In July 2026 a report noted that domestic murder convictions in New Jersey (alongside a separate case in Guyana) led to sentences ranging from 20 years to life imprisonment. Later that month, Atlantic County Superior Court Judge Joseph A. Levin sentenced Boris Lainez‑Rosales to 30 years without parole after the defendant pleaded guilty to the first‑degree murder of his pregnant girlfriend, Leslianette Quintana‑Betancourt. The sentencing reflected the brutality of the attack, which involved a baseball bat and resulted in severe injuries and a ruptured placenta.
