SANTA ROSA (KRON)–A bicyclist suffered life-threatening injuries in a collision with a vehicle Tuesday evening in Santa Rosa, police said.

At 7:20 p.m., officers were dispatched to the intersection of Stony Point Road and Sebastopol Road for a collision involving a vehicle and a bicycle.

Natal’s vehicle. Tinoco hit the vehicle’s windshield and fell to the ground, police said.
