We will have to wait for the coroner’s report to determine which weapons were used; however, nearly all reports indicate the AR15 was the primary weapon used.
Listening to this old news report, it brings up the matter of whether Lanza was denied permission to purchase a rifle in the days leading up to the crime and whether he had some altercation with the staff the day before. Supposedly, both matters were debunked in later reports, but why would someone make those items up at the time? Was it someone just passing on an unfounded rumor or is their information being withheld from the public? I don’t know. Curious that we haven’t hear much from the investigators for a while.
“Coroner’s report”?
Not sure of CT exactly but:
If such records were publicly available, one would make a request for each and inspect them in person, perhaps being allowed to pay a fee for copies of some documents. Death certificates are generally not available to the public.
I believe the ME has made several statements concerning only .223 wounds to the victims.
