A 68-year-old woman was struck and killed on the Everett Turnpike in Nashua Wednesday night by a vehicle that fled the scene, New Hampshire State Police said.

Juliette Koss of Nashua was pronounced dead at the scene of the crash, which occurred at 7:05 p.m. near the exit 4 off-ramp, State Police said in a press release.

State troopers first received a report that a pedestrian had either fallen or collapsed on the southbound side of the highway. “Within minutes of the original call it was then reported that the pedestrian had been struck by a vehicle,” the release stated.

Emergency personnel pronounced Koss dead at the scene, officials said.


They also determined that the vehicle had fled. Witnesses described the vehicle as a tan-colored mid-to-full size SUV-type vehicle.

“This vehicle should have damage to the front end and bumper area,” the release said.

Anyone with information about the vehicle should contact Trooper Daniel Quartulli at 603-223-8993 or at daniel.quartulli@dos.nh.gov.

The crash remains under investigation.
