A Concord woman died early Sunday morning in a single-car crash on Interstate 93 in the city.

Elisabeth Philbrick, 33, was pronounced dead at the scene of the crash, according to New Hampshire State Police. Philbrick’s 5-year-old son was a passenger in the car at the time. Police said the boy was uninjured but transported to Concord Hospital for evaluation.

The crash was reported Sunday at approximately 5:26 a.m. in the area of mile marker 42 on the southbound side of I-93. Dispatchers initially received a call about some debris in the roadway. When state troopers arrived, they found a 2018 Hyundai Elantra off the road, about 30 feet down an embankment and resting against some trees.

One lane of the highway was shut down for approximately five hours until the vehicle could be removed by emergency crews.

The cause of the crash remains under investigation, but investigators believe speed was a factor. Police ask anyone with information about the crash to contact Trooper Michael Petrillo at 603-223-8837 or by email at michael.petrillo@dos.nh.gov.
