NACOGDOCHES, Texas (KTRE) -Authorities were called around 11 p.m. last night to a log building on fire in Hemphill. This building is located on Sabine Street in Hemphill. The building was unoccupied but had recently changed ownership to MT Nails who owns the building next door. “It came in actually reported as a grass fire, and once our first truck arrived on scene, they discovered it was a fully involved structure fire. We do believe it started on the front porch section of the building,” Hemphill assistant fire chief, Jon Daffron said.
