A 61-year-old Petaluma woman was killed Friday when a speeding car ran off Bohemian Highway north of Camp Meeker, plowed into a gazebo where she and a half-dozen people were standing and launched over a creek at a conference center.
The driver and her passenger were hospitalized, but no others were injured in the freak crash, at 1:25 p.m. at the Alliance Redwood Conference Grounds.
“It could have been a lot worse,” said CHP Sgt. Bob Barr.
The woman killed wasn't identified pending notification of her family. She was with her husband and at least one friend waiting to go on a popular zipline “canopy tour” through the redwoods, authorities said.
It was unclear why the driver, Johnella Thomas, 74, of San Francisco, suddenly veered off northbound Bohemian Highway, a curvy road where signs warn “slippery when wet” and potentially icy conditions. Conditions were clear and dry Friday.
Barr said a driver behind Thomas about a half-mile before the wreck saw her 2010 Mercedes C300 traveling at 25 mph to 30 mph, near the posted speed limit.
The witness said Thomas suddenly accelerated and pulled away, going so fast she could barely stay on the road.
He estimated the Mercedes' speed at 70 mph.
“He lost sight of the car, then came around the corner and saw dust and carnage,” Barr said.
The victim was standing near an open redwood platform covered by a pop-up gazebo, where customers of the canopy tours gather before being escorted to another section of the conference center to visit the redwoods, said Jim Blake, the center's executive director.
Mary Krieger, 63, of Indiana and Ginger Bird, 46, of Vacaville were among those standing nearby; the others weren't identified.
They were not seriously injured, although some people in the group may have been struck by flying debris.
Barr said the CHP hadn't ruled out any causes — mechanical, health problems for the driver or drugs or alcohol use, although he said there wasn't any indication of those substances at the scene.
