LABOURER Dennis Mackenzie was found guilty of the murder of a young girl and a young woman following a trial at the High Court in Inverness in December.
The body of Susan Redmond (10) was found in the hall cupboard of a house in Coronation Park where Mackenzie had been staying when she was last seen on July 13.
Mackenzie, of Craigton Avenue, denied the charge of raping and murdering her as a result of her injuries.
He also denied murdering 26-year-old barmaid Lesley Lobban, of Smith Avenue, at woodland on Dochfour Estate near Blackfold Brae, on August 13/14.
The jury of eight men and seven women returned unanimous verdicts of guilty on each charge after 40 minutes.
Judge Lord Robertson sentenced Mackenzie to life imprisonment on both counts with a recommendation that he should serve a minimum of 15 years.
"These were terrible crimes. You are clearly a menace to society," he told Mackenzie.
