MERIDEN/NEWTOWN, Conn. - The gunman who killed 20 children and six adults at a Connecticut elementary school fired 154 rounds in less than 5 minutes, selecting high capacity magazines from a home arsenal stocked with swords, knives and a cache of guns, officials said.
Investigators also found a newspaper clipping about a mass shooting in the home that Adam Lanza shared with his mother, along with a gun safe in his bedroom, receipts from shooting ranges and National Rifle Association certificates for both of them, according to court papers released on Thursday.
To carry out the second deadliest school shooting in US history, Lanza used 30-round magazines at Sandy Hook Elementary School in Newtown, said Connecticut Governor Dannel Malloy after the previously sealed searches of Lanza's car and home were made public.
"We now know that he left the lower capacity magazines at home," Malloy said in a statement. "This is exactly why we need to ban high capacity magazines and why we need to tighten our assault weapons ban."
