Family and friends of 16-year-old Dalton Kuhn light and release purple lanterns into the sky on Tuesday, October 10, 2017, while gathered on the side of State Road 312 on the one-year anniversary of his death. Purple was the teenager’s favorite color. Investigators with the St. Augustine Police Department believe that Kuhn was hit and killed by a white Chevy 2500 diesel pickup truck between the model years 2003 and 2006, while walking or skateboarding alongside the road. The driver did not stop and has not come forward. Anyone with information about the case is asked to call Detective Sergeant Jason Etheredge at 825-1092. Those who wish to remain anonymous can call Crime Stoppers of Northeast Florida at 888-277-8477. (Christina Kelso/ The St. Augustine Record)
