The families of nine victims of the Sandy Hook Elementary School shooting have agreed to a settlement of a lawsuit against the maker of the rifle used to kill 20 first graders and six educators in 2012. The families and a survivor of the shooting sued Remington over how it marketed the AR-15-style rifle used in the shooting and alleged the company targeted younger, at-risk males in its advertising. Remington had denied the allegations. A news conference was planned later Tuesday morning some of the plaintiffs.
