NEWTOWN, CT- Connecticut State Judge Barbara Bellis denied a motion to delay the discovery process in the lawsuit against gun companies over the Sandy Hook Elementary School mass shooting.

Bellis ruled that the discovery process should begin and that Remington Arms, the parent company of the AR-15 manufacturer would have to hand in internal documents and communications pertinent to the case. Firearm distributor Camfour Inc. of Massachusetts and Riverview Gun Sales of East Windsor were also named as defendants in the lawsuit. The lawsuit was brought by several family members of shooting victims.

"For almost a year and a half the families have waited patiently," said lawyer Josh Koskoff who is representing the families. "They have waited and watched as the defendants tried every tactic to avoid having to disclose a single document or answer a single question under oath. Now that wait is officially over." Related:
