A nurse who moonlighted as a drug dealer has avoided spending any time behind bars after being busted suppling cannabis and methamphetamine. Leiha Marie Walker, 44, had been working as a nurse in Townsville until January when she had to stop working for health reasons. The New Zealand born woman was sentenced on Thursday in Townsville District Court on 11 counts of supplying a dangerous drug after pleading guilty. Walker was stopped by police while driving in the early hours of May 28, 2017.
