The Confession That May Never Be Solved
In 2014, a struggling New Zealand builder named David Lyttle sat across from a powerful crime boss and admitted to murder.
He described shooting his best friend, Brett Hall. He explained how he disposed of the body. He even led investigators to places where he claimed body parts were buried.
There was just one problem.
Police found nothing.
No body. No remains. No murder weapon. No physical evidence connecting Lyttle to the killing.
Yet that confession would become one of the most controversial pieces of evidence in modern New Zealand criminal history.
A Friend Vanishes
Brett Hall disappeared from his remote Whanganui campsite in May 2011. The 47-year-old was never seen again.
Hall and Lyttle were close friends. Lyttle had been helping build a house on Hall’s property, and investigators quickly focused on him as a person of interest.
But years passed without enough evidence to charge anyone.
Then police turned to a controversial investigative tactic known as a “Mr Big” operation.
Enter Mr Big
The strategy is simple in theory and unsettling in practice.
Undercover officers create a fake criminal organisation and slowly recruit a suspect into it. They offer friendship, money, status and belonging. Eventually, the suspect is introduced to the boss — “Mr Big” — who demands complete honesty about any past crimes.
Only a handful of countries permit the tactic.
For David Lyttle, the operation lasted months. He was driven around in luxury vehicles, introduced to people he believed were serious criminals and given opportunities that appeared to promise a better life.
When he finally met the boss, he confessed.
According to the undercover recordings, Lyttle described shooting Hall, dismembering the body and burying the remains in multiple locations.
The confession seemed devastating.
Until investigators started checking it.
The Story Starts Falling Apart
The burial sites were excavated.
Nothing was there.
Details inside the confession also created problems. Some information appeared inconsistent with known facts. Other elements could not be verified at all.
Lyttle’s lawyers argued that he had simply told the undercover officers what they wanted to hear. They claimed he had become so invested in joining the organisation that he invented a story to satisfy its leaders.
The Crown argued the opposite.
Why would an innocent man confess to such horrific acts? Why provide details no one had suggested to him? Why repeatedly maintain the story?
The case became a battle over a question that continues to divide legal experts around the world:
Can a false confession sound completely real?
Guilty. Then Not Guilty.
In 2019, a jury found Lyttle guilty of murder.
But the story didn’t end there.
The conviction was later overturned by the Court of Appeal, which criticised aspects of the police operation and raised concerns about the psychological pressure placed on Lyttle during the sting.
Eventually, the murder charge was dismissed.
More than a decade after Brett Hall disappeared, nobody has been convicted of his death.
Hall’s body has never been found.
And the confession that once seemed to solve the case remains trapped in legal limbo — viewed by some as a chilling admission of guilt and by others as a textbook example of how powerful psychological manipulation can produce a false confession.
The Question That Remains
The David Lyttle case is no longer just a murder mystery.
It’s become a test case for one of policing’s most controversial tactics.
Supporters say Mr Big operations can crack cases that would otherwise remain unsolved forever.
Critics argue they create exactly the conditions in which vulnerable people may confess to crimes they never committed.
Somewhere between those two possibilities lies the truth about what happened to Brett Hall.
And after all these years, that truth remains missing.
