David Green, Scotland's Procurator Fiscal for Homicide and Major Crime, said:
“We welcome today’s conviction and the sentence of Andrew Innes for the murders of Bennylyn and Jellica Burke and the rape of a young girl.
“Thanks to the keen instincts of two police officers, Innes’ horrific crimes were discovered. The prosecution was able to put forward a strong case following diligent police work and forensic investigation.
“Careful and thorough case preparation allowed prosecutors to focus proceedings to a narrow range of issues, saving Bennylyn and Jellica’s family some of the further trauma involved in a protracted trial.
“Innes’ crimes are truly appalling and beyond any understanding. Everyone involved in this prosecution has been affected.
“Our thoughts and sympathies are with the family and loved ones of Bennylyn and Jellica as they deal with their pain and grief.”
