Behind Closed Doors

Six members of one family were found murdered inside their quiet Carnation, Washington home, including two young children. What happened behind those closed doors was so brutal that the truth would take years to fully come to light.

Nine children. Thirteen years. One mother.

Marybeth Tinning watched child after child die—until investigators began asking the question no one wanted to ask:

What if she was the reason?

In 1983, Diane Downs arrived at an Oregon hospital with her three children suffering from gunshot wounds. She claimed a mysterious stranger had attacked them on a deserted road—but investigators quickly began questioning her story. One child died, two survived, and a trail of evidence would eventually lead police to a shocking conclusion.

The Lindsay Clancy trial is nearing its end, but the questions surrounding her mental state only seem to get bigger. In Part 3, we dive into the latest testimony, the disputed voice, and the competing theories about what happened that night. What really happened behind closed doors?

Join us for the continuation of the Lindsay Clancy trial. Which side is the truth?

No verdict. No resolution. Just fifty-four minutes that changed everything. This is the chilling, still-unfinished story of Lindsay Clancy.

For nine days, a small town prayed for two missing boys while the truth sat somewhere much closer than anyone imagined. This week, we ask how a mother becomes the last person anyone suspects, and what finally made the story fall apart.

Ever wonder why our cases don't all fit the same mold? This week we step back from a single story to break down the research behind why parents kill their children — and why one theory alone was never going to explain all of it.

She was the mother everyone else measured themselves against. She was gentle, devoted, and endlessly patient. On a quiet morning in June 2001, she drowned all five of her children in the bathtub, one by one. What was happening inside her mind may be even harder to sit with than what happened in that house.

Content warning: child death, suicide, and severe mental illness.

A farmhouse. A family. Poison. A deadly mixture of despair and desperation.
