Police Account of the Crash and Response

Nassau County Police said the driver, identified as 40-year-old Allison Rahmani, lost control of a 2023 GMC on a Hewlett Bay Park driveway on August 21 at about 9:29 a.m. The SUV struck a tree and an unoccupied 2006 Honda before entering an inground pool, where it became submerged. First responders removed Rahmani and performed lifesaving measures. She was taken to a local hospital and pronounced dead, according to the department’s account and local reporting.

Reports citing police say Rahmani managed to call 911 from inside the submerged vehicle before responders removed her and transported her to the hospital. The sequence of impacts, immersion, and rescue attempts was summarized in brief police statements to media. Authorities said the investigation continued after the crash. Officials did not release a detailed crash diagram, reconstruction file, or a definitive public cause of the medical or mechanical factors that may have preceded the loss of control.

Family Details and Final Text Messages

Rahmani was a mother of four and a teacher connected with the Hewlett and Five Towns community. The Long Island Herald identified her as a teacher and math coordinator at the Hebrew Academy of the Five Towns and Rockaway, where colleagues mourned her death. Her husband, Matthew Rahmani, told national media that their last exchange was light and warm. He texted, “I’m feeling so good,” and she replied, “LOL,” on the morning of the crash, according to his account and screenshots he shared.

People magazine reported that Nassau County Police described the crash path and the emergency response, while the family shared personal details about her life and community ties. The texts offer a human window into the morning’s routine but do not show what happened inside the vehicle. They do not prove a medical issue, distraction, or a mechanical fault. They do show a normal, affectionate rhythm in the couple’s daily communication before the sudden crash.

Cause Remains Under Investigation, With Known Gaps

Police and local press reported that officials had not publicly released an exact medical cause or a full reconstruction that explains why the SUV left its path. Some outlets referenced a suspected medical event, but no autopsy or toxicology findings have been made public in the reports reviewed. That means the most certain facts are the vehicle’s path, the immersion, the rescue efforts, and the confirmed death, while the trigger for the loss of control has not been disclosed.

This kind of case often hinges on physical evidence, emergency records, and vehicle data. Event data recorders, which many late-model vehicles have, can capture speed, brake use, and other details in the seconds before a crash. Investigators often use this data with scene measurements and medical findings to explain unusual loss-of-control events. National Highway Traffic Safety Administration materials describe how these tools help reconstruct what happened when human memory and stress leave gaps.
