The mother of murdered teenager Christopher Cave said her son's killer should have hanged for his crime.
Christopher Cave had been out with a friend before the attack
Sean Matson, 20, from Langthwaite Walk, Redcar, confessed to the murder of the 17-year-old at Teesside Crown Court on Tuesday after originally entering a not guilty plea
Matson was sentenced to life imprisonment for stabbing Christopher on 5 June 2003 in Burnmoor Close, Redcar, with an eight-inch kitchen knife.
Christopher, described by police as a "hardworking, respectable 17-year-old"
was rushed to Middlesbrough General Hospital where he later died.
His mother Theresa said her son had his whole life ahead of him.
She said: "If I had my way he would be hanged and I would be the hangman, but the system does not work that way.
"A life sentence means life to me, he should spend every day of his life behind bars just because of what he did to Chris.
"I know Chris would want him to spend the rest of his life in jail as well - every single day of it so he can't do it to nobody else."
