HARTFORD, Conn. (WTNH) — Family members of nine victims and one survivor of the massacre at Sandy Hook Elementary School are asking the highest court in the state to hear their appeal.

The families’ case against Remington Arms, the gun maker that manufactured the AR-15 used by Adam Lanza in the 2012 shooting, was struck down by a Superior Court judge in Bridgeport in October. The suit alleges that the AR-15 used in the shooting was negligently entrusted to the public, and that Remington violated the Connecticut Unfair Trade Practices Act in ‘aggressively and unethically marketing the AR-15 to the public.’

In October, Judge Barbara Bellis dismissed the case under the federal Protection of Lawful Commerce in Arms Act, which shields gun makers from liability when their firearms are used in crimes.

“We feel strongly that the critical issues raised in this case belong before our state’s Supreme Court and we hope the Court agrees,” said the families’ attorney, Josh Koskoff of Koskoff, Koskoff & Bieder. “The Supreme Court not only sets precedent but also reviews the applicability and relevance of prior decisions, and works to ensure that the common law is up-to-date with the realities and dangers of a changing world.”

Besides Remington, other defendants in the lawsuit included firearms distributor Camfour and Riverview Gun Sales, a now-closed East Windsor store where Lanza’s mother Nancy, legally bought the Bushmaster XM15-E2S rifle used in the shooting.
