Reporter Justin Glanville, whose parents personally knew one of the victims, is investigating the brutal 1970 murders of Mary Petry and Bill Sproat. The crime was so brutal, in fact, that it drew comparisons to the Manson murders of the previous year. In his investigative podcast, "Mary & Bill: An Ohio Cold Case," Justin works with his family, sisters of the victims, and Columbus police to try and finally find out what happened to the scholarly couple back in 1970.
