Fire crews were called to a property at Chermside in the city’s north on Wednesday just after 4am when neighbours raised the alarm.
One spotted Alexis Parkes inside the home after hearing her screams, but the intensity of the blaze meant they couldn’t reach her in time.
“Firefighters gained entry, conducted a search and rescued the 50-year-old female resident,” Queensland Police said.
Crews administered first aid before Ms Parkes was rushed to Royal Brisbane and Women’s Hospital in a critical condition with extensive burns.
Tragically, Ms Parkes died on Sunday morning.
Police allege her partner, James Morton Mason, 43, deliberately lit the fire at her Bundal St residence in the early hours of February 5 and charged him with a range of domestic violence offences and attempted murder.
The latter charge has been upgraded following Ms Parkes’ death, and the man will appear in Brisbane Magistrates Court today.
Ms Parkes’ four children, Tyron, Cameron, Mackayla and Brandon Parkes, told The Courier-Mail newspaper that they were devastated by the loss of their mother.
“This loss has hit the family very hard, especially because (we) lost (our) father tragically at a young age,” they told the paper.
