On Thursday, April 04, 2019, at approximately 4:40 PM, a solo vehicle collision with injuries was reported to 9-1-1, having occurred inside the Mount Tamalpais State Park. Reportedly a compact vehicle, occupied by two persons traveling westbound on Ridgecrest Boulevard in between Panoramic Highway and Fairfax-Bolinas Road in West Marin, for reasons unknown and remain under investigation, failed to negotiate a curve in the roadway near the Willow Camp Fire Road. The vehicle careened down a steep hillside embankment, rolling over several times before coming to rest approximately several hundred feet from the upper roadway in a foliage covered area. At the time of the collision, weather conditions were reported as being damp, and foggy with poor-limited visibility conditions. A short time later, First Responders summoned to the scene located the vehicle with two occupants nearby, who appeared to have been ejected from the automobile during the incident. An adolescent aged male was provided medical aid and emergently transported from the scene by paramedics to an area hospital for additional treatment. An adult aged male, reported to be the vehicle operator and the child’s father, succumbed to injuries he sustained in the collision; his death was pronounced on the scene without resuscitative aid provided.
The decedent has been positively identified as:
Trygve Walter HANSEN, a 53-year-old male from Inverness, CA.
A forensic post mortem examination and toxicology testing have been scheduled for early next week. The cause and manner of death will be pending the conclusion of the investigation being completed by the California Highway Patrol-Marin Office, California State Parks, and the Marin County Sheriff’s Office-Coroner Division. No further information will be released by the Coroner Division at this time, as this is an active and ongoing investigation. Any further questions regarding the incident should be directed to the California Highway Patrol-Marin Office, and California State Parks.
The Marin County Sheriff’s Office and personnel of the Coroner Division offers our best wishes and condolences to the family and friends of Mr. Hansen.
