The Lindale fire came after two weekend church fires in Tyler, about 100 miles east of Dallas. Authorities have not said the fires are linked, or whether arson was the cause.
Agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives moved in last week after three church fires were reported over 12 days in nearby Athens.
The Athens blazes caused officials to re-examine a church fire in Canton, 40 miles west of Tyler.
