 Mamaronek officials say they're planning to focus on improving pedestrian safety after a tragedy that killed a six-year-old boy and his mother. It was last month that the victims were struck and killed by a school bus that was turning while they were crossing the street at the corner of Mamaronek Avenue and New Street. An online petition has been launched in hopes of triggering changes that could save lives in the future. Westchester County and village leaders are set to talk next week. No charges were filed in connection with the tragedy.
