The Knoxville Fire Department responded to a report of a structure fire at 410 South Kent in Knoxville Sunday evening shortly before 7:00 p.m. Crews arrived to find the resident had been burning leaves in his fire pit that was close to a shed, and with the wind and dry conditions the fire was able to spread to the exterior of the shed.  Crews were able to extinguish the fire in the shed and leaf pile before it spread to any other structure.
