MAMARONECK, N.Y. (May 6, 2025) — Village of Mamaroneck Police Department officers safely resolved a domestic incident involving a knife-wielding man on Sunday, May 4, 2025, at approximately 6:07 p.m., according to authorities.
Police responded to a local residence after a 26-year-old woman reported that her brother, Jorge Cerna, a 28-year-old Mamaroneck resident, was intoxicated and threatening her with a knife. The caller had locked herself in a room, unable to leave due to Cerna’s violent behavior.
Upon arrival, officers found Cerna armed with a knife and threatening to harm himself and the responding officers. For about 10 minutes, police attempted to de-escalate the situation, urging Cerna to surrender peacefully. During the negotiation, Cerna placed the blade to his throat and approached officers with the knife, prompting them to use a Taser. The Taser temporarily incapacitated Cerna, allowing officers to take him into custody safely.
Emergency Medical Services transported Cerna to White Plains Hospital for medical treatment and psychological evaluation. No family members or officers were harmed during the incident.
Cerna faces charges of Unlawful Imprisonment First Degree, an E Felony, and Menacing Second Degree, an A Misdemeanor, under New York State’s mandatory Family Offense provisions. He is currently held in a secure psychiatric facility. Upon release, Mamaroneck police will process and arraign him, and a Temporary Order of Protection will be issued.
