TYLER, TX - Sketches of three people sought in connection with the spate of church fires in eastern Texas were released Friday along with a plea to the public.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) released the drawings at a news conference in Tyler, Texas, on Friday - one day after two more churches were determined to be victims of arson.

"We have a serial arsonist out there," said Robert Champion, special agent in charge of ATF's Dallas, Texas, office. "We need help from the public."

Over the past two months, a total of 11 churches have been damaged by fire - 10 of which were found to be set ablaze deliberately.

So far, there are no clear links between the fires, which have struck churches of different denominations on different days of the week and at different times of the day.
