It was an emotional hearing as a 29-year-old Morris County man who admitted to killing a pedestrian with his pickup truck was sentenced to probation after a year in county jail. In May, Matthew Vining, of Chatham Township, pleaded guilty to third-degree vehicular homicide, and a traffic violation for failure to maintain a lane in the deadly winter crash in Chatham Borough. Family and friends of the victim, Patricia Smith Barrett, filled the courtroom on Thursday.
