On Saturday April 09, 2022, at approximately 10:47 AM, a solo motorcycle collision was reported to have occurred on Point Reyes Petaluma Road, Chileno Valley in West Marin, which transitions into the 6500 block of Red Hill Road, Petaluma.  Reportedly the subject was travelling westbound on the roadway operating a motorcycle and experienced a mechanical defect.  Ultimately this caused him to lose control of the vehicle resulting in him being ejected from the motorcycle to the surrounding ground and vegetation.  The subject was located by witnesses unconscious and unresponsive in cardiopulmonary arrest. Bystander CPR and medical aid was provided until the arrival of first responders at the scene. Paramedics provided emergent advanced resuscitative aid on the scene, and regrettably the subject failed to respond to the treatment provided.  His death was pronounced on the scene.
