A mother whose home was allegedly torched by her jilted lover has died in hospital.
Tracy Jones, 40, had been receiving treatment for the past two months following the blaze in Altrincham, Greater Manchester, which killed her 15-year-old son Shaun.
She had been induced into a coma with severe burns but died in Whiston Hospital on Friday night.
Her ex-partner, David Potts, 39, also suffered serious burns and died a short time after the fire was started in the early hours of September 19.
Mr Potts 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, awoke from her coma but remains in hospital where police said she is making a "gradual recovery", while son, Zachary, four, has been discharged but continues to receive daily medical aid.
A Greater Manchester Police spokesman said: "A joint investigation between police and Greater Manchester Fire and Rescue Service continues."
Police had previously confirmed there had been contact between them and Ms Jones, believed to be over unwanted attention from Mr Potts, in the month before the fire.
The police watchdog, the Independent Police Complaints Commission (IPCC), is investigating how officers dealt with that contact.
