Gun shop that sold to mother of Newtown shooter loses license Fri Apr 5, 2013 5:27pm EDT (Reuters) - The U.S. Bureau of Alcohol, Tobacco and Firearms said on Friday it had revoked the federal license of a Connecticut gun retailer that sold a weapon to the mother of Adam Lanza, who killed 26 people at an elementary school in December. The agency on December 20 revoked the license of Riverview Gun Sales in East Windsor, Connecticut, ATF spokeswoman Debora Seifert said. The revocation was reported in The Journal News, of Westchester County, New York, on Friday. "We did revoke their federal firearms license," she said. The agency did not publicly disclose a reason for the closure. A woman who answered the telephone at Riverview on Friday, and did not give her name, confirmed the store had sold a weapon to Lanza's mother, Nancy, and that its license had been revoked. She declined further comment. Nancy Lanza was her son's first victim in the December 14 attack. He shot her in their family home before driving to Sandy Hook Elementary School, Newtown, where he gunned down 20 young children and six adults before shooting himself dead. The weapons Adam Lanza, 20, used in the attack were all legally purchased and registered. Reporting by Scott Malone; Editing by Dale Hudson
