The family of a teenage schoolgirl who was murdered by her jealous ex-boyfriend said they were let down by the justice system after he was jailed for at least 12 years.
John Wilson, 20, stabbed 17-year-old Michelle Stewart ten times in front of her friends in a street in Ayrshire last November.
He was given a life sentence at the High Court in Glasgow after he had earlier admitted murder.
The teenager's father Kenneth said his daughter had been "completely let down" by the system.
Mr Stewart, 48, added: "He stabbed my daughter ten times. She was going to be 18 next week and she had her life in front of her.
"I've got to go to the graveyard and put down 18 roses on my daughter's grave for her 18th birthday, that's all we've got left.
"That guy will get out in 12 years but we've got the life sentence. I would have expected at least a 17-year sentence for every year Michelle has lived.
"When you are 17 or 18 the world is in front of you, but it was all taken away from her." Miss Stewart's mother Josephine wept as she said: "He has taken away my child."
The victim's brother Kenny, a nurse who tried to help his sister at the scene, added: "He will be out after 12 years. We will never get Michelle back. Life should mean life, like it does in America.
