A well-known Mendocino County psychiatrist was struck and killed by a big rig Friday morning while riding his bicycle near downtown Ukiah.
Douglas Rosoff, 56, of Ukiah, was an avid cyclist known for his regular morning, pre-work rides.
He also was a respected figure in Mendocino County government, where he was the chief psychiatrist in the county's mental health division until a 2011 move to work for the Veterans Administration.
He died shortly before 8 a.m. on his regular East Gobbi Street route, apparently as he and the trucker approached the South Orchard Street intersection.
Preliminary investigation indicated the westbound trucker turned right from East Gobbi onto northbound South Orchard, colliding with Rosoff, who also was westbound, CHP personnel said.
Ukiah Police Capt. Justin Wyatt, whose agency is leading the investigation, declined to release further details or the name of the truck driver. Wyatt did not clarify whether the driver saw Rosoff in advance of the crash or not.
A female companion traveling behind Rosoff was unhurt, Wyatt said, though witnesses described her as distraught.
The 7:57 a.m. collision and its aftermath were highly visible to commute-hour traffic along the busy road.
Among those stopped in traffic immediately afterward was Tim Walsh, owner of Ukiah Schwinn/Ukiah Bike Center a few blocks down East Gobbi Street from the accident site.
"I'm just devastated," Walsh said, describing Rosoff as "a heck of a nice guy."
