A New Hampshire man, Eric Sweeney, 19, has pleaded guilty to the second-degree murder of his sister-in-law and two nephews, court proceedings on Friday disclosed. Now 19, Sweeney was residing with his brother's family in Northfield where the fatal shootings of Kassandra Sweeney, aged 25, and her sons, 4-year-old Benjamin and 1-year-old Mason, took place in August of 2022. A report by NBC Boston detailed that Eric Sweeney has entered this plea ahead of what was to initially be a trial on first-degree murder charges next month.
During the court hearing, Sweeney communicated only to confirm his understanding promptly, facing a possible life sentence at his sentencing scheduled for October 3rd. Before the tragic event, tensions were reported to have escalated due to Sweeney's "increasing behavioral issues," leading to his older brother Sean and Kassandra serving as his guardians to take precautionary measures, including locking doors to secure certain areas of the home as explained by Assistant Attorney General Bethany Durand and noted by Boston 25 News. Durand recounted that on the morning of the murders, Kassandra Sweeney created video clips of her sons playing, completely unaware of the forthcoming danger.
The details surrounding the case grew darker as the investigation unfolded. According to court documents, the children and their mother suffered fatal gunshot wounds to the head, with young Benjamin still adorned in his dinosaur costume. The weapon used, a handgun, belonged to Eric's brother and had been stored under lock and key. These findings contradicted Eric's initial statements upon detention where he claimed to have heard a break-in and discovered the victims after the fact, as described by Durand in statements obtained by NBC Boston.
Prior to the murders, Sean Sweeney had already expressed safety concerns for his family to police, citing the unsettling behavior of a person in their home, who was later identified as Eric. Court documents further revealed that Sean had found a weapon in the garage and more in the woods barely two weeks before his wife and children were tragically killed. Eric Sweeney, whose defense team once contemplated an insanity plea, is to now await his sentencing for a crime that has deeply shaken the local community, as mentioned in a report by Boston 25 News.
Lawyers of both parties also declined to release statements. Eric Sweeney's written note to his family, discovered after he unlawfully took their truck in June 2022, echos a chilling prelude to the harrowing events that were to unfold. "I do not belong in this family All I do is steal and lie and be irresponsible," he inscribed, concluding with, "I love you big bro and sis bye," further delineating the personal turmoils as reported by NBC Boston.
