In the quiet suburb of Stafford, a chilling event would forever be etched in local history as the setting of one of the most perplexing crimes.
In 1971, what initially appeared to be an unfortunate roadside accident quickly unravelled into a calculated murder, meticulously staged with fruit boxes as bait. The events that unfolded on Shand Street not only shook the local community but also showcased the growing sophistication of forensic investigation in Australia.
The Scene on Shand Street

At first glance, it seemed as though Mr Cooper’s vehicle had swerved to avoid the obstruction, resulting in his untimely demise. However, sharp-eyed investigators quickly identified inconsistencies—spent bullet shells near the body, entry wounds inconsistent with an accident, and the deliberate arrangement of the fruit boxes.
The Queensland Police Scientific Section stepped in, meticulously reconstructing the scene. Their findings painted a chilling picture: the fruit boxes were not carelessly strewn about but strategically placed to force Mr Cooper to stop his vehicle. The crime scene reconstruction also demonstrated that a single person could have dragged Mr Cooper’s lifeless body into position, dismissing earlier suspicions of multiple perpetrators.

A Key Witness and a Breakthrough
While investigators pieced together the physical evidence, a breakthrough came from an unlikely source. A New Farm resident reported seeing a man removing fruit boxes from the New Farm Fruit and Vegetable Market the night before the crime. This seemingly innocuous detail turned out to be the thread that unraveled the case.
Ballistics experts identified a .22 calibre rimfire Armalite auto-loading rifle, modified with a silencer, as the weapon used in the murder. The sophistication of the modification spoke to premeditation and cold precision.
The Motive: Greed and Desperation
As the net closed in, suspicion fell on Donald John Maher, a Brisbane printing business owner who was drowning in financial ruin. Investigations revealed that Mr Maher was aware of significant funds being held at the National Hotel and had hatched a plan to ambush Mr Cooper, believing he carried the keys to the hotel’s safe.
However, on 26 September 1971, it was the assistant manager’s turn to hold the safe’s key, which would have contained approximately $16,000. Mr Maher’s plan was foiled when Mr Cooper did not have the key, and in a moment of panic, Maher fired the fatal shots.
A $10,000 reward was offered for information about Mr Cooper’s slaying, along with a free pardon to any accomplice who provided information, as long as they had not caused the murder.
The Trial and Aftermath
In November 1971, Mr Maher was charged with Mr Cooper’s murder. By May 1972, following a month-long trial, he was found guilty and sentenced to life imprisonment with hard labour.
During the trial, Perry Alan Vincent, a convicted bank robber, testified that Mr Maher had offered him $10,000 to falsely implicate Detective Sergeant Glen Hallahan in the crime. Mr Maher countered, claiming Vincent and others had threatened him and even crashed into his car weeks before the murder.
Controversies Behind Bars
In 1976, Mr Maher was controversially granted temporary leave from prison to attend a Neil Diamond concert. In the early 1980s, it was revealed he had been commuting unaccompanied to Queensland University to attend lectures. While imprisoned, Mr Maher completed high school, earned a Bachelor’s degree in psychology, and began a PhD in advanced mathematics.
Despite his education and release in 1987 after serving 15 years, Mr Maher continued to claim he did not pull the trigger, insisting he knew who did but would not reveal the name, citing safety concerns.
Journalist Steve Bishop’s 2012 book “The Most Dangerous Detective” later alleged that Detective Sergeant Glen Hallahan may have been involved in Mr Cooper’s murder, adding yet another layer of intrigue to the Stafford case.
Stafford Remembers
The Stafford ambush remains a defining moment in the suburb’s history—a grim reminder of human greed, but also a testament to the evolution of forensic science and investigative diligence. Today, the streets of Stafford bustle with suburban life, but the echoes of 1971 linger as a haunting chapter in Brisbane’s criminal past.
As the years pass, the Stafford ambush serves as both a cautionary tale and a reminder of the relentless pursuit of justice by Queensland’s law enforcement—a story of tragedy, resilience, and ultimately, resolution.
