A man who was just 16 when he murdered his sister-in-law and two young nephews is set to face a sentencing hearing this Friday, with prosecutors seeking a minimum of 97 years in prison.
Eric Sweeney, now 19, had been living with his older brother’s family in Northfield for three years before he fatally shot Kassandra Sweeney, 25, and her sons, Benjamin, four, and Mason, 23 months, in August 2022.
