The woman who murdered an autistic teenager has lost her appeal against conviction.
Jemma Lilley and her housemate Trudi Lennon strangled and stabbed 18-year-old Aaron Pajich-Sweetman after he went missing in Rockingham, before burying him in a shallow grave in their Orelia backyard and covering it with concrete and tiles.
The women blamed each other for the murder, but a jury found them both guilty in less than three hours.
Lilley appealed for her life sentence conviction to be overturned, with the court on Tuesday denying the appeal.
