Among them was Larry Dwayne Hall, who authorities have long suspected may be responsible for kidnapping and murdering more than 50 women in the '80s and early '90s. Was Tammy one of them?

Is Serial Killer Larry Hall Connected to Tammy’s Murder?

It’s the dead of summer, 1989, in the heart of the Ozarks. An 18-year-old woman goes missing from Bella Vista, Arkansas. As the search moves forward, several suspects emerge. Then… a body is found not far from the Missouri border, and a homicide investigation begins. Soon, a second body is discovered nearby. What was a mystery transforms into the hunt for a possible serial killer stalking young women throughout the Ozarks. M. William Phelps digs in nearly 35 years later and begins to understand that things aren’t always what they seem. 

True crime

In this final episode of season 4, Phelps interviews a suspected serial killer, who he believes could be responsible for Dana Stidham’s murder—the first time anyone has spoken to the suspect about the case in 33 years.  After confronting him with the evidence, Phelps implores law enforcement to knock on the suspect’s door and interview him. A final call is made about the connection between the two murders - and who, ultimately, is to blame.  See omnystudio.com/listener for privacy information.

Meanwhile, Phelps continues to make connections to his new suspect. Phelps uncovers an old tape of a revealing interview with the man’s ex-wife.

Episode 7: “Killer Confrontation”

The second female victim, known only as “Grace Doe” for nearly 30 years, is identified as Shauna Garber. Phelps’s investigation turns toward a new suspect in the murder of Dana Stidham (and possibly Shauna), while uncovering a revealing, lost recording of a new suspect - unheard until now. Phelps teams up with the detectives investigating the Shauna Garber case, evaluating similarities between her and Dana Stidham’s death. All of it leads Phelps to the doorstep of a potential killer walking the streets a free man, confronting the man some think is a prolific serial killer who has eluded law enforcement for some 34 years.

Episode 6: “Spawn of Hell”

With the discovery of a second young female murder victim just over the Missouri border, 20 minutes away from where Dana Stidham’s body was found, a new suspect seems to be playing cat-and-mouse with law enforcement. Phelps drills down and compares the similarities in the cases—as infamous serial killer Dennis “BTK” Rader enters the narrative as a major suspect in both homicides.

Just over the Missouri border, not far from the Dana Stidham crime scene, a second young woman’s body is discovered. Are the cases linked? Phelps uncovers several exclusive, recorded interviews never-before-heard, speaks to several sources who claim that not only are the cases the work of one killer, but the suspect has been hiding in plain sight, taunting police, all along.
