An Arroyo Grande woman is facing murder charges for her involvement in a deadly DUI crash last December. Prosecutors have charged 26-year-old Chelsea Stiles with murder in the death of Terry Tilton who died as a result of the crash. Investigators believe she intentionally caused the crash on Highway 227 following a visitation with her daughter’s biological father. The 18-month-old girl was not injured in the crash. If she’s found guilty, Stiles could face life in prison. She’s due back in court next month.
