bar at the time of the incident told ABC 33/40 that it sounded like fireworks were going off, while a man who was shot said he quickly realized it was someone on the outside firing into the bar. Four have been admitted to the hospital. After the shooting police canvassed the area on foot, and had a helicopter aloft to see if there was anyone wounded who had been missed, while investigators were collecting shell casings forensic analysis, Anderson said.
