The grandfather of a Bristol teenager convicted of killing a man who intervened in a mugging, says his family is devastated over his conviction and sentence.
Grady's family say the murder verdict was excessive
Brian Grady was found guilty of murdering Liam Attwell, a 25-year-old chef, who intervened in a mobile phone robbery on the city's Harbourside in October.
Sentencing 17-year-old Grady last week, the judge at Bristol Crown Court said his release should not be considered for at least 11 years and that the teenager had shown no remorse.
He also singled out the boy's grandfather, telling him to look into his conscience for having given his grandson a knife.
But now Grady's family say they are stunned by the severity of the sentence and may appeal.
They are also taking legal advice over whether to try to have the conviction downgraded from murder to manslaughter.
Brian Revill, Grady's grandfather, told the BBC his family were devastated by the severity of the sentence imposed on the teenager.
"All the family and all Brian's friends are really gutted over it because no way did he deserve that.
"Brian is the average teenager. It's happened and we can't undo that but it wasn't an intentional thing and that's what murder is - the knife wasn't no switchblade, it was a knife what grandfathers give their grandsons. It had a two-inch blade.
"We're not asking for Brian to walk out of this not guilty because he is guilty of something, but not murder.
"I feel terrible because I keep thinking, if I hadn't given him the knife, would this have happened."
