True Crime Creepers

When Peggy Carr suddenly became violently ill in October 1988, doctors were baffled. She complained of excruciating pain in her feet, began losing weight at an alarming rate, and eventually slipped into a coma. Then other members of her family started showing the same mysterious symptoms.

As panic spread through their small Florida community, investigators discovered the family had been exposed to a rare and highly toxic poison. But how had it gotten into their home? And more importantly, who would want to target an entire family?

What followed was a years-long investigation involving FBI profilers, a brilliant and eccentric suspect, and one of the most unusual undercover operations we've ever covered. This is the story of Peggy Carr, a poisoning that shocked Florida, and the hunt for a killer who believed he'd committed the perfect crime.

In February 2005, Danielle Imbo and Richard Petrone Jr. left a bar on Philadelphia’s South Street after a fun night out with friends — and were never seen again. Even more bizarre? Richard’s massive black Dodge Dakota truck vanished with them, without leaving behind a single trace.

What began as a missing persons case quickly spiraled into one of Philadelphia’s most baffling mysteries. Investigators uncovered a contentious divorce, threatening phone calls, rumors of organized crime involvement, and a possible murder-for-hire plot tied to Philly chop shops and the criminal underworld. But despite years of investigation by local police and the FBI, no arrests have ever been made and no evidence has ever definitively revealed what happened that night.

This week, we’re heading deep into the Alaskan wilderness to cover one of the most chilling mass murders in the state’s history — the 1983 McCarthy massacre.

McCarthy wasn’t just remote… it was practically off the grid entirely. A tiny community tucked inside Wrangell-St. Elias National Park where residents crossed icy rivers by hand-powered tram, recognized each other by boot prints in the snow, and gathered every Tuesday for the biggest event of the week: mail day.

But on March 1st, 1983, that quiet tradition turned into absolute horror.

A man named Louis Hastings arrived with a rifle, a plan, and a terrifying mission that would leave six people dead, two more wounded, and an entire community permanently shattered. And somehow, the motive behind it all is even more unbelievable than the crime itself.

This case has isolation, survival stories, a real-life sniper hunt in the snow, and one of the strangest murder plots we’ve ever covered.

Jason Young was three hours away when his wife was murdered. Receipts, surveillance footage, phone records—on paper, everything checks out. He was exactly where he said he was.

But the more investigators dig in, the more that story starts to fall apart.

There’s a gap in the timeline no one can fully explain. A security camera that was tampered with. A strange stop at a gas station that raises more questions than answers. And piece by piece, it starts to look less like coincidence… and more like something planned.

As more comes to light—affairs, money, a marriage that was clearly struggling—the question becomes harder and harder to ignore:

Was this a solid alibi… or something much more calculated?Sources:

A routine favor turns into a nightmare.

When Meredith Fisher agrees to stop by her sister’s house, something feels off the moment she arrives—lights on in the middle of the day, a dog whining inside, a door that won’t open. What she finds upstairs will haunt her forever: a brutal crime scene, her sister dead, and a child left behind in the aftermath.

As investigators begin to piece together what happened inside that house on Birchleaf Drive, the picture that emerges is anything but simple. A marriage unraveling. Fights escalating. Secrets building.

And a husband who just happens to be out of town… with a story that almost makes sense.
