Third trial expected over WA woman's death November 8, 2013 - 5:54PM An elderly man is expected to face a third trial over the death of a 42-year-old woman in Western Australia more than 20 years ago after a jury could not reach a verdict. Ronald Leslie Pennington, 84, had been on trial in the WA Supreme Court for the July 1992 manslaughter of Cariad Anderson-Slater, whose remains were found in his former backyard in February 2011. Pennington had moved to Tasmania, but was extradited to Perth to face the charges. He was convicted of manslaughter after a trial in March last year, and was sentenced to eight and a half years in jail. But the conviction was quashed by the Court of Appeal because the trial judge erred in his directions to the jury. Pennington faced a retrial, but the jury was discharged on Friday because it could not reach a verdict.
