LENOIR CITY, Tenn. (WVLT) -- A suspect search is underway after one person was shot in the head with what looks to be an AR-15 in Lenoir City, police say.

Authorities were called to check on reports of a shooting at Riverview Manor Apartments on Industrial Park Drive in Lenoir City at 12:56 p.m. Police left the scene just after 3 p.m.

Dispatchers said one person had been shot. A victim identity was not immediately released, but officers said the victim was alert when they arrived and taken to UT Medical Center for treatment.

Police identified Michael Smith of Knoxville as the shooting suspect. Smith is believed to be in a late model Ford F-150 maroon four-door truck with a toolbox in the back with possibly a white or silver stripe down the truck. Investigators believe Smith is in Loudon or Knox counties, but said he could have gone anywhere.

A witness on the scene told WVLT News she threw her kids in the car and drove away from the apartment complex after seeing a man get shot several times while sitting in a car.

"I heard some arguing, next thing I know I saw a gun come out the window. I threw my kids in the car and heard one pop. I turned around and just started calling 911," witness Ashley Richardson told WVLT News.

Richardson also reported seeing the suspect speed away from the apartment complex.

Sheriff: 'Armed and dangerous' Knoxville man on the run after shooting in Lenoir City

knoxnews.com-A Knoxville man is on the run after authorities say he shot another man in the head at an apartment complex in Lenoir City on Tuesday afternoon.

Loudon County Sheriff Tim Guider identified the suspect as Michael Smith, age unavailable. Smith may be driving a maroon, four-door Ford F150 pickup truck, and he should be considered armed and dangerous, Guider said.

Smith and the victim had parked their vehicles side by side at River Manor Apartments when the shooting erupted about 1 p.m., Guider said.

Guider said Smith brandished an "AR pistol" and shot the victim at least twice — in the head and the arm — as each man sat in the driver's seat of his vehicle. Deputies found nine spent bullet rounds in the parking lot, Guider said.

The victim, whose identity has not been released, was flown via LifeStar helicopter to the University of Tennessee Medical Center. His condition wasn't immediately available Tuesday evening.

A female passenger and a 2-year-old child were in the victim's vehicle at the time of the shooting, Guider said. They were unharmed.

Investigators believe Smith and the victim had been "feuding for some time," Guider said, but it's unclear what they were feuding about.

Guider said authorities are still working to get an accurate photo of Smith.
