Zack Coughlan given 28-year minimum term for killing Jamie Collins

What happened

Zack Coughlan must spend at least 28 years in prison after admitting the murder of Jamie Collins, the fellow student he attacked as Collins arrived home from university. Mr Justice Linden imposed a life sentence at Bristol Crown Court on Wednesday.

Collins, 21, suffered 30 stab wounds in the garden of the house the two men shared in Filton, South Gloucestershire. He had cycled back from university shortly before 6pm on 8 April, unaware that Coughlan was waiting for him.

For the attack, Coughlan, 23, had concealed his appearance with a mask, gloves and black clothing. The judge found that he had intended to kill Collins and had been preparing to do so for some time.

Coughlan initially contested the murder charge, and jurors had begun hearing the case against him. He admitted the offence on Tuesday, changing his plea before the trial had reached a verdict.

In sentencing him the following day, Mr Justice Linden said the prosecution case had reached the point where a conviction was inevitable. He also found that Collins had been taken completely by surprise and had no means of defending himself.

The background

The men were in the final year of robotics studies at the University of the West of England in Bristol. Their shared accommodation was a three-bedroom house owned by Coughlan, valued at £300,000.

Collins was originally from Swansea and was close to finishing his degree work. Only two coursework assignments remained before he was due to leave Bristol and return to his family in Wales.

His father, Rob Collins, had already arranged an engineering job for him. The move home would therefore have brought both the end of his university studies and the start of work in a field connected to his training.

Coughlan, who is half Danish, had spent his childhood with his family in Cork, Ireland. He moved to Bristol at 19 to study robotics, before becoming Collins's housemate as well as a fellow student.

Police established that the men had disagreed about rent and held different political opinions. Those differences formed part of the investigation into their relationship, but detectives did not identify a clear motive for the murder.

During his evidence, Coughlan alleged that Collins had threatened to kill him. He presented the decision to wait for Collins and attack him as a response to fear, claiming that he believed he had no alternative.

Mr Justice Linden rejected that account. He found that Collins had neither acted nor spoken in a way that would have led Coughlan to believe he posed a threat of violence. Other evidence described a young man who avoided confrontation.

How the evidence fitted together

After stabbing Collins, Coughlan left him dying in an alleyway behind the property and rode away on Collins's bicycle. He abandoned the bike at a nearby retail park, then bought replacement clothes.

He put his bloodstained clothing into carrier bags with bricks and threw them into a pond. The weighted bags were part of his efforts to dispose of evidence before returning to the house.

By about 9pm, Coughlan was back at the property. He put a pizza in the oven and joined friends for online gaming. In court, he explained his behaviour as an attempt to detach himself from what had happened.

He waited until around 2am to telephone 999, roughly eight hours after the attack and five hours after coming home. During that call, he claimed to have just discovered Collins's body in the garden.

Cameras installed at the house had recorded the killing. Coughlan showed the footage to the officers who attended, and they initially dealt with him as a witness. Jurors also heard that he watched the recording five times afterwards.

Physical and digital evidence helped establish his movements. His blood was found on Collins's bicycle, while analysis of his mobile phone corresponded with the route taken by the attacker in CCTV recordings after the stabbing.

Coughlan also had wounds on his hands. When people noticed that he was bleeding, he told them he had injured himself falling while climbing trees, offering an explanation unrelated to the attack.

In a further interaction after the murder, Coughlan told a university friend that he wanted to organise a memorial for Collins. His presentation of himself as a concerned housemate later became a particular source of distress for the family.

What people are saying

Prosecutor Adam Vaitilingam KC argued that the attack was a deliberate killing involving careful preparation. Detective Chief Inspector Lucy Edgeworth, of the major crime investigation team, likewise said the evidence pointed to a planned murder rather than a spontaneous confrontation.

Edgeworth addressed Coughlan's allegations that Collins's politics had become more extreme and that he had spoken about killing him. She said the known disagreements over money and political views did not explain the violence that followed.

The judge described Collins as someone concerned with wider social and international problems. His assessment of Collins's character contrasted sharply with the threatening figure Coughlan had sought to portray during the trial.

Collins's stepmother, Lisa Jane Collins, described the consequences for the family in a statement read to the court. Police arrived at their home early on the morning after the attack to tell them he had died.

The adults then had to wake Collins's siblings and explain that their brother had been killed. Lisa described having to deliver that news while the family themselves were still learning what had happened.

She said the stress left Rob unable to work. His business subsequently failed and he was left in debt, adding financial consequences to the family's bereavement.

Attending the trial also caused Lisa physical distress. She said she had been sick twice after hearing details of the violence and found Coughlan's efforts to depict himself as the victim particularly painful.

In a separate family statement following the guilty plea, relatives described the lasting harm caused by repeatedly having to explain Collins's death to others. They also expressed revulsion at Coughlan's pretence that he had tried to help him.

What happens next

The 28-year minimum term is not a fixed release date. For an adult convicted of murder in England and Wales, a life sentence is mandatory; the minimum term determines when release can first be considered through the parole process.

Once that minimum period has been served, the Parole Board assesses whether continued detention remains necessary to protect the public. A prisoner serving a life sentence can remain in custody beyond the minimum term if the conditions for release are not met.

If released, a life-sentenced prisoner remains on licence for the rest of their life. Release carries conditions and the possibility of recall to prison; it does not bring the sentence itself to an end.

Why this matters

For readers following criminal cases, the distinction between a minimum term and the full sentence is important. Coughlan's punishment places both an initial restriction on liberty and a lifelong legal framework around any eventual release.

For students sharing accommodation, the circumstances place this case close to everyday university life: study, rent and a home shared with a coursemate. The court's findings were specific, however: the judge rejected Coughlan's claimed fear of Collins rather than accepting it as an explanation for the killing.
