The Monster on Giglo Beach: The Rex Heuermann Case

Mark Twitchell was an aspiring filmmaker with a successful cult film, a wife and a young child. But he harbored a dark secret, the inexplicable desire to become a serial killer, partly inspired by the fictional character Dexter from the eponymous show. This week, Savannah explores how Mark was able to catfish two unsuspecting men from dating sites into his makeshift "kill room," which ultimately led to him murdering Johnny Altinger on October 10, 2008. Savannah also explores the many manifestos he wrote that make it clear that, had investigators not caught him, he would've certainly killed again. Love Killer Instincts but hate the ads?

What began as a simple home renovation project in San Marino, CA, ended in an arrest for murder. When Johnathan Sohus' body was uncovered in the backyard of the home, investigators were able to finally pin the killing on long-time con artist Christian Gerhartsreiter AKA Clark Rockafeller, Christopher Chichester, and many other aliases. But one mystery still remains, what ever happened to John's wife Linda Sohus, who is still considered missing? This week, Savannah explores the couple's tragic story that begins in 1985 and still open-ended. Savannah details the postcards supposedly sent from the couple while they were missing that were likely sent from their killer, how Christian was able to con hundreds of people, and how he was ultimately captured.

The story of Amber Smith's attack is a story of survival, but her ordeal was still horrifying. This week, Savannah details how Amber was bound, beaten and left for dead at Cottonwood Glen Park, a park near where she lived.

Katherine Waring seemingly vanished out of thin air on June 12, 2009. When an uncharacteristically large-sum check surfaced, having been signed by Katherine (who went by Kate), it started a chain of events that ultimately lead to the horrifying truth, Kate was brutally tased, beaten and drowned by people that she trusted. This week, Savannah details the many players in Kate's disappearance and killing, including Ethan Mack, someone who was like a brother to her that convinced Kate to get into the suitcase that was used to kill her, Heather Kamp, the con artist who plotted her murder in order to steal her money and belongings, and the A-team, the group of experts that did what the police had failed to do for months, solve the case and find Kate's killers.

This case actually involves several cases of accidental death and murder. Savannah explores the legacy of the famous (and often infamous) Murdaugh family and the many tragedies that have surrounded them. Savannah starts with the most recent incident on June 7, 2021 where Maggie and her son Paul Murdaugh were found shot to death near their hunting lodge in South Carolina, and backtracks to a boat accident that killed teenager Mallory Beach, and that many believe let Andrew Murdaugh off the hook for his reckless behavior. She also details the still-unsolved murder of Stephen Smith, where many residents are convinced that Andrew Murdaugh may be directly responsible. So were Maggie and Paul's murders a random act of violence or was this an act of revenge for the family's checkered past? Love Killer Instincts but hate the ads?
