Law-enforcement officials have determined that all of the weapons used by Sandy Hook shooter Adam Lanza were bought by his mother over a three-year period starting in 2010. Nancy Lanza purchased the .223-caliber Bushmaster semi-automatic rifle in 2010. In 2011, she added the 9mm Sig Sauer pistol to her collection. In January 2012, she bought the 10mm Glock. According to the Associated Press, authorities have recovered other weapons, including a Henry repeating rifle, an Enfield rifle, and a shotgun. Investigators also said it doesn’t appear that Lanza visited any shooting ranges leading up to the shooting.
