Sandy Hook families settle with gunmaker Remington over school massacre

The families of nine victims of the 2012 Sandy Hook school shooting have reached a settlement with Remington, the maker of the rifle used in the massacre, according to US court documents released Tuesday.

Twenty-six children and teachers were shot dead at the elementary school in Newton, Connecticut by 20-year-old gunman Adam Lanza, who then killed himself.

A "settlement agreement has been executed between the parties," the notice from lawyers for the families said.

US media reported that the settlement amount was $73 million. 

The lawsuit had alleged that Remington and the other two defendants are culpable because they knowingly marketed a military grade weapon that is "grossly unsuited" for civilian use yet had become the gun most used in mass shootings.

The plaintiffs alleged that the gun was marketed immorally and unscrupulously, sold on its war-fighting capabilities to civilians.

Marketing, they alleged, popularised the AR-15 in combat and mass shooting-type situations through the type of violent video games that Lanza was known to play.

They specifically cited Remington's marketing of high-capacity magazines, which have only combat utility, for use with the gun.

Last year a US judge ruled in favour of parents who sued conspiracy theorist Alex Jones for saying that the massacre at the school was a hoax.

In the shooting, 20 six- and seven-year-old children and six staff members were killed. Earlier, Lanza had also killed his mother at their Newtown home.
