During North Andover’s first gun buyback program, held at the Police Department earlier this month, police collected 27 unwanted pistols, rifles, and shotguns, according to Police Chief Paul J. Gallagher. Police also collected several BB guns and nonfunctioning guns, he said. In all, $1,350 worth of gift cards were distributed in exchange for the weapons. However, several residents turned down the offer of a gift card, saying they just wanted to get rid of the guns, Gallagher reported. He is recommending that the sponsors of the gun buyback, local residents Phil Rohn and his wife, Judy, be honored by the Board of Selectmen for their contribution to the community. The Rohns offered to donate up to $2,600 — a $100 tribute for each victim of the Sandy Hook Elementary School shootings in Connecticut — to collect unwanted weapons from North Andover residents. Rohn, who supports the Second Amendment right to bear arms, said the Dec. 14 shooting in Newtown, Conn., inspired his family to take action in hopes of making a difference.
