The FBI is searching the woods off the Highway 153 exit of Amnicola Highway.
The Tennessee Highway Patrol and Chattanooga Police are on scene controlling traffic. Authorities have parts of the woods taped off with yellow caution tape.
This area is a new focus for the FBI, and has not previously been a part of the investigation into two attacks on military installations in Chattanooga by a 24-year-old gunman who fatally shot four servicemembers before falling in a hail of police gunfire.
Agents brought a K-9 unit to the exit ramp used by the gunman in his journey from his first target on Lee Highway to his second target on Amnicola Highway.
FBI agent Jason Pack said the agency is following up on a lead in the ongoing investigation, but did not offer any specifics.
