I snoped the bejesus out of this issue months ago. He used the AR to kill the kids and teachers and all major news agencies continue to report this.

AND....at the end of the IJ review article dated 1/15/13, it states this:
"Editor’s note: Connecticut State Police have confirmed that Adam Lanza did, in fact, use a Bushmaster .223 high capacity rifle and two hand guns. As far as we can tell, NBC has not issued a retraction."

The link to the IJ review is very old and story was when details were still emerging...not to mention the rumors and conspiracy theories floating around to contend with.
