A teenager who was killed when his pickup truck veered off the road and was submerged into a pond was honored at his high school this week. Friends of 17-year-old Wyatt Carleton are remembering him as “a ray of sunshine”. Groups of students, teachers and community members gathered at Merrimack Valley High School in memory of the senior. Carleton was killed early Monday in Andover when his pickup truck skidded off the road into a fire pond.
