Gun Shop That Sold to Lanza's Mom Loses License ATF revoked license, no word yet on the reason By Newser Editors and Wire Services Posted Apr 5, 2013 10:05 AM CDT 251 comments Comments This undated identification photo released Wednesday, April 3, 2013 by Western Connecticut State University in Danbury, Conn., shows former student Adam Lanza. (AP Photo/Western Connecticut State University) (Newser) – A Connecticut shop that sold a gun to the Newtown school shooter's mother has lost its federal firearms license. The Bureau of Alcohol, Tobacco, Firearms, and Explosives revoked the license of Riverview Gun Sales in East Windsor, about 15 miles north of Hartford, in December. The agency didn't disclose why. It was first reported yesterday by the Journal News of White Plains, NY. Authorities raided the store for undisclosed reasons shortly after the December school shootings. Around the same time, a man was arrested for stealing a rifle from the shop. Shop owner David LaGuercia has said Nancy Lanza bought a gun from him years ago, but couldn't remember what kind. Adam Lanza used his mother's rifle in the massacre.
