On the morning of August 3, 2022, a 911 call brought police to a home on Wethersfield Drive in Northfield, New Hampshire, where three family members were found dead. Twenty-five-year-old Kassandra Sweeney and her sons — four-year-old Benjamin and one-year-old Mason Lee Sweeney — each died of a single gunshot wound, and the medical examiner ruled all three deaths homicides.

Authorities said they had identified all individuals involved and that there was no ongoing threat. The children’s father and Kassandra’s husband, Sean Sweeney, cooperated with investigators and issued a public statement about his grief and responsibility to preserve their memories.

A juvenile was taken into custody in connection with the killings and was charged with three counts of first-degree murder and one count of falsifying physical evidence. That teen, identified later as Eric Sweeney, was indicted by a Merrimack County grand jury; the indictment includes an allegation that the .40 caliber handgun used in the deaths was disposed of to impede the investigation. The suspect is being held without bail as proceedings continue.

If anyone knew Kassandra, Benjamin, or Mason, or has information about that day in Northfield, please come forward.
