Murder and Guilty Plea
On April 8, Zack Coughlan, 23, ambushed his housemate Jamie Collins, 21, in the garden of their Filton home. Collins, a final-year robotics student at UWE Bristol, was stabbed more than 30 times and left in an alleyway. Coughlan cycled away on Collins’s bike, discarded it at a retail park and threw his blood-stained clothing into a pond weighted with bricks. He later returned, put a pizza in the oven, played video games and called 999 several hours later to report finding the body.
Coughlan initially denied murder but changed his plea to guilty after the judge ruled that a manslaughter defence could not be considered. He was sentenced at Bristol Crown Court to life imprisonment with a minimum term of 28 years.
Planning and Pre-Murder Actions
The court heard Coughlan had prepared the attack for weeks. On March 27, he bought black clothing and shoes and searched the internet for “what corpse looks like”. The night before the killing he changed into the black outfit in a nearby alley to conceal his identity. On April 7, Coughlan asked Collins to leave the house, claiming Collins brandished a kitchen knife and threatened him.
Trial Proceedings and Sentencing
Judge Mr Justice Linden rejected Coughlan’s claim that Collins had threatened him, describing Collins as “a gentle soul” and noting that the motive remained unknown. He ordered Coughlan to serve at least 28 years, emphasizing the lasting emotional scars inflicted on Collins’s family.

Impact and Reactions
Collins’s death prompted an outpouring of grief from university friends, staff and the robotics community. Attendance at his memorial and the trial underscored his popularity. The family repeatedly stressed the senselessness of the crime and their disappointment that Coughlan had pretended to help while committing the murder.
Conflicting Reports & Gaps
