The three of them kicked, stamped on and punched the victim for nearly 15 minutes yet somehow chose to plead not guilty to murder... then they all chose not to stand in the witness box to utter a word in their own defence. The prosecution barrister implied in his opening address that the female, who was 16 at the time, was the scummiest human among the defendants, which is remarkable as one of the others, Strickland, is a career thief, aggressive beggar and home burglar.
By going not guilty and wasting everyone's time running a trial the judge is free to hammer them to the maximum the law allows in his sentencing. The males are likely to get 32 to 35 years minimum, she'd be lucky to receive anything below 16 years minimum.
