RICKY Enfield, 34, of Queensway, Broadwell, has been given a life sentence for killing 27-year-old Sean Hook at a house in Cyril Hart Way, Coleford on 10th February 2012.
Enfield was convicted on Thursday (July 19) by a 11-1 majority at Bristol Crown Court and sentenced to life imprisonment with a minimum tariff of 17 years.
Detective Inspector Steve Bean said after the trial: "This was a brutal killing that has left the family and friends of Sean Hook devastated and our thoughts are with them at this time.
"The tragic events of that night have touched a lot more people than just those directly involved and had a profound impact on a very close knit community.
"We hope this verdict provides some comfort to all those who have been affected."
Sean Hook's 51-year-old mother Cheryl Waltham said: "We're devastated. It's been a nightmare to us all. It's awful without Sean. He was happy go lucky and will always be my baba.
"I can't think of any words to describe what he (Ricky Enfield) has done. He's disgusting. He's absolutely wrecked my life.
"I feel like he's made me a bag of nerves. I don't want to be amongst people, I don't trust anyone. I don't have any confidence.
"I'm very satisfied with the verdict. He's done the crime now he's got to do the time.
"I'd like to thank police and victim support. They've been very supportive to me."
