A motorcyclist who died in North Fort Worth Monday has been identified as a teenager who got his high school diploma only 72 hours earlier. Austen Ussury was killed when he was thrown from his motorcyle on Keller Hicks Road, less than four miles from Keller High School where the 18-year-old had just finished his senior year. He received his diploma Friday night after completing a summer program that allowed him to meet graduation requirements.
