The Bureau of Alcohol, Tobacco, Firearms and Explosives are searching all gun shops in Connecticut to see if they were involved in any way with the shooting at an elementary school in Newtown last week.
Adam Lanza, 20, shot and killed his mother as she slept in her bed and then went to the school Friday morning where he proceeded to shoot and kill 20 children, between the ages of 6 and 7, and six adults before shooting himself in the head.
The weapons used in the second-deadliest school shooting in United States history included a Bushmaster AR-15 assault-type weapon with high capacity magazines, a Glock 10 mm and a Sig Sauer 9 mm.
All of them belonged to his mother, Nancy Lanza.
Adam Lanza had visited numerous shooting ranges and he went with his mother, sources said. Investigators have not found any evidence to suggest the visits to the gun ranges were recent.
Now, the ATF is searching gun shops and businesses in the region to see if they have any activity with Nancy and Adam Lanza.
Investigators have not done any forensic work on the guns or bullets at this point. They wouldn't elaborate to Eyewitness News on what they've found or what they specially are looking for.
However, investigators are still looking for leads when talking to local gun providers.
