West Marin Motorcyclist Collision Fatality Identification Released

The decedent has been identified as:

Martin RODRIGUEZ-SIGNOR, 23-year-old resident of Petaluma, CA

On Monday, July 09, 2018 at approximately 3:33 PM, First Responders were dispatched to the 2600 block of Tomales-Petaluma Road near Twin Bridge Road in Chileno Valley for the report of a motor vehicle collision involving a motorcyclist and a sport utility vehicle.  First Responders arrived on the scene shortly after and discovered a male victim, unresponsive and unconscious.  Preliminary investigation completed suggests the subject was operating his newly purchased 2019 Triumph Speed Triple sport motorcycle eastbound on rural Tomales-Petaluma Road, at a high rate of speed and for reasons unknown at this time, crossed over the double yellow painted road dividing lines, and struck a westbound Toyota Highlander sport utility vehicle head on.  The subject was ejected from his motorcycle and came to rest on the roadway shoulder.   Unfortunately as a result of the collision, the subject suffered extensive traumatic injuries and his death was pronounced on the scene by paramedics. 

The decedent has been identified as:

Martin RODRIGUEZ-SIGNOR, 23-year-old resident of Petaluma, CA

A forensic post mortem examination and toxicology testing have been scheduled for later this week.  The cause and manner of death will be pending toxicology results and the conclusion of the investigation by California Highway Patrol, Sonoma Office.  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, Sonoma Office.

The Marin County Sheriff’s Office and personnel of the Coroner Division offers our condolences to the family and friends of Mr. Rodriguez-Signor.
