The CHP says a bicyclist who went down on Lucas Valley Road in Marin County on Saturday morning later died, though it may have been a medical emergency that caused him or her to crash in the first place.

Details of the 10 a.m. incident were not available, nor was the cyclist's name.

The individual was alone when the apparent crash occurred and was taken to a Kaiser medical facility, the CHP said.

The cyclist died after leaving the scene, the CHP said.
