Michelle Pearson's grief-stricken mother has paid a heartbreaking tribute to the petrol bomb victim, saying the tragic mum "needed her children more".
Ms Pearson, 37, died 20 months after four of her five children were killed in a December 2017 arson attack that left her with horrific burns to 75 per cent of her body.
Her devastated family spelled out her name in lit tealights as they gathered to mourn their loss and reflect on Monday night.
Ms Pearson's mum, Sandra Lever, posted a photo of the touching scene, writing on Facebook : "I am proud to have you as my daughter Michelle I miss you so much but you needed the children more you gained your wings and joined them you suffered for so long it now time to be put at piece love you XX."
Mrs Lever had announced Ms Pearson's death earlier in the day, saying she died on Sunday night after "a hard 20 months of fighting" following the attack on her home in Salford, Greater Manchester.
Her condition took a turn for the worse in June, when her family revealed that she was "critical" in hospital.
Ms Pearson, from Walkden, had been in hospital since the December 11, 2017, fire which killed her children Lia, three, Lacie, seven, Brandon, eight, and Demi, 15.
Greater Manchester Police is reviewing the original investigation and will consult the Crown Prosecution Service to determine whether a fresh murder charge is warranted.
Among the many tributes, Ms Pearson's niece, Courtney Pearson, wrote: "Our beautiful Michelle gained her wings last night, she held on, but her children needed her more."
Zak Bolland, 24, and David Worrall, 26, were both convicted of four counts of murder and jailed for life, with minimum terms of 40 and 37 years, respectively.
They were also convicted of the attempted murder of Ms Pearson, her son Kyle, then 17, and his friend, Bobby Harris, who both escaped through an upstairs window.
Ms Pearson and her daughter Lacie, who were sleeping in the same bedroom, were rescued from the burning home just two weeks before Christmas.
The mum woke up and screamed "Not the kids! Not my kids!" and dialled 999, but she was overcome with heat and smoke before completing the call.
Lacie died in hospital two days after the fire.
All four children "died a terrible death" from smoke inhalation and burns, the killers' trial heard.
Bolland's then-girlfriend, Courtney Brierley, was jailed for 21 years for manslaughter and lost an appeal against her conviction.
The trial at Manchester Crown Court heard Bolland had been involved in a "petty" feud with Kyle over damage to a £200 car, prompting a series of tit-for-tat attacks.
A jury was told Bolland and Worrall were fuelled by drink and drugs as they filled two glass bottles with £1.50 of petrol bought from a local garage, stuffing the tops with tissue paper as they prepared the attack at 5am on December 11 2017.
Two lit petrol bombs were thrown inside the Pearsons' home after the kitchen window was smashed.
Bolland hurled his bottle which "exploded" near the stairs, blocking the only exit to the ground floor and trapping the victims upstairs.
Within seconds, flames engulfed the three-bedroom mid-terrace home.
There have been calls for the attackers to face a fresh murder charge.
Former chief prosecutor Nazir Afzal tweeted: "Those convicted of the murder of her children now need to be charged with her murder.
"Time is no longer a bar to prosecution.
"Such a sad case."
