Police in a southern Ontario municipality say they have solved the murder of a 16-year-old girl that took place more than 50 years ago. York Regional Police say Yvonne Leroux was last seen walking in a Toronto neighbourhood one night in November 1972 and a passerby discovered her body in the Township of King, about 24 kilometres north of the city, the next morning.A York Regional Police patch is shown Dec, 19, 2022 in Aurora, Ont.
