A 23-year-old university student has pleaded guilty to murdering his housemate in a brutal stabbing attack, ending a trial at Bristol Crown Court. Zack Coughlan admitted to the killing of Jamie Collins, 21, who was attacked in an alleyway near their shared home on 8 April and left to die outside for eight hours before emergency services were called. According to BBC News, Coughlan will be sentenced for murder on Wednesday.
The pair were final-year robotics students at the University of the West of England, and Coughlan owned the house they shared with another student, Charlie Latimer. Initially, Coughlan had denied the murder charge while admitting he killed Collins, claiming during trial that he acted in self-defence after fearing his housemate would harm him following a dispute over rent.
The attack itself was carried out with extreme violence. Coughlan stabbed Collins more than 30 times in what appeared to be a masked ambush, then cycled away after leaving the body outside. He returned home and spent the following hours eating pizza and playing video games, telling the court he needed to "disconnect" from what had happened. Only after eight hours did he contact police.
What was Coughlan's defence?
Throughout the trial, Coughlan maintained he had acted under duress, telling jurors he felt he "had no choice" and was "barely able to think" when he decided to wait for Collins to return from university before attacking him. He claimed Collins had become increasingly extreme in his political views and had threatened to kill him. However, Coughlan told the court he watched the CCTV footage of the killing five times between 20:00 and 01:00, saying he was trying to "make sense of it all".
Four days before the fatal attack, Coughlan reported to police that men had pulled a knife on him in the garden. He said he did not report Collins's alleged threats because police had not listened to him during that earlier incident.
What evidence undermined his account?
Detective Chief Inspector Lucy Edgeworth of the major crime investigation team challenged Coughlan's version of events, pointing to multiple inconsistencies. She stated that all available evidence suggested the killing was a "pre-planned, cold-blooded execution" rather than a spontaneous act of self-defence.
Edgeworth highlighted that CCTV footage showed Coughlan had changed his shoes after the attack, yet he had given no indication to investigators that he had changed his trainers. She described this as "just one of many things that then began to unravel with his account". She also noted as "slightly odd" his claim that he had injured his hands climbing a tree after the incident.
While acknowledging that a dispute over rent existed between the two men and that they held different political views, Edgeworth said these factors did not explain such a horrific crime. "We know there was a dispute about rent. We know that they held different political views. But none of those things make any sense to why somebody would carry out such a horrific crime," she said.
Why did Coughlan change his plea?
The decision to plead guilty came after the trial had already begun at Bristol Crown Court, where Coughlan had initially contested the murder charge. His change of plea brings the proceedings to an end before a jury verdict, with sentencing now scheduled for Wednesday. The guilty plea represents an acknowledgement of responsibility for the killing, though it does not necessarily indicate acceptance of the prosecution's characterisation of the crime as premeditated.
