Eyewitness News has learned more about a Connecticut gun shop that sold two of the weapons found at the scene of the Newtown school shooting.

The attorney for Riverview Gun Sales told I-Team Reporter Len Besthoff that in March of 2010, the shop sold Nancy Lanza the AR-15 assault rifle her son used at Sandy Hook Elementary School

In March of 2011, store officials sold her a Sig Sauer handgun, which also found at the school where 20 children and six adults were shot and killed on Dec. 14.

Those sales, however are not what caused the East Windsor store to lose its federal firearms license.

The reasons Riverview Gun Sales lost its federal firearms license were laid out in a 12-page document by the Bureau of Alcohol, Tobacco, Firearms and Explosives.
