It seemed like life in the small town of Selmer, Tennessee, revolved around the well-known and beloved church pastor Matthew Winkler. Matthew, along with his wife Mary and their three daughters, were seen as a perfect family — until parishioners discovered their pastor's body in the family's home, and Mary and the daughters were nowhere to be found.

When Tricia Todd, a young mother who recently relocated to Hobe Sound, Florida, failed to pick up her 2-year-old daughter from the babysitter, her family was instantly worried. Police conducted an extensive search, questioning a pastor who twice met Tricia during her evening walks on the beach, a local ventriloquist whom she was infatuated with, and her ex-husband Steven Williams. But when those leads seemed to go nowhere, authorities were left wondering— who would want a young mother dead?

The last time anyone heard from Tracie Hawlett and J.B. Beasley, two teenagers on the verge of their senior year in high school, was on a sweltering July night in 1999. Tracie called her mother from a payphone to say they were on the way home from celebrating J.B.'s birthday — but the two never made it home. The girls' bodies were discovered in the trunk of J.B.'s car, less than a mile from the payphone, with gunshot wounds to their heads. Despite exhaustive efforts, including attempts to identify unknown male DNA found on one of the girls, the involvement of multiple agencies, national TV appeals, and even attempts at hypnosis of eyewitnesses, the case eventually went cold. In 2019, the use of genetic genealogy led to a breakthrough, resulting in a shocking arrest. Could they have finally found the killer?

In 2016, Fabio "Big Daddy" Sementilli was a beloved and sought-after hairstylist with a client roster that included Jennifer Lopez, Russell Crowe, Jackie Chan, Jennifer Love Hewitt and more. When Sementilli was discovered lying lifeless on his family's pool deck with multiple stab wounds to his neck and back, his family, friends and the hair-care industry were devastated. Initially, police suspected he had been a victim of a burglary gone wrong — until DNA found in his car led them to an unlikely suspect, who had attended Sementelli's memorial service sporting an injury.

In 2011, a witness last saw 20-year-old nursing student Holly Bobo walking into the Tennessee woods with an unknown man. Three years later, authorities found her remains miles from her home. After the largest and most expensive investigation in the Tennessee Bureau of Investigation's (TBI) history, authorities ultimately charged Zach Adams, Dylan Adams and Jason Autry with the kidnapping and murder of Holly. Although there was little physical evidence and no DNA linking any of the men to the crime, a jury convicted Zach at trial — based mainly on Jason's testimony, in which he stated that he had been present when Zach shot and killed Holly. Dylan Adams and Jason Autry both eventually pleaded guilty to lesser charges. Earlier this year, Jason recanted his testimony, saying he made it all up, and while prosecutors stand by the conviction, lawyers for Zach are now asking a judge to grant him a new trial.
