Kindergarten student Avery Green surprised his teacher, Keri Stromski, with a "hugging machine" he and his mother made for her. Stromski, who had stage-four breast cancer when she spoke in March about the creation with Newsday's Cecilia Dowd, died Tuesday, according to a spokesman for the Riverhead Central School District.
