Incident location, Long Island
What Happened
A 15-year-old boy was struck and killed by a motorist on the Southern State Parkway in North Valley Stream on Thursday afternoon, September 4, 2025, in a fatal crash that has left both a Queens family and an Elmont school community in mourning. According to Newsday, the victim has been identified as Christopher Williams, a resident of Saint Albans, Queens, who attended Martin de Porres School for Exceptional Children in Elmont.
The crash occurred at approximately 1:13 p.m. while Williams was in the eastbound lanes of the Southern State Parkway, between exits 13 and 14, according to Trooper Brittany Burton, a spokesperson for New York State Police Troop L, which patrols Long Island. Williams was struck by a motorist under circumstances that state police said were not immediately made clear, including details about the driver involved and exactly how the teen came to be on the high-speed parkway. He was transported to Long Island Jewish Valley Stream hospital following the collision, where medical staff pronounced him dead.
Newsday reported that a spokesman for Martin de Porres School for Exceptional Children confirmed that Williams had left the school campus during school hours before the crash took place. Nassau Police Det. Tracey Cabey said the school contacted police around 1:30 p.m. — approximately 15 minutes after the accident occurred — to report a missing student. According to Cabey, the description provided by the school of the missing student matched the description of the individual police observed on the parkway, allowing authorities to make the connection between the two incidents.
The school’s executive director, Joe Trainor, issued a written statement in response to the tragedy. “We take this incident very seriously and, working with our board, have already begun a top-down review of our internal procedures and policies,” Trainor wrote in an email to Newsday. Trainor did not elaborate on the specific circumstances that led to the student being on the parkway. He went on to say: “The Martin De Porres family is heartbroken at the loss of one of our students, and our entire community is grieving today. We extend our deepest condolences to the student’s family, friends, and loved ones.” Trainor confirmed that counseling and support services were being made available to students and staff in the wake of the tragedy, and asked for privacy so the school community could grieve and begin to heal.
In describing the school’s broader mission, Trainor added: “The mission of The Martin De Porres is to educate children experiencing emotional and behavioral problems, and through that education, we strive for every child to have the opportunity to reach his or her fullest potential. We will always stay true to those core values and put the health and education of our children first.” Williams’ family could not be reached for comment.
During the police investigation at the crash scene, three left lanes of the eastbound Southern State Parkway were closed in the area. Those lanes were later reopened, according to the New York State Department of Transportation. State police have confirmed they are continuing to investigate the crash, with Trooper Burton serving as the official spokesperson for Troop L on the matter. No information regarding the driver — including whether any charges had been filed — was immediately made available.
Location & Road Context
The crash took place on the Southern State Parkway in North Valley Stream, one of Nassau County’s most heavily traveled arterial parkways. The specific stretch where Williams was fatally struck — the eastbound lanes between exits 13 and 14 — runs through a densely developed portion of southwestern Nassau County, and the roadway carries tens of thousands of vehicles daily. Pedestrians are prohibited from the parkway, as it is a limited-access highway without sidewalks, shoulders designed for foot traffic, or marked crossings between exits.
The Southern State Parkway has a significant and sobering safety record. Our database shows 446 recorded incidents on this road, ranging from minor crashes to serious collisions. Recent incidents include multiple crashes in May 2026 and ongoing utility and repaving work that has periodically reduced lane capacity along the corridor. The frequency of incidents on this road underscores its danger to any individuals who find themselves on the roadway outside of a vehicle.
Investigation & Legal Proceedings
New York State Police Troop L is actively investigating the circumstances surrounding the fatal crash, according to Trooper Brittany Burton. As of the initial reporting, the details surrounding the motorist — including the driver’s identity, whether any charges were filed, and the precise sequence of events leading to the collision — had not been released. Nassau County Police were also involved peripherally, as Det. Tracey Cabey confirmed that the department received the missing student report from the school at approximately 1:30 p.m. and connected that report to the crash scene. Anyone with information about the incident is encouraged to contact New York State Police.
Broader Impact
The death of Christopher Williams raises serious questions about supervision and safety protocols at schools serving children with emotional and behavioral needs. Martin de Porres School for Exceptional Children’s executive director acknowledged the school had already launched a top-down review of its internal procedures and policies in the immediate aftermath of the tragedy — an acknowledgment that how a 15-year-old student was able to leave campus undetected and reach a restricted limited-access parkway is a question that demands answers. The school’s stated mission is to ensure “every child” reaches their fullest potential; for families in communities like Saint Albans who trust these institutions with their children, that mission carries the weight of a sacred obligation.
