As reported by Rod Minchin of the Press Association and Estel Farell-Roig, Content Editor of Bristol Live, 23-year-old Zack Coughlan stands trial for the murder of 21-year-old Jamie Collins following an incident on April 8, 2026, in the garden of their shared address in Cleve Road, Filton.
What Occurred During The Alleged Attack In Filton?
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, prosecutor Adam Vaitilingam KC informed the jury that Coughlan dressed entirely in black, wore a mask and gloves, and waited approximately 20 minutes in the garden for Collins to return from the University of the West of England (UWE Bristol).
The court was told that shortly before 6:00 pm on April 8, Collins was repeatedly stabbed in an alleyway adjoining the property. Coughlan subsequently left his dying housemate and escaped the scene using Collins’s bicycle.
How Did The Prosecution Detail The Suspect’s Actions After The Incident?
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, Adam Vaitilingam KC detailed how Coughlan abandoned the bicycle at a nearby retail park, bought a replacement set of clothes, and threw his bloodstained garments into a pond.
Coughlan then returned to the residence on Cleve Road around 9:00 pm, where he put a pizza in the oven and engaged in online gaming with acquaintances.
Adam Vaitilingam KC told the jury:
“A few hours later he decided it was time to call the police and pretend that he had just found his friend’s body in the garden. At about 2am – eight hours later – the defendant called 999. He said that his friend had been stabbed. They told him to do CPR until paramedics arrived and he told them that he was.”
What Evidence Led Police To Shift Coughlan From Witness To Suspect?
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, armed police officers arriving at the scene discovered Collins’s body in the rear garden. Coughlan initially claimed to officers that he had returned home from a local park, noticed the back gate open, and discovered his housemate.
However, the property was fitted with CCTV cameras, which captured the assault. Coughlan showed the CCTV footage to investigating officers, who initially treated him as a key witness.
Adam Vaitilingam KC explained that forensic examination uncovered Coughlan’s blood on Collins’s bicycle, whilst mobile phone data tracking aligned precisely with the movements of the assailant captured on camera.
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, when questioned regarding hand injuries, Coughlan claimed to acquaintances that he had sustained cuts after falling while climbing trees. Following the forensic and technological findings, police arrested Coughlan on suspicion of murder.
What Was The Nature Of The Relationship Between The Housemates?
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, both young men were final-year students enrolled in the robotics program at UWE Bristol and cohabited in a property owned by Coughlan.
Adam Vaitilingam KC noted that while minor disagreements regarding rent payments and pricing had previously occurred, those issues had been settled.
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, Adam Vaitilingam KC stated:
“There was nothing that any of the friends were aware of that seemed to be a significant problem. They hung out together both in person and online, they did gaming together, they went out together, entirely normal student life.”
What Is The Defence Case Put Forward By Coughlan?
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, Coughlan accepts responsibility for killing Collins and has formally admitted manslaughter, whilst denying the charge of murder.
Adam Vaitilingam KC outlined the defence position to the court:
“We understand that he will say that he had lost control of himself because of things that Jamie had said to him over the previous days and weeks that made him fear for his life. And so, because of his fear of Jamie, he had been unable to stop himself from killing him.”
The prosecution rejected this argument, with Adam Vaitilingam KC stating that the defence “doesn’t even get past first base.”
Adam Vaitilingam KC told the jury:
“Because this was not a killing done by someone losing their self-control. This was a carefully planned and cold-blooded execution. Someone who has lost control doesn’t plan ahead in the way that he did, dressing up so as to avoid being identified and then waiting for 20 minutes outside an address for their victim to appear.”
As reported by Rod Minchin of the Press Association and Estel Farell-Roig of Bristol Live, the prosecutor added that Coughlan’s conduct after the event—disposing of evidence, offering false explanations for his injuries, playing video games, monitoring the property’s CCTV app, and misleading 999 call handlers—demonstrated deliberate calculated control.
Coughlan, of Cleve Road, Filton, South Gloucestershire, continues to deny murder. The trial at Bristol Crown Court remains ongoing.

Background Of The Development
The trial at Bristol Crown Court represents the formal judicial examination of an event that shocked the student community in South Gloucestershire in April 2026. Both the victim, Jamie Collins, and the defendant, Zack Coughlan, were in their final year of higher education studying robotics at the University of the West of England (UWE Bristol).
Living in a private residential property owned by Coughlan on Cleve Road in Filton, the pair shared daily routines, academic studies, and social pastimes typical of university student life. The proceedings mark the transition of the investigation from an initial missing person/unexplained death call at 2:00 am into a full Crown Court homicide trial following detailed digital, forensic, and CCTV investigations by local law enforcement authorities.
How This Development Can Affect UWE Students And The Local Community
This ongoing trial and its ultimate legal verdict carry significant implications for the immediate student population at UWE Bristol as well as the broader residential community in Filton and South Gloucestershire:
- Student Community Safety and Well-being: The tragic loss of a final-year student and the trial of another will likely prompt heightened psychological and counseling support interventions across UWE faculties, particularly within the Department of Engineering and Robotics.
- Private Student Accommodation Governance: The case highlights dynamics surrounding student housing arrangements where one student acts as a landlord to peers. Universities and local housing associations may increase awareness campaigns around dispute resolution services and tenancy support for students living off-campus.
- Neighborhood Vigilance and Security: Residents in the Cleve Road and Filton areas, where extensive student housing mixes with local families, may see increased local police community engagement and heightened emphasis on private home security measures, including CCTV monitoring and neighborhood safety initiatives.
