Special 145: Swans Don't Swim in a Sewer: Solving the Cold Case of the Flint River Serial Killer's Daughter by Sheryl 'Mac' McCollum

Sheryl "Mac" McCollum, host of the podcast Zone 7 and gifted CSI, is back on the Murder Shelf Book Club podcast to discuss her new true crime book, Swans Don't Swim in the Sewer! The death of a child is devastating for any parent, family, and loved ones. However, when the child is the daughter of a serial killer who asks for help in solving her murder, it takes the investigation to an entirely new level—something that has never happened before. And the professionals who gave their time and expertise in pursuit of justice will astound you. Sheryl also updates Jill on new developments at Wildlife CSI and on training options for both law enforcement and civilians in 2026.
