Elderly man faces WA manslaughter sentence

An elderly man who faced four trials over the death of a woman in Perth more than 20 years ago is about to be sentenced for his crime.

Ronald Leslie Pennington, 86, was found guilty in July of unlawfully killing 41-year-old Cariad Anderson-Slater in 1992.

Ms Anderson-Slater's remains were uncovered 19 years later during earthmoving works in the backyard of the home Pennington had rented.

Lawyer Simon Freitag advised during sentencing submissions in the West Australian Supreme Court earlier this month that his client intended to appeal his conviction.
