Vermont State Police say they are requesting information from the public to help with their investigations of more than a dozen house fires in the Londonderry area dating back to 2005.
Police said many of the fires have been classified as suspicious and investigators have found "striking similarities" in each.
Police say they are working with other state, local and federal agencies to re-examine the cases.
Anyone with information related to the fires can contact state police in Rockingham at (802) 875-2112. Information can also be provided by calling the Vermont Arson Tip Line at 1-800-32-ARSON.
There is up to a $5,000 reward for information resulting in an arrest.
