54-year-old Jean Heppler was killed while crossing a street in a Dedham traffic crash on Friday night. Heppler was struck by a vehicle driven by a Mount Ida College student. The driver, Nicolas A. Rivas-Vasquez, pleaded not guilty to leaving the scene of the catastrophic pedestrian accident.
The 21-year-old’s lawyer said that Rivas-Vasquez did not know that his car had hit Heppler. Instead, the college student thought that his vehicle was struck by an object that the wind had blown in.
Although Rivas-Vasquez stopped the car, he claims that didn’t see anything in the mirror. Because of the road he was on, he had to drive another few blocks before he could legally turn back. Even then, Rivas-Vasquez contends he only saw debris. He later turned himself into the authorities.
