A baby boy who was left fighting for life after a fire at a flat has become the third child to die in the blaze.
Charlie Timbrell, aged one, was being treated for his injuries at Alder Hey hospital in Liverpool.
His mother, Lee-Anna Shiers, 20, was killed along with her niece Skye Allen, two, and nephew Bailey Allen, four, after the blaze took hold at their first-floor flat in Prestatyn, North Wales, on Friday night.
Miss Shiers' partner Liam Timbrell, aged 23, is also being treated in hospital. Firefighters managed to rescue Mr Timbrell and his son from the property.
Charlie died surrounded by his family.
Family members earlier brought flowers and teddy bears to the scene and gathered there for around 45 minutes looking at floral tributes and reading messages of condolence.
They said they were too upset to comment on the tragedy.
At the local Christ Church, special prayers were said as part of the Sunday service.
Police forensic officers have been at the flat in Maes y Groes carrying out investigations.
A 45-year-old man and a 42-year-old woman, who are tenants in the downstairs flat, continue to be questioned on suspicion of murder.
Firefighters took the five victims from the flat at 10pm on Friday.
A Welsh Ambulance Services spokeswoman said the survivors were taken to Glan Clwyd Hospital.
Mr Timbrell, who remains in a critical but stable condition, was later transferred to Whiston Hospital, Merseyside.
Detective Superintendent John Chapman said: "My heart goes out to the family and our thoughts are with them at this difficult time."
One woman, who lives close by, said a neighbour had tried to mount a rescue as fire crews rushed to the scene.
The woman, who declined to be named, said: "There were two large bangs and at first I thought it was a car crash because the road at the end of Maes Y Groes is quite busy."
