Two men are now under arrest in connection with what authorities are calling a deliberately set fire at a former paper mill in Gardiner.On Tuesday investigators from the State Fire Marshal’s office and Gardiner Police held a news conference, announcing they’ve found the two people they believe are responsible for the fire.Officials say 19-year-old Jack Downs of Chelsea and 20-year-old Joshua Lund of Gardiner were arrested Monday night.They’re charged with arson in connection with last week’s fire that partially destroyed the former paper mill on Water Street.Currently four tenants lease that building.The state fire marshal says teamwork with local fire officials and police helped nab the suspects. “It’s invaluable to have their help. We do not have the volume of investigators in our office that can do the same amount of work in the same amount of time as we’ve done here,” Said State Fire Marshal John Dean. “I’m just glad they’re off the streets and won’t be able to do it anyone else,” The building’s owner, Paul Rheaume told TV 5. “This is something that people don’t normally go through it’s quite a daunting task to get through it.” Both men are also charged with burglary.They were taken to the Kennebec County Jail in Augusta. Bail has been set at fifty thousand dollars each.
