Investigators are trying to determine if a firefighter charged with two arsons in a fire-plagued eastern Pennsylvania town could be responsible for other blazes.

Robert Tracey Jr., 37, was charged Monday with lighting two small trash fires in Coatesville last week. Authorities said he was a firefighter in the town of 11,000, which has had nearly two dozen arsons so far this year.

Investigators with the Bureau of Alcohol, Tobacco, Firearms and Explosives say they are still searching for a possible motive. Special agent Tom Stankiewicz said the agency is looking for any possible links between Tracy and other unsolved fires.

A message left for an attorney who has represented Tracey was not immediately returned Tuesday.

Police have made about a half dozen arrests in connection with the fires.
