In March 2021, a single seemingly normal journey, was about to take a terrifying turn. What began as a simple walk home would spark nationwide outrage, shatter a sense of public safety, and cause debates still ongoing to this day.

Today, we retrace the final movements, and ultimately the tragic death, of a young woman whose name would become known across the world.. for all the wrong reasons.

There are some cases that refuse to stay buried— Scott Peterson had his death sentence overturned and has stated 'new evidence' has come to light.

Does this change anything with his murder conviction? Is an innocent man behind bars? Or are we still certain he killed his wife Laci Peterson and their unborn son?

Scott Peterson wasn’t about to go quietly. The question is, what is this new evidence? Does everything we thought we knew still hold up when it’s examined again under a harsher light?

At first, nothing about Christina Harris’s death made sense. Something about the way she was found just felt unexplained.

But sometimes the truth in a case like this doesn’t arrive in a confession or a courtroom revelation. Sometimes, it’s something far smaller.. something overlooked.. something sitting quietly in the most ordinary place in the house - the fridge.

The apartment was locked. Outside, snow was falling across Philadelphia. Inside, 27-year-old Ellen Greenberg lay dead on her kitchen floor.

She had 20 stab wounds to her body. What happened next would spark a debate that has lasted more than a decade. Investigators changed their conclusions, forensic experts disagreed, and Ellen's parents began a relentless fight to uncover the truth.

What really happened to Ellen Greenberg? Was this a tragic suicide, or does one of America's most baffling death investigations still have crucial questions left unanswered?

A hundred miles an hour. No skid marks. No attempt to brake.

In the early hours of a summer morning in Strongsville, Ohio, a car carrying three young people slammed into a brick building with devastating force.

At first, people assumed it was a tragic accident. But as investigators dug deeper into the wreckage, examined phone records, and uncovered the turbulent relationship at the middle of the case, a far darker picture began to emerge.

was this a catastrophic mistake... or cold blooded murder?

She was 19 years old, ambitious, bright, and stepping into what should have been the beginning of her life. But after a first date on a spring evening in Milwaukee, Sade Robinson vanished without a trace.

She left behind a trail of disturbing clues that would unravel into one of the most horrifying murder investigations the city had seen in years..

On a warm Sunday morning in rural Ballarat, a mum of three laced up her running shoes, and stepped outside for what should have been a normal run. And then vanished without a trace.

She knew the bushland like the back of her hand. So how the hell did she fall off the face of the earth?

The trail abruptly ended, and the mystery gripped Australia. This is the chilling case of Samantha Murphy.

In Apple Valley in 2010, 4 people suddenly disappeared off the face of the earth. This kind of thing was unheard of in this small community.

And when police discovered a house soaked in blood, time started ticking.

A race against the clock.. track down the man responsible, and find the victims.. alive.. or dead.
