A quiet Mother’s Day afternoon in Riverhead turned deadly when police shot and killed a man who allegedly stabbed his own mother inside a home, according to authorities. Calls for help came in just before 3 p.m., and officers say the son was armed when they confronted him. His mother was rushed to a nearby hospital, though officials have not released her condition. Three Southampton Town Police officers were also injured in the encounter and were later treated and released.
What Officials Say Happened
Officers were called to a home on Topping Drive shortly before 3 p.m., where they encountered the son holding a weapon and fatally shot him at the scene, as reported by ABC7 New York. Police say the mother was taken to an area hospital, and three Southampton Town Police officers were evaluated and released after the confrontation. Detectives from the New York State Attorney General’s Office responded to the scene, and officials say the investigation is ongoing.
State Investigators Step In
Detectives from the New York Attorney General’s Office typically handle officer-involved shootings through an Office of Special Investigation that reviews body-worn camera footage, medical records and witness interviews. The AG’s OSI has previously outlined how it evaluates evidence and issues findings after a full review of an officer-involved death, according to the New York Attorney General’s Office. Those inquiries can take weeks or even months, depending on how much evidence there is to sort through.
What We Do Not Know Yet
Authorities have not released the names of the people involved or detailed the full sequence of events that led up to the stabbing and the shooting. No charges have been announced, and officials continue to describe the case as an active investigation. This story will be updated as investigators release additional information.
