Concord, NH – Attorney General John M. Formella announces that Eric Sweeney (Age 17), formerly of Northfield, has been indicted by the Merrimack County Grand Jury in connection with the murders of his sister-in-law, Kassandra Sweeney (Age 25), and his nephews, Benjamin Sweeney (Age 4) and Mason Sweeney (Age 23 months) on August 3, 2022, in their Northfield home.

The Grand Jury has indicted Eric Sweeney on three counts of first-degree murder for purposely causing the deaths of Kassandra, Benjamin, and Mason Sweeney, by shooting them. Eric Sweeney was also indicted on one count of falsifying physical evidence, which alleges that Eric Sweeney, knowing that an investigation was about to be instituted, did alter, destroy, conceal, or remove a Taurus .40 caliber handgun, with the purpose of impairing its availability in said investigation.

The defendant is currently being held. An arraignment will be scheduled by the Court.

The charges and allegations set forth in the indictments are merely accusations, and the defendant is presumed innocent unless and until proven guilty.
