Emmy Award-winning journalist Chris Hansen returns to America’s leading true-crime network Investigation Discovery (ID) for the third season of KILLER INSTINCT WITH CHRIS HANSEN. With a proven track record for gaining access to hard-to-get interviews, Hansen sets himself apart as a journalist for his ability to both empathize with those closest to the case and analyze his findings objectively for the sake of the investigation. To gain this perspective, Hansen visits each distinct crime scene location to look back on some of America’s most unnerving homicides and the lives that were shaken in an all-new season of KILLER INSTINCT WITH CHRIS HANSEN premiering Tuesday, September 5 at 9/8c on ID

This season, Hansen finds himself exploring a number of cases dating back to the 1990s. Even decades later, Hansen never strays from retaining the raw emotions felt and the facts obtained from the very beginning. The season premiere of KILLER INSTINCT features the 1993 murder of Tammy Tatum, who was found dead in her Colorado home with her baby, Sadie, asleep in her crib. The killer was identified 13 years later. Now, 24-year-old Sadie recounts to Hansen what is was like growing up and coming to terms of her mother’s passing. As Hansen reinvestigates Tammy’s death, lead law enforcement official, Detective Bruce Vaughan, shares details of the puzzling case that kept him awake at night for 13 years, “Having the knowledge that the baby was [at the crime scene] was disturbing being a parent myself,” he recalled.
