Two hitmen who stabbed schoolboy Aamir Siddiqi to death by mistake in 2010 were handed a minimum term of 40 years today.
Ben Hope and Jason Richards from Cardiff were each paid £1,000 to murder a middle-aged family man who owed money to a shady businessman.
But the "hit" went wrong when the killers went to the wrong Cardiff address and murdered the teenager by mistake.
The 17-year-old's frantic parents, Iqbal and Parveen, fought to save their son but were knifed in turn by the killers.
The pair both protested their innocence during their trial but a jury unanimously found them guilty of Aamir's murder as well as the attempted murder of his parents.
