Student who stabbed housemate 30 times admits murder

A student who stabbed his housemate more than 30 times in a masked ambush has changed his murder plea to guilty. Zack Coughlan, 23, attacked Jamie Collins, 21, in an alleyway near the garden of their home on 8 April and then left his body outside for eight hours before calling police. A murder trial had been under way at Bristol Crown Court because Coughlan initially denied the charge, although he did admit killing Collins. He told jurors he stabbed Collins because he feared his housemate would kill him . However, Coughlan, of Cleve Road, Filton, has now changed his plea to guilty and will be sentenced for murder on Wednesday.
