Man Who Sold Gun Used In Newtown Shooting Faces One Year In Prison

    Former Connecticut gun store employee Krystopher Dibella pleaded guilty in federal court to selling the assault rifle that Adam Lanza used in the Sandy Hook Elementary School massacre.

    Krystopher Dibella, 25, of West Suffield, Conn., who sold the Bushmaster AR-15 assault rifle used in the Sandy Hook elementary school shooting, faces up to one year in prison after pleading guilty to federal gun charges, BuzzFeed has learned. He also may be fined $100,000 and put on probation for five years.

    Dibella, a former employee of Riverside Gun Sales in East Windsor, Conn., was charged with aiding and abetting a failure to make a proper entry on an ATF 4473 form, which is a firearms transaction form. The offense occurred on March 15, 2010, the same date Nancy Lanza began the purchase of the rifle used by her son Adam Lanza in the Sandy Hook massacre, the Journal News reported.

    Riverside Gun Sales was shut down by the Bureau of Alcohol, Tobacco, & Firearms in April after more than 500 federal violations were uncovered. The Journal News confirmed in April that Nancy Lanza had purchased the Bushmaster AR-15 assault rifle at Riverview Gun Sales on March 29, 2010.

    "If the ATF had been properly staffed, and funded, perhaps gun stores and their employees wouldn't be allowed to operate after repeated violations," Dave Ackert, founder of the Newtown Action Alliance, told BuzzFeed.

    Dibella will be sentenced on September 16 in Bridgeport, Conn.

    Here are the court documents detailing the charges and sentencing Dibella faces.
