A cyclist named Sheri Mann was killed a few months ago while riding her road bike in Redding, CA. Mrs. Mann was a well known and avid bicyclist in the area. The young mother who struck her was not prosecuted though. She struck Mrs. Mann while reaching into the back seat of her car for a baby bottle.
Redding District Attorney published an open letter in The Redding Record Searchlight, explaining why he made the decision he did to not prosecute the driver of the car. Here is the link:
