Maine residents have turned in dozens of unwanted guns in a donation program that raises money for a charitable cause. A total of 68 guns and bags of ammunition were turned in at Cumberland, Falmouth, and Yarmouth police departments and at the State Police barracks in Gray on Saturday. The guns will be sold and the proceeds donated to Special Olympics Maine. The event was organized to help reluctant gun owners, such as hunters’ widows, who don’t know what to do with the weapons, the Portland Press Herald reported. The program was a success, said Maine State Police Sergeant Michael Edes, who said more than two dozen people expressed relief when they dropped off donations in Gray. A number of the donations were quite valuable, including a World War II-era rifle, a pearl-handled revolver, and 100-year-old single-barrel shotgun, Edes said. Guns that are no longer usable will be destroyed, Edes told the Press Herald.
