Investigators have released sketches of three persons of interest in a string of Texas church fires.

Images of the three men were provided Friday at a Tyler news conference by Special Agent Robert Champion with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Two church fires Monday northwest of Tyler have been ruled arson. The fires damaged Dover Baptist Church and Clear Spring Missionary Baptist Church.

Those fires brought to nine the number of deliberately set east Texas church fires since Jan. 1. ATF says another church fire in Temple, about 120 miles south of Dallas, also was arson.

No injuries have been reported.

The images released Friday show one man with short hair and a flame-like tattoo on his neck, another short-haired man with a cross on his left forearm, and a third man with longer hair.
