LONDONDERRY, N.H. – A 17-year-old died from injuries sustained in a one-vehicle crash Friday afternoon on Interstate 93.

At 2:47 p.m. today, Aug. 23, 2024, State Troopers assigned to the Troop B barracks were dispatched to a crash near mile maker 14 on I-93 southbound. Troopers arrived and, after speaking with witnesses, determined a gray 2008 Mercury Milan was traveling southbound when it went off the interstate to the right-hand side and struck several trees.

The interstate was completely shut down for a brief period of time while members of the Londonderry Fire Department worked to extricate the driver from the vehicle. The driver, identified as Lillianna Cawthron, of Londonderry, was transported to Elliott Hospital in Manchester with life-threatening injuries. Cawthron ultimately succumbed to the injuries at the hospital.

The State Police was assisted at the scene by members of the Londonderry Police Department, Londonderry Fire Department and the New Hampshire Department of Transportation. Traffic was limited to two travel lanes for approximately four hours while the investigation was conducted and the vehicle was removed from the scene.

The investigation remains ongoing. Anyone with information that may assist the investigation is asked to contact Trooper Daniel Morton at (603) 223-4381 or Daniel.A.Morton@DOS.NH.GOV.
