Mount Kisco became the focus of a grim search late Wednesday after a 92-year-old woman who left the I-684 park-and-ride never made it home. Hours later, troopers discovered her gray Toyota Camry overturned about 30 feet off the southbound shoulder of the highway, and the driver was pronounced dead at the scene.
Authorities say the vehicle went off the right shoulder, hit a tree and overturned. The cause of the crash is still under investigation.
State police confirm timeline and identity
According to New York State Police, troopers opened a missing-person investigation at about 7:30 p.m. on June 30, after the woman was last seen around 4 p.m. leaving the park-and-ride at Exit 4 in Mount Kisco.
State Police say troopers found the overturned Camry at about 10:30 p.m. near mile marker 0.9 on southbound I-684 and identified the driver as Joan A. Mosca, 92, of New Rochelle. The agency reported that Mosca’s car exited the right shoulder, struck a tree and overturned. Harrison EMS and the Westchester County Medical Examiner responded and assisted at the scene.
Local outlet published the initial account
As reported by Daily Voice, the information released so far comes from the State Police statement and was first picked up by regional reporters. The outlet noted that little public information about Mosca’s life was immediately available and that authorities have not yet said whether a medical issue, mechanical problem or some other factor may have contributed to the crash. Daily Voice listed the State Police bulletin as the primary source for the developing story.
Investigation remains active
State Police say the crash investigation is ongoing as troopers work to piece together what happened along the southbound stretch of I-684. No charges have been announced, and officials have not released any additional findings. Per the agency’s notice, anyone with information that could help the case is asked to contact State Police.
What neighbors and commuters should know
The wreck took place along a heavily traveled commuter corridor of I-684 near Exit 4, which serves a busy park-and-ride lot. Authorities have emphasized that details are still preliminary and asked the public to be patient while investigators work to determine how and why the vehicle left the roadway.
