Gunman Adam Lanza wore yellow ear plugs that muffled the screams of his victims at Sandy Hook Elementary School and he shot himself in the mouth after committing one of America's worst school massacres.
On December 14, 2012, a man wearing combat gear and armed with semiautomatic pistols and a semiautomatic rifle entered Sandy Hook Elementary School in the Sandy Hook village of Newtown, Connecticut, US, where he fatally shot 20 children and 7 adults. The gunman, identified as Adam Lanza, age 20, most likely shot and killed himself during the incident. The gunman had earlier shot and killed his mother at their residence prior to the shooting at the school. Lanza's girlfriend has also been reported missing in New Jersey.
