The Genetic Detective

The killer of 8-year-old April Tinsley taunted police for decades in Fort Wayne, Indiana, leaving notes and threats with viable DNA samples, but they still couldn't catch him until now. Interviews featured in the episode include April's mother, Janet Tinsley, and cousin Kristina Snyder; Fort Wayne Police Department's Detective Brian Martin and retired detective Danny Jackson; coroner Chris Meihls; retired forensic scientist Linda McDonald; reporter Jamie Duffy; and Parabon NanoLabs' founder Steve Armentrout and director of bioinformatics Ellen Greytak. 

From 2006 to 2008, a series of unsolved rapes haunted residents in Fayetteville, North Carolina. Investigative genetic genealogist CeCe Moore works on the case with the Fayetteville Police Department while she attends CrimeCon, an annual true crime convention held in New Orleans. The episode includes interviews with survivor Kobi Haschen who bravely came forward with her story, Fayetteville Police Department's Lieutenant John Somerindyke and former supervisor Lieutenant Kellie Berg, sexual assault nurse examiner Liz Herring and reporter Paul Woolverton.

CeCe Moore gets an email from a St. George, Utah, detective asking her to work her first "hot" case, the rape of a 79-year-old woman that happened just three weeks prior. CeCe gets to work, knowing the rapist could easily strike again. Also: CeCe sees the first jury trial conviction from a case on which she worked, the suspect identified in the murder of Jay Cook and Tanya Van Cuylenborg from the series premiere.
