Jemma Lilley and Trudi Lenon have been sentenced to life in prison with a minimum for 28 years for murdering Orelia teenager Aaron Pajich
The pair appeared at Western Australia's Supreme Court earlier today where they were read their sentences for murdering the teenager in June 2016.
Ms Lilly and Ms Lenon stabbed the 18-year-old autistic teenager to death before burying him under a slab of concrete in the backyard of their Orelia home.
The pair was found guilty at a 5 week trial last year but Lilly claimed she was asleep in another room at the time of the murder, and only discovered Mr Pajich's body after she woke up.
During the trial a court heard the pair were obsessed with death and Ms Lilly was writing a serial killer trilogy.
Lenon appeared in court with no visible injuries since she was attacked with boiling water at Bandyup Women's Prison on New Year's Day.
