Updated: Sonoma Woman Killed in July 4 Vehicle Crash

The California Highway Patrol is investigating the crash that took an 81-year-old Sonoma woman's life on July 4.

The crash was reported at 9:52 a.m. on Leveroni Road at Fifth Street West.

Witnesses watched as Carolyn Dusharme drove her 2001 Mitsubishi Galant through several intersections along Fifth Street West, finally colliding into a metal guard rail on Leveroni Road.

The car flew past the barricade, towards Sonoma Creek, crashing into the creek's southern embankment, said CHP officer Jaret Paulson. Emergency crews found Dursharme dead on arrival.

Witnesses said Dursharme was driving without regard to traffic, running several intersections; but the CHP does not believe alcohol or medication were involved, said Paulson.
