A 39-year-old Long Beach man was charged Friday with murder in the killing of a bicyclist in Dana Point.
Vanroy Evan Smith also faces a sentencing enhancement for the personal use of a deadly weapon.
Smith is accused of killing Dr. Michael John Mammone, 58, about 3 p.m. Wednesday at Pacific Coast Highway and Crown Valley Parkway.
Orange County sheriff’s deputies were dispatched to the corner for a traffic collision and assault.
The victim was riding a bicycle north on PCH when Smith struck him from behind and then got out and stabbed the bicyclist, sheriff’s deputies alleged. Bystanders detained Smith until deputies arrived.
Sheriff’s investigators say there does not appear to be any connection between the two.
Smith could face up to 26 years to life in prison if convicted at trial.
