The Supreme Court is allowing families of Sandy Hook victims to proceed with a lawsuit against a gun manufacturer.

Gunman Adam Lanza opened fire at Sandy Hook elementary school with a Bushmaster AR-15 style rifle, killing 20 first-graders and six educators on December 14, 2012.

A survivor and relatives of nine victims filed a wrongful death lawsuit against Remington Arms in 2015, saying the gun manufacturer should have never sold such a dangerous weapon to the public, and alleges the company targeted younger, at-risk males in marketing and product placement in video games.

“The decision will have immediate and severe consequence exposing the firearms industry to costly and burdensome litigation,” said Remington representative in its petition to Supreme Court.

The Supreme Court order does not mean Remington or other gun manufacturers will face any immediate liability, but it sets up potential court battles over the gun industry’s responsibility for the Sandy Hook massacre and potentially open the door to other suits in relation to other mass shootings or murders.
