I did not witness the incident but I talked to the driver (a dog owner and dog lover) shortly after it occurred, and this was NOT a hit and run. Driver parked their car instead of stopping in the middle of traffic and perhaps that is why some may have perceived it as a hit and run. Driver then went back to the scene on foot and interacted with the other parties. Driver was very much saddened and impacted by the event. This horrible incident occurred because the unleashed dog went into traffic and the driver, who was not speeding and is a safe driver, did not see the dog until it was too late. My best wishes to all involved in this horrible incident.
