The children of a man stabbed to death outside a Norwich car park say no sentence will will be severe enough to make up for their dad's death.
David Hastings was murdered in June last year by Rolands Heinbergs who repeatedly stabbed him on Rose Lane in June 2018.
He has now been sentenced to a minimum of 28 years in prison for murder.
Norfolk police say it was a shocking and appalling crime and that Heinbergs had showed no remorse for what he had done.
"There's no sentence that is severe enough to make up for my dad's death, knife crime is a big problem and how many more lives are going to be lost through knife crime before the Government actually realises that this is serious and the sentences need to be firm and hard."
ITV News Anglia spoke to Kyle and Kimberley Hastings after the sentencing at Norwich Crown Court.
Rolands Heinbergs, aged 23 and of no fixed address, was found guilty of murdering David on Rose Lane in Norwich following a two week trial.
He was sentenced to life imprisonment to serve a minimum of 28 years.
"Our thoughts are with David’s family and friends who have lost him in such terrible circumstances and whist it is still unknown what triggered Heinbergs to act in this violent and senseless way, I hope this sentence will go some way in helping them during this difficult time.”
