Columbia, NH (June 21, 2026) – A 25-year-old woman lost her life, and five members of a family were injured following a head-on crash on Route 3 in Columbia on Friday night.
Rescue teams arrived at the scene around 9:00 p.m. on June 19, after receiving reports of a serious collision involving two vehicles. Preliminary findings indicate a 2012 Chevrolet Camaro was traveling northbound on Route 3 when it crossed the centerline and collided head-on with a southbound 2021 Chevrolet Silverado, causing severe damage to both vehicles.
The Camaro was driven by Courtney Diamond, 25, of Pelham. She suffered fatal injuries and was pronounced dead at the scene. The Silverado was occupied by two adults and three children from the same family. All five were initially taken to a local hospital before being transferred to another medical facility for additional treatment. Authorities reported that three of the occupants sustained life-threatening injuries.
Several passing motorists stopped to assist those involved before emergency personnel arrived. We extend our sincere condolences to the family of the deceased.
What Is Commonly Reviewed After a Head-on Collision?
Head-on crashes are among the most severe types of roadway accidents because the force of impact is concentrated between vehicles traveling in opposite directions. These incidents often result in significant vehicle damage and can lead to serious or fatal injuries for those involved.
After a head-on collision, investigators typically examine factors such as vehicle positions, roadway markings, speed, visibility conditions, and possible driver actions before impact. Physical evidence left on the roadway, including tire marks and debris patterns, may help establish how the crash unfolded. Investigators may also review vehicle data, witness statements, and any available video footage.
In crashes involving a vehicle crossing the centerline, attention is given to determining why the vehicle left its lane. Medical emergencies, impairment, distraction, fatigue, mechanical issues, and environmental conditions are among the factors to consider when reconstructing the events leading up to the collision.
