Aged care nurse Roger Dean has pleaded guilty to 11 counts of murder as a result of starting two fires in the Quakers Hill Nursing Home on November 18, 2011. Three residents died in the fire and a further eight succumbed to their injuries. Dean, aged 37, had stolen $87 worth of drugs over the previous week and an audit had discovered they were missing and enquiries commenced. He tore up sheets into separate rooms and lit them in the belief that the fire would destroy the medicine cabinet. He is awaiting sentencing.
