Newtown, CT, United States (4E) – Investigators are looking into the gun and computer use of the 20-year-old man who killed six adults and 20 children in a school in Newtown, Connecticut last weekend.
Authorities have determined that Adam Lanza managed to enter Sandy Hook Elementary School after he started firing into the entrance of the facility.
Multiple magazines, each one with 30 bullets, was used by Lanza from a Bushmaster AR-15 rifle to murder 26 people. The victims were shot several times before the gunman killed himself using a handgun.
Officials are also checking the ruined home computer of Lanza in the hopes that e-mails and websites he visited would give clues about his motive.
Lanza’s history with firearms is also being investigated. Three weapons were discovered near his dead body included the semiautomatic Bushmaster .223-caliber rifle and two handguns from Glock and Sig Sauer, while another shotgun was found in his car, revealed Connecticut State Police Lt. J. Paul Vance.
The Bureau of Alcohol, Tobacco, Firearms and Explosives spokeswoman Debora Seifert said Monday that the weapons are owned by his mother, Nancy Lanza, who was found shot dead in her Newtown home Friday.
The mother is a firearm collector, who shot them and went to gun ranges. She visited the range together with her son.
Vance added that hundreds of law enforcement personnel are examining every round of ammunition fired, checking the gunman’s medical history and interviewing witnesses.
Investigators also plan to talk to two unidentified adults wounded during the shooting.
