William Guerne was westbound on River Road near Slusser Road at about 6:45 p.m. Tuesday, September 5th, 2017 when his 2003 Dodge 2500 pickup crossed the double-yellow lines and sideswiped an oncoming Peterbilt dump truck driven by Juan Salasrangel, 63, of Santa Rosa.
Guerne veered left across oncoming traffic, crashed through a metal guardrail and hit a tree.
Guerne was pronounced dead at the scene.
Salasrangel wasn’t injured.
The CHP is currently investigating whether a medical condition caused Guerne to veer into the oncoming lane.
