A 21-year-old man in Tennessee opened fire apparently at "random" outside an outlet mall near Great Smoky Mountains National Park, killing a woman and wounding a man before turning the gun on himself, police said.

The gunman was identified as Leon Steven Jones of Newport-Sevierville, Tennessee.

The woman was 24-year-old Olivia Katel Cunningham of York, Pennsylvania.

The wounded man, 75-year-old John Marr of Templeton, Massachusetts, was rushed to University of Tennessee Medical Center. His condition wasn’t known.

Investigators said it appeared the shooter didn’t know either victim, adding that none of them were related. All three were shot with a semiautomatic handgun, Sevierville police spokesman Bob Stahlke said.

"I don’t know if he was going to shoot one and two people and then do what he did, or if his intent was to shoot more. I just don’t know. But all we can do in law enforcement is to get here as quick as we can. And this situation was over when we got here," Stahlke said, as the Knoxville News Sentinel reported.

The police spokesman said there no longer was any threat, and the Tanger Outlets mall remained open except for a small area cordoned off as a crime scene.
