A woman accused of murdering her partner by setting fire to a Gymea granny flat has died three weeks before she was due to stand trial.
Amanda Zukowski was found dead in her home in Sydney's inner west on the weekend. Her death is not being treated as suspicious.
Jeffrey Lindsell, 39, suffered extensive burns in the fire, which broke out about 1.30am on Saturday, October 7, 2018 in the granny flat at the rear of his family's home in San Remo Avenue.
He was rescued from the flat by firefighters, but died in Royal North Shore Hospital two days later.
Detectives from the Financial Crimes Squad's Arson Unit established Strike Force Butler to investigate the circumstances surrounding the fire.
Early in 2019, it was revealed investigators believed the fire was intentionally lit while Mr Lindsell slept, and that two taps had been left running full blast inside the flat, pointing to a second person being present at the time.
Detective Senior Constable Christopher Preston later told the Supreme Court that when Mr Lindsell's father tried to use a garden hose to extinguish the blaze, only a trickle of water came out.
Zukowski, 46, was charged with murder in June 2019 and granted bail to appear in the Supreme Court.
She was due to defend the charge at a trial starting on February 3.
