The incident took place in the city of Newtown, Connecticut, in 2012. The perpetrator, 20-year-old Adam Lanza, used the AR-15 automatic weapon during the act. After the massacre, Lanza shot himself. Later, his mother was also found dead in their communal home.

In 2014, a number of relatives joined the victims of the school massacre and sued gun manufacturer Bushmaster Firearms, which is owned by Remington. According to the sentiment, the AR-15 automatic weapon should never have been sold to the public, as it was manufactured for military use.

Remington's appeal was rejected

"Time and time again, mentally unstable persons and criminals have easily accessed the AR-15 and been able to unleash the deadly force of the rifle on our streets," it said in documents submitted to the court.

Remington, in turn, appealed against the lawsuit, but on Tuesday, HD announced that the weapons company's request would be rejected, giving the victim's relatives the right to pursue their lawsuit.
