A LAKE Boga woman has died after suffering burns to 40 per cent of her body, Swan Hill police said.
Criminal Investigation Unit Detective Senior Constable Mal Simpson said the woman in her early 70s died on Thursday night at The Alfred hospital.
"We will now prepare a report for the coroner," he said.
The woman was severely burnt when a grass fire ignited her clothes.
Swan Hill fire brigade operations officer John Breaks said it was believed the woman was using an incinerator to burn rubbish.
"The fire has then spread out from the incinerator," he said.
“The initial indication is that the fire may have been the result of burning off rubbish and it caught the grass, which caught her clothes."
Ambulance Victoria spokesman John Mullen said the patient had suffered burns to 40 per cent of her body.
