Delaware Police Say DMV Trooper Killing Was Targeted Ambush by Man Claiming 'Gang Stalking'

Delaware State Police say their homicide unit has concluded that the Dec. 23, 2025 killing of Cpl. Matthew “Ty” Snook at the New Castle DMV was a deliberate, targeted attack on law enforcement carried out by 44‑year‑old Rahman Rose, who believed he was being monitored and harassed by police. Investigators say Rose, who had only limited, non‑criminal contacts with Delaware authorities and no prior interaction with Snook, twice entered the DMV that day before ambushing the trooper from behind at the reception desk and firing multiple shots as Snook shielded a DMV employee. Police say Rose had told others and posted on social media that he was the victim of 'gang stalking,' a belief that government or other entities are constantly surveilling and harassing an individual. A New Castle County officer fatally shot Rose through a window from outside the building after he allegedly allowed customers to leave but fired at responding law‑enforcement officers. Snook, a 10‑year veteran known as 'Ty,' is being publicly praised by state police for what they call a courageous act of sacrifice in protecting others during the attack. The case underscores growing concern among law‑enforcement officials about targeted ambushes motivated by conspiracy‑style grievances against police.
