In response to:
There should be absolutely no question about weapon(s) was used since there had to be shell casings everywhere. Why haven't we heard anything about what caliber they were?
Earlier today I posted an NBC News report about the type of weapons Adam Lanza used during his Sandy Hook rampage. That report was from December 15 and contained false information. According to the Newtown coroner, Lanza used a semi-automatic AR-15, not four handguns as the report said. The entire post has been retracted. I apologize for the error.
“A law enforcement source told CBS News’ Pat Milton that casings (spent shells) from a .223 semi automatic rifle were found inside the school.”
From ABC News:
“A Sig Sauer handgun and a Glock handgun were used in the slaying and .223 shell casings — a round used in a semi-automatic military style rifle — were also found at the scene. ”
