inputs: hypothesis: Jahche Broughton is the murderer of Miss Aim. premise: Jahche Broughton, 15, was sentenced to life imprisonment and ordered to serve at least 12-and-a-half years behind bars for the murder on January 17 last year.  Miss Aim, 26, from Orkney, was killed as she made her way home from a night out with friends in the North Island resort of Taupo.   She suffered serious head injuries and later died in hospital.  A judge at the High Court in Rotorua told Broughton that the sentence took into account his age and guilty plea.  The teenager was 14 when he carried out the murder and is believed to be one of the youngest convicted criminals in New Zealand to be given a life sentence.
