(FILES) Photo dated December 13, 2013 shows a memorial to victims of last year's Sandy Hook elementary school victims in front of a house in Newtown, Connecticut.
New York:
Newtown gunman Adam Lanza wore yellow ear plugs that muffled the screams of his victims and he shot himself in the mouth after committing one of America's worst school massacres.
Disturbing details about last year's mass shooting were revealed yesterday when US police released thousands of pages of documents, photographs and recordings from their investigation.
The troubled 20-year-old shot dead 20 first grade children and six adults at Sandy Hook Elementary School, using a rifle taken from his suburban mother's legally acquired home defense arsenal.
Lanza was dressed almost entirely in black, his clothes - a shirt, T-shirt, cargo pants, boxer shorts, socks, sneakers, belt and fingerless gloves - found spattered with blood and gunpowder after the murders.
"Two law enforcement officers arrived during the shooting, at which time the suspect ducked into a classroom and shot himself," according to an FBI incident report contained in the file.
Lanza shot himself in the mouth, shattering his brain and skull, according to the attached forensics report.
The documents are the latest pieces of chilling evidence that expose some of the horror that Lanza's victims endured on December 14, 2012 in the small Connecticut town.
The massacre, just one in what was then a series of deadly shooting sprees across the country, inspired a short-lived and ultimately failed drive to tighten US gun ownership rules.
According to at least one witness interviewed by the FBI, Lanza and his mother Nancy owned at least four firearms, which were kept in a gun safe in the school shooter's bedroom closet.
Witness testimony, which has been redacted to remove names and other identifying details, also revealed little known details about Lanza, who suffered from Asperger's Syndrome.
The gunman was a vegan, interested in Japanese techno music and had been taking Chinese lessons. He also knew how to build a computer from scratch by assembling the spare parts.
His mother at one point took him out of school because he was sensitive to sound and light and photographs showed various windows taped over with white plastic and black bin Liners.
One door in the house was also shown taped shut.
