Student Who Stabbed Housemate 30 Times Jailed for Life 2026

A university student who lay in wait for his housemate and stabbed him 30 times has been jailed for life. Zack Coughlan, 23, was sentenced at Bristol Crown Court to a minimum term of 28 years for the murder of Jamie Collins, 21.

The attack happened in Filton, South Gloucestershire, on 8 April this year. Coughlan, dressed in black and wearing a mask and gloves, ambushed Collins in the garden of their shared home as Collins returned from university.

What Happened in the Filton Ambush?

Collins was cycling home from the University of the West of England (UWE) Bristol, where he studied robotics alongside Coughlan. Shortly before 6pm, as he arrived at the house, Coughlan launched a premeditated attack.

Prosecutor Adam Vaitilingam KC described it as a "carefully planned and cold-blooded execution." Collins was stabbed repeatedly and left dying in an alleyway as Coughlan cycled away on his victim's bike.

Coughlan dumped the bike at a nearby retail park, bought a change of clothes, and threw his bloodstained clothing into a pond in carrier bags weighed down with bricks. He then returned to the house they shared.

Who Was Jamie Collins?

Jamie Collins was a 21-year-old robotics student at UWE Bristol. The judge, Mr Justice Linden, described him as a "gentle soul" who was "caught totally unaware" and was "utterly defenceless" during the attack.

Collins had no known conflict with Coughlan, and the judge said no one would ever know why Coughlan killed him. The court heard Coughlan had denied murder and a trial was underway, but he changed his plea to guilty on Tuesday.

The Trial and Sentencing

Coughlan initially pleaded not guilty to murder, but changed his plea to guilty on Tuesday. Sentencing him on Wednesday, Mr Justice Linden dismissed Coughlan's claim that Collins had previously threatened him.

The judge handed down a life sentence with a minimum term of 28 years. This means Coughlan will not be considered for parole until he has served at least 28 years.

Key Facts of the Case

• Victim: Jamie Collins, 21, robotics student at UWE Bristol.
• Perpetrator: Zack Coughlan, 23, also a robotics student at UWE.
• Attack: Ambushed in the garden of their shared home in Filton on 8 April.
• Weapon: Knife used to stab Collins 30 times.
• Sentence: Life imprisonment with a minimum term of 28 years.
• Plea: Coughlan changed his plea to guilty mid-trial.

Why This Case Matters

This case highlights the devastating consequences of premeditated violence. The judge's comments about Collins being a "gentle soul" underscore the senselessness of the attack.

It also raises questions about safety in shared student accommodation and the importance of addressing mental health and conflict resolution among young adults. The fact that Coughlan tried to cover his tracks—dumping the bike, changing clothes, and disposing of evidence—shows a chilling level of calculation.

The case has drawn attention to knife crime in the UK, particularly among young people. According to the Office for National Statistics, knife-enabled crime has been rising in recent years, though it remains lower than a decade ago.

Comparison of Similar Cases

This case is reminiscent of other student-related stabbings, such as the Bristol housemate stabbing and the Brisbane school stabbing. Both involved young people and shocking violence.

What to Watch Next

The sentencing brings closure to the Collins family, but questions remain about why Coughlan committed such a brutal act. The judge noted that no one would ever know the reason.

As the case concludes, attention may turn to knife crime prevention and support for victims' families.
