The first photo of a four-month-old baby who died this week has been released.
Two people have been arrested on suspicion of murdering Keira Mae Jones, whose life support machine was turned off on 14 September.
She had sustained “catastrophic” injuries, according to police, who were called to Barnsley Hospital in May.
Police continue to appeal to information and have made inquiries at a house in Barnsley, where a stretch of road was taped off.
Detective Chief Inspector Phil Etheridge, the senior investigating officer, said: “The injuries suffered by this little girl when she was just two days old were so catastrophic that she could not recover and her life support was withdrawn after four months.”
Family friend Chantelle Robinson said the baby was in hospital from the day she was born, having been put on feeding tubes.
She said she had supported her mother Aimee by donating baby clothes.
Chantelle said: “As far as I know the baby never came home, she was always in hospital.
“There are so many rumours and stories, you don’t know what you can believe.
“I had been in close contact and messaging the mum.”
She described the baby’s death as “just shocking”.
A 31-year-old woman and a 38-year-old man, both from Barnsley, were arrested on suspicion of murder, South Yorkshire Police have confirmed.
They were released on police bail on Wednesday.
A spokesman said: “We continue to appeal for information which could assist our inquiries.”
