The Westchester County community is mourning the loss of Joan A. Mosca, a 92-year-old resident of New Rochelle, whose disappearance ended in tragedy after she was found deceased inside her overturned vehicle following an extensive missing person search.
According to the New York State Police, the investigation began at approximately 7:30 p.m. on June 30, when Mosca’s family reported her missing. She had last been seen around 4:00 p.m. leaving a park-and-ride lot near Exit 4 of Interstate 684 in Mount Kisco.
Authorities said she was observed driving her gray Toyota Camry southbound on Interstate 684 before contact with her was lost. Concerned for her safety, law enforcement agencies launched a coordinated search of the interstate corridor, focusing on likely travel routes, exits, and areas where a vehicle could have left the roadway.
At approximately 10:30 p.m., investigators located Mosca’s overturned vehicle about 30 feet off the shoulder of southbound Interstate 684 near mile marker 0.9. Emergency responders immediately rushed to the scene after the vehicle was discovered.
First responders found Joan A. Mosca inside the vehicle. Sadly, she was pronounced dead at the scene.
The New York State Police continue to investigate the circumstances surrounding the fatal crash. Preliminary information indicates the incident was a single-vehicle collision, but officials have not yet determined or released the official cause of the accident.
Investigators are examining roadway conditions, vehicle dynamics, and any potential mechanical or environmental factors that may have contributed to the crash. Accident reconstruction specialists are also reviewing evidence collected from the scene to establish exactly how the collision occurred.
Following confirmation of her identity, authorities notified Mosca’s family, bringing a heartbreaking end to the search effort.

Those mourning her loss are remembering a life that spanned more than nine decades while offering heartfelt condolences and support to her loved ones during this difficult time.
Funeral and memorial service arrangements have not yet been publicly announced. The Mosca family is expected to share additional details once arrangements have been finalized.
