UPDATE: The Cumberland County Sheriff's Office has identified the man shot at a rest stop on Interstate 40 near Crab Orchard Tuesday afternoon. 

The shooting happened around 4:30 p.m. Central Time. Deputies were called to the rest area at mile marker 324 eastbound for a report of a man shot in the chest. 

Sheriff Casey Cox said 39-year-old Chadwick Ellsworth Barnthouse, of Virginia, had gunshot wounds to the chest and hand. He was taken to UT Medical Center by helicopter. 

A portion of I-40 was closed temporarily for the helicopter to land. 

While the sheriff's office initially received conflicting witness reports about whether there was a suspect in the shooting, Cox said there was no active shooter at the rest stop, and Barthouse was the only person involved.

He said there is no danger to the public. 

PREVIOUS STORY: The Cumberland County Sheriff's Office is investigating a shooting at a rest stop on Interstate 40 near Crab Orchard that sent one person to the hospital. 

Cumberland County Sheriff Casey Cox told WBIR 10News one person was shot at the mile marker 324 rest area and was taken by helicopter to a Knoxville hospital. The person's condition was not available, but the sheriff said the victim was able to speak to EMS when they arrived. 

The sheriff said they have received conflicting reports from witnesses about whether there is a suspect in the shooting. 

“Right now the investigation is very early on, very vague on suspect information. We’re following up on some tips and leads to see where it takes us in this investigation," Cox said. 

The Tennessee Highway Patrol said a "possible shooter may still be at large."

The sheriff's office has teams out searching for a suspect, but Cox said they are not sure if one exists. Some deputies are stations on Highway 70 as a precaution. 

THP and the Tennessee Bureau of Investigation are assisting in the investigation.

There is a heavy law enforcement presence at the rest area, and a THP helicopter is on the way to the scene. There is no timeline for when the rest area will reopen.
