A Wilton High School student was gravely injured Friday and hospitalized, according to a letter from the Superintendent to the school community.  Kevin Smith wrote that he was unable to share additional details at this time but believe that many high school students and families may already be aware of the event and are naturally extremely upset.  Police responded to the woods off Pin Oak Lane Friday night on a report of a 15-year old who was in distress and possibly suicidal.  Police located the injured teen and transported him to the hospital.  School officials provided the 24-hour hotline number for Kids in Crisis, 203-661-1911. Counselors were available throughout the weekend.
