Teenager Charged with Triple Homicide of Mother and Two Young Sons

Prosecutors have charged Eric Sweeney, a 17-year-old teenager, with three counts of first-degree murder and one count of falsifying evidence in connection with the triple homicide of his sister-in-law, Kassandra Sweeney, and her two young sons, Benjamin and Mason Sweeney. The incident occurred on August 3, 2022, at their home in Northfield, Massachusetts.

According to court records, Kassandra Sweeney sent Snapchat videos of her two sons to her husband, Sean Sweeney, shortly before the killings. Less than 10 minutes later, Eric Sweeney allegedly shot and killed Kassandra and her sons.

Location data from Kassandra’s phone indicated that it started moving away from her home just before 11 a.m. Eric Sweeney reportedly sent messages from Kassandra’s Snapchat account to Sean, saying “Help. It’s Eric.” Sean called 911 and reported that someone had broken into their home and killed his family.

Police arrived at the scene and discovered the three victims dead in the kitchen. Autopsies revealed that each victim had died from a single gunshot wound. Eric Sweeney, who lived with his brother’s family, arrived at the scene shortly after the police.

During the investigation, Eric Sweeney claimed that he had been in the basement when he heard yelling and gunshots. He said he found the victims on the kitchen floor and took Kassandra’s keys and phone before leaving the basement. Sean had previously reported concerns about Eric’s behavior to the police in July 2022.

Investigators found that Sean’s gun safe, which contained two handguns, was unlocked and missing one gun and a magazine. The alleged murder weapon was later found on the side of the road, along with the key to the gun safe, near where Eric had driven away from the scene. Gunshot residue was also discovered on Eric’s hands and the steering wheel of the truck he used.

Prosecutors have not yet provided a motive for the triple homicide. Eric Sweeney’s lawyer declined to comment on the case.
