Tennessee ? A customer opened fire in a crowded shopping mall Wednesday afternoon in Knoxville, killing a clothing store employee before he was shot and wounded by police officers, authorities said.

The employee was shot multiple times around 4:20 p.m. after a confrontation with the suspect at Knoxville Center Mall, police spokesman Darrell DeBusk said. The store employee, 29-year-old Ahmed Nahl, died at the scene.

Two uniformed Knoxville Police Department officers confronted the customer as he left Reno Menswear store and exchanged gunfire, hitting him once in the arm and once in the leg, DeBusk said. No one else was hurt, and police recovered the suspect’s handgun.

William Johnson, 42, of Knoxville, was charged with murder, aggravated kidnapping and two counts of attempted murder in the shootings, police said. He was taken to University of Tennessee Medical Center and was in stable condition.
