It took less than three hours for the jury in the Aaron Pajich murder trial to find two women guilty of murdering the Orelia teenager.
A serial-killer obsessed woman and her bondage-loving housemate were found guilty on Wednesday of murdering autistic teenager Aaron Pajich.
The 18-year-old's body was found buried in a shallow grave in the backyard of their Orelia home on June 13 last year.
26-year-old Jemma Victoria Lilley and 43-year-old Trudi Clare Lenon were on trial in the WA Supreme Court for the past four-and-a-half weeks.
The pair will be sentenced in February.
