Adam Lanza, the 20-year-old who murdered 7 adults and 20 young children in Newtown, Conn. before turning the gun on himself learned to shoot from his mother, a family acquaintance said.
Dan Holmes worked as a landscaper for the Lanza family, he told the New York Daily News. Holmes recounted that Adam Lanza's mother, Nancy Lanza, collected guns and enjoyed taking her children target shooting.
The weapon used in the school shooting, a Bushmaster .223-caliber, was reportedly registered in Nancy Lanza's name. Two other guns were found in the school, a Glock 10 mm and a Sig Sauer 9 mm.
The Lanza family releases a statement.
