Fire at 234 Fulton St. in Jamestown under investigation...
A Sunday morning fire extensively damaged a two-story, single-family home that had been condemned on Jamestown's northside.  City Fire Lieutenant Dan Balling says crews were called to the scene at 234 Fulton Street shortly after 7:30 a.m., and, found a lot of fire coming from the back of the building.  Balling says the lone occupant had suffered burns... but, had gotten out of the house, and was at a neighbor's house.  That burn victim was taken to UPMC Chautauqua Hospital for treatment.  He says crews were able to get inside the house and get the blaze under control in about 30 minutes.  He says two firefighters had to be treated for minor injuries.  An off-duty shift of 15 firefighters and one shift commander was called in.  Balling says the cause remains under investigation.  The Department of Development was called into determine the need for an emergency demolition.
