Welcome to SIC PART TWO

Just one year after terrorizing a family from inside their walls, Daniel LaPlante’s crimes escalated to something even more horrifying. In December 1987, in the small town of Townsend, Massachusetts, a husband returned home to find the most horrific scene. The investigation revealed a trail of stolen guns, matching bullets, and chilling evidence — all leading back to the boy once mistaken for a ghost. This half of the story unravels the brutal murders of the Gustafson family and the trial that finally put Daniel LaPlante behind bars.

Welcome to SIC, PART ONE:

It began with whispers in the night, noises no one could place. A family grieving their mother thought it might be her, reaching across the veil. But as days passed, the whispers became knocks, the knocks became footsteps, and the fear in their home turned suffocating. Whatever was in their walls, it was alive.

In 1974, nineteen-year-old Patricia Hearst was ripped from her apartment at gunpoint. Within days, a radical group calling themselves the Symbionese Liberation Army claimed her as their prisoner and issued a ransom demand unlike anything America had ever seen. But when Patty finally resurfaced, she wasn’t begging for freedom. She was carrying a rifle.

Welcome back to SIC!

Today we cover one of the most confusing missing persons cases from the early 2000's.

In February 2004, 21-year-old nursing student Maura Murray vanished after a car crash on a dark New Hampshire road. Within minutes, she was gone — leaving behind a locked car, spilled wine, and a trail of confusing leads. Was she running away, the victim of foul play, or caught in something stranger? In this episode, we unravel the final days of Maura’s life, the conflicting witness accounts, and the haunting theories that still leave more questions than answers.

The murder of Hae Min Lee, and the conviction of her ex-boyfriend Adnan Syed, has become one of the most debated true crime cases of our time. With resurfacing witnesses, changing stories, and DNA evidence revealed, the question remains unsolved: is Adnan Syed guilty? If Adnan didn’t kill Hae, then who did?

From the original evidence to the most current updates, this episode offers a surface-level rundown of the case that launched modern true crime podcasting.

Welcome back to another episode of SIC!

This weeks case started as a quick trip to see a used car. Somewhere between the parking lot and the open road, 18-year-old Zebb Quinn took an unexpected detour — and was never seen again. Four days later, his car surfaced under eerie circumstances: headlights still glowing, a puppy in the seat, and lipstick markings on the back window. The clues are strange, the connections even stranger, and every possible lead seems to raise more questions than it answers.

Listen now for all the clues, theories and confessions.

What happens when the justice system isn’t fast—or harsh—enough for a grieving parent? In this episode of Siblings in Crime, we dive into two true stories of vigilante justice that shocked the world. First, we follow the case of Gary Plauché, the Louisiana father who calmly waited at an airport with a revolver in his boot—then shot his son’s abuser on live television.

Then, we cross the ocean to West Germany, where Marianne Bachmeier walked into a courtroom and gunned down the man who murdered her 7-year-old daughter. Both parents took the law into their own hands. Both were arrested.

And both were asked the same question: Was it justice… or just revenge?
