Overview

• A sentencing hearing is set for Friday before Judge John C. Kissinger in Merrimack County Superior Court in Concord.
• Prosecutors ask for consecutive terms of 35 years to life for Kassandra Sweeney and 40 years to life for each boy, with up to 18 years suspended for education, treatment and behavior benchmarks.
• Defense lawyers request concurrent 40-years-to-life and plan expert testimony on juvenile brain development and a documented history of severe abuse and neglect.
• The case sits in unsettled New Hampshire law on de facto life-without-parole for crimes committed by juveniles, shaped by U.S. Supreme Court limits on mandatory LWOP.
• Court filings describe videos recorded minutes before the shootings and a murder weapon recovered eight days later along I-93; Sweeney also admitted falsifying evidence with an agreed suspended 3.5-to-7-year term.
