Justice delayed, lives destroyed: inside ‘The Murder of Rachel Nickell’ documentary

I watch a lot of true crime. Like many people, I am fascinated by the psychology, the investigations and the search for justice. But now and then, a documentary comes along that reminds you there are real people behind the headlines.

Netflix’s “The Murder of Rachel Nickell” is one of those documentaries.

The film revisits the murder of 23-year-old Rachel Nickell, who was attacked and killed on Wimbledon Common in London in 1992 while walking with her two-year-old son, Alex Hanscombe.

The case shocked Britain and became one of the country’s most infamous murder investigations. Nickell was stabbed 49 times, and her son was the only witness to the attack.

What stayed with me throughout the documentary was not the murder itself. It was Alex.

As a mother with a son of my own, I found it impossible not to put myself in that situation. Watching footage and hearing accounts of a little boy trying to make sense of something no child should ever witness hit me harder than any of the crime scene details ever could.

In many true crime documentaries, the victim can unintentionally become secondary to the investigation. Here, Nickell remains at the centre of the story. She is not reduced to a case file or a headline.

She is presented as a young mother whose life was stolen and whose family would spend decades living with the consequences.

The documentary also exposes the staggering failures that followed. Under immense public pressure, police became fixated on Colin Stagg and pursued a controversial undercover operation in an attempt to secure a confession.

He was later exonerated. Meanwhile, the real killer remained free for years.

And that is where the documentary becomes deeply frustrating.

You find yourself watching with your mouth hanging open, wondering how so many opportunities were missed. Knowing that the actual killer, Robert Napper, was only identified years later through advances in DNA technology makes the failures feel even more devastating.

What I appreciated most was the restraint. The streaming platform could easily have turned this into another sensational true crime story. Instead, director Lucy Bowden focuses on the people left behind.

The documentary gives space to Alex, André Hanscombe (Nickell’s partner) and even Stagg, whose life was permanently altered by the investigation. For me, those were some of the most powerful moments.

Alex was only two years old when he witnessed the murder of his mother, yet the effects of that day followed him for decades. Watching him speak about the trauma, the media attention, and the weight of growing up attached to one of Britain’s most notorious murder cases was heartbreaking. André’s story is equally moving.

Beyond losing his partner, he was left to raise a young son while navigating grief in the public eye. Then there is Stagg, a man whose reputation was destroyed after being wrongly targeted by police.

The documentary reminds viewers that when investigations go wrong, the damage extends far beyond the victim and can shape entire lives.

There were several moments where I had to pause and take a breath. Not because the documentary is graphic, but because it is emotional. Watching André try to protect his son while navigating unimaginable grief is incredibly moving. As a parent, those scenes landed differently.

More than anything, “The Murder of Rachel Nickell” is a reminder that justice delayed leaves damage far beyond a courtroom. It leaves families carrying wounds for decades.

It is heartbreaking, infuriating and incredibly human. And if you are a parent, do not be surprised if you find yourself hugging your child a little tighter afterwards.

Rating: **** a standout film with exceptional qualities.
