A woman whose home was believed to have been set alight by her former partner has died in hospital, police have said.
Tracy Jones, 40, had been receiving treatment for severe burns caused by the fire in September at her Altrincham home, in which her son Shaun, 15, died.
She had been induced into a coma but died in Whiston Hospital on Friday.
Her ex-partner, Dave Potts, 39, died from burns shortly after the blaze. He had reportedly set himself alight at her house in Barlow Road, Broadheath.
Ms Jones's other children, who were in the house at the time, continue to receive treatment for their injuries.
Daughter Cailin, 18, remains in hospital where police said she is making a "gradual recovery", having awoken from a coma. Son Zachary, four, has been discharged but continues to receive daily medical aid.
The Independent Police Complaints Commission is reviewing the case, after it emerged Ms Jones contacted police five times in four weeks before the blaze.
A Greater Manchester Police spokesman said: "A joint investigation between police and Greater Manchester Fire and Rescue Service continues."
