The elementary school shooting left 20 students and six adults dead. The settlement is thought to be first of its kind, awarding major damages against a U.S. gun manufacturer based on a mass shooting.

Founded in 1816, Remington Firearms is one of the United States’ largest producers of shotguns and rifles. Several of the company’s strategic products will be manufactured in Georgia. The new headquarters will also become home to an innovative research and development center.

The settlement proposal is far lower than what families said they expected. But an attorney with more than 20 years of experience working with mass shooting victims says there's a lot to think about.
