The CHP is searching for a 21-year-old Santa Rosa man suspected of fleeing after a crash that injured his passenger late Tuesday night.

Skylar Storm Sachse, whom CHP described as a known gang member, fled on foot after crashing a Dodge Neon sedan into two sections of guardrail on River Road east of Oddfellows Park Road near Guerneville around 11:25 p.m., according to a news release. His 17-year-old female passenger sustained moderate injuries in the crash and was taken to a nearby hospital.

It is unknown why Sachse lost control of the car, though CHP said alcohol is suspected in the crash. Sachse was on felony probation stemming from prior weapons violations, CHP said.

Anyone with information about the crash or Sachse should call CHP at 707-588-1400.
