Show Notes
Mackenzie Cowell was seventeen years old — a dancer, a cosmetology student, and a young woman with her whole life mapped out in front of her — when she stepped out of her beauty school in Wenatchee, Washington one February afternoon and never came back. Four days later, her body was found partially submerged in the Columbia River, twenty miles from where she had disappeared.
What followed was one of the stranger murder investigations in recent Washington state history. Investigators chased a months-long dead end involving drug dealers, a supposed snuff film, and an informant whose story kept changing. Meanwhile, the real answer had been hiding in plain sight — in the classroom where Mackenzie spent her afternoons, and in an apartment where a piece of carpet held a secret that luminol would eventually reveal.
Mackenzie had survived a difficult childhood, a contentious home life, and the relentless schedule she had set for herself. She made it through all of that. She didn't make it through one ordinary Tuesday afternoon.

In January 1897, a young bride, Zona Shue, was found dead on the floor of her home in the mountains of West Virginia. The doctor called it an everlasting faint — an old fashioned term for a sudden, unexplained death from natural causes. Days later, Zona’s mother woke in the cold, dark night to find an apparition standing at the foot of the bed. It was Zona, back to tell the story of how she really died. But would a jury buy it?
On paper, they looked like the perfect couple — a Harvard-educated law professor and a passionate immigration attorney, both brilliant, driven, and devoted to their two little boys. But behind closed doors, their differences were driving them apart. Throw in a mother-in-law who needed to control everything, and a protective older brother with a tough-guy image, and it was a recipe for things to get very ugly. Eventually, it would end with murder. But would there ever be justice?

In August 1995, Mark Winger called 911 from his Springfield, Illinois home. His wife, Donnah, had been brutally attacked by an intruder brandishing a hammer. Mark intervened, shooting the man dead. Police ruled the shooting a justifiable homicide. The case was closed, and Mark was labeled a hero. There was little reason to question what had happened inside that house. But years later, the thoroughness and credibility of that investigation would be called into question.
