There is a persistent story that Lanza did not use an AR in ths massacre. The delay in getting this out and the security around the children’s autopsies have fueled this story.
IIRC it was an AR
What is the current status of the theories that this whole Lanza massacre was a HOAX? I know that possibility seems incredible, but if they could falsify the explanation for the shoot-down of TWA flight 800, with hundreds of families of victims, AND hundreds of eyewitnesses, they could easily fake or cover up the killing of two dozen or so with there related families.
