The reward is being increased to $10,000 for information that leads to an arrest in the death of a Central Michigan University freshman last year.
Crime Stoppers of Flint and Genesee County said Monday that the increase comes at the Tuesday one-year anniversary of 17-year-old Ryan Tsatsos' death. He was struck and killed by a hit-and-run driver near the school's Mount Pleasant campus on Nov. 1, 2015.
Three new billboards are advertising the increased reward. Crime Stoppers is offering $2,500 and Tsatsos' family is offering $7,500.
Police say Tsatsos pushed another person to safety before being struck. He was walking with friends back to his residence hall when he was hit. The student from the Detroit suburb of Macomb Township was pronounced dead at the scene.
