Authorities ID Man Found Dead Near Wrecked Motorcycle In Petaluma

PETALUMA, CA — A man found dead Tuesday near a wrecked motorcycle in Petaluma has been identified by the Sonoma County coroner's office as Jason Roseveare, 40, of El Dorado. Caltrans workers who were cutting high grass Tuesday morning along Lakeville Highway found Roseveare's body near a drainage culvert around 8:40 a.m. near the South McDowell Extension, according to the Petaluma Police Department.

It appeared Roseveare was the victim of a solo-vehicle crash, but police have not received any information about when it happened, authorities said.

The discovery prompted authorities to close one lane of westbound Lakeville Highway at the S. McDowell extension for about three hours Tuesday.

The lane closure was lifted at about 12:15 p.m.

Based on a preliminary investigation by the Petaluma Police Department’s Traffic Unit and evidence found at the scene, police believe Roseveare's motorcycle left the roadway and struck a fence lining the roadway.

"While it does not appear that the motorcycle was involved in a collision with any other vehicles the cause of this collision is currently unknown," police officials said. "The collision appears to have occurred much earlier than the time of report, however, no reports regarding any collisions have been reported recently in that area."

Police are asking anyone who may have witnessed the motorcycle collision to contact Traffic Officer Pierre at 707-781-1208.
