(NPR) A Connecticut judge has dismissed a lawsuit that was filed against the manufacturer and seller of the weapon used in the mass shooting at Sandy Hook Elementary School in 2012.

The dismissal comes months after a judge allowed the case to proceed against Remington Arms, maker of the Bushmaster AR-15 rifle, as well as the distributor and seller. The families sought damages and relief in their lawsuit, arguing that the weapon that Adam Lanza used to kill 26 people, including 20 children, at Sandy Hook should never have been sold in the civilian marketplace.

In addition to Remington, the lawsuit named firearms distributor Camfour as well as Riverview Sales, the company that owned the gun store, saying that the defendants had violated both federal and state laws that cover lawful commerce and trade practices.
