BRIDGEPORT - The maker of the type of gun used at Sandy Hook and several other mass shootings won a partial victory in a Bridgeport courtroom Thursday.

The hearing is part of a lawsuit that several Sandy Hook families brought against Remington Arms.

Remington Arms is fighting to keep certain company documents related to the marketing of the AR-15 rifle secret.

The judge in the case said Thursday that she is willing to seal at least some of the documents from the public to protect the company's business interests.

Sandy Hook family members believe certain internal marketing strategies will prove AR-15 makers are negligently selling military-style weapons to civilians.

If they win, it could open gunmakers up to hundreds of wrongful-deaths all over the country.

The case will not go to trial for another two years, and lawyers say up to 1 million documents could be produced.
