TUPPER LAKE — A fire was discovered outside the Franklin County District Attorney's Office in Tupper Lake just after 5 a.m. Wednesday.First Assistant Chief Mark Picerno said Tupper Lake Police found the blaze outside the building at 56 Lake St. in a corner where electric and phone lines connect."The Police Department got to it with fire extinguishers," Picerno said. "We came in and did the mop-up."No damage was done to the office or two apartments upstairs. "There is no interior damage whatsoever."But one resident of the building was home and asleep when police alerted the person to the blaze, Picerno said.The fire was not an arson, according to Franklin County fire investigators."It was not suspicious. We just don't have an actual cause due to the amount of damage in that corner," Picerno said.Three trucks and 45 firefighters responded to the fire call, using a thermal imaging camera, to check for hot spots, and about 100 gallons of water.The trucks were back in service by 11:11 Wednesday morning.
