The New Hampshire State Police is releasing additional information regarding a fatal crash that occurred yesterday on Interstate 93 in Windham.
On June 4, 2024, at 9:54 a.m., State Troopers from the Troop B and Troop G barracks responded to I-93 in the area of mile marker 5.6 for a report of a rollover crash involving serious injuries. Troopers responded, along with fire and medical personnel from the Windham Fire Department. Upon arrival, a white GMC Envoy was located on its side and partially in the left lane of I-93 North. The driver of the Envoy, identified as Matthew Woo, 51, of Allenstown, had been thrown from the vehicle and was pronounced deceased.
