The family of an aged care nurse killed in a fatal car crash by a young woman on drugs say they are devastated she has escaped conviction on a drug driving charge. Kay Shaylor, 62, was killed on September 3, 2016, when her car was hit head-on by a Commodore being driven by Bianca Harrington, who was 20 years old at the time. Harrington’s Learner licence had been suspended at the time of the crash. Blood tests showed Harrington had taken a cocktail of drugs including amphetamine, methamphetamine and cannabis. In a police interview she admitted smoking five bongs of pot the night before. Judge Rodney Madgwick said he couldn’t be convinced beyond a reasonable doubt that Harrington was “very substantially impaired.”
