The six-year-old student who shot his teacher in the US earlier this year, boasted about the incident saying “I shot [her] dead”, unsealed court documents show.

While being restrained after the shooting at a Virginia school, the boy is said to have admitted “I did it”, adding “I got my mom’s gun last night”.

His teacher, Abigail “Abby” Zwerner - who survived - filed a $40m (£31.4m) lawsuit earlier this year.

The boy has not been charged.

The boy’s mother, however, Deja Taylor, has been charged with felony child neglect and misdemeanour recklessly leaving a loaded firearm as to endanger a child.

In Ms Zwerner’s lawsuit, filed in April, she accuses school officials of gross negligence for ignoring warning signs and argues the defendants knew the child "had a history of random violence

The documents also mention another incident with the same student while he was in kindergarten. A retired teacher told police he started “choking her to the point she could not breathe”.
