London, Mar 8 (ANI): Murdered Harry Potter star Rob Knox's father has branded his son's killer 'spineless scumbag.'
Karl Bishop was given life sentence after he was convicted of the attack on Rob, reports the News of the World.
Rob had been stabbed five times in the chest by Bishop, 22, outside the Metro bar in Sidcup, south east London, in May last year.
Bishop never once showed a sign of remorse, repeatedly laughing and giving thumbs-up signs to pals at the Old Bailey in London.
Referring to Bishop's disgusting conduct in court, Colin Knox said: "I thought, 'You spineless, gutless, coward. Now everyone knows what you are.'"
"That was one of the worst things. There was no sorrow, no regret and no respect for our family.
"I hate him. I hate what he has taken from me and I hate how he acted in that courtroom.
"He's nothing more than a scumbag and I don't like to waste time thinking about him," he added. (ANI)
