The daughters of a 96-year-old woman who died after her bed was set alight in a care home have appealed for information over her "horrific" death.
Edith Stuart died in hospital after the blaze at Cleveleys Park Rest Home in Cleveleys, Lancashire, on 18 October.
Police believe the fire was started by someone setting Mrs Stuart's bed alight and are treating it as murder.
Her daughters Jean Worgan and Shirley Fish appealed for information to help find those responsible.
Mrs Fish, from Poulton, Lancashire, said: "They set fire to mum's bed and walked away, leaving her there.
"It must have been so frightening. She must have been terrified. These are the thoughts that go through our minds.
"I would beg that person to give themselves up. It would help all of us."
"My mum would have been 97 in two weeks' time. She was really happy, really content. She was looking forward to being 100 years old, she wanted a telegram from the Queen."
A woman, 27, and a girl, 17, were held on suspicion of murder but were released without charge days later.
Mrs Worgan, of Northampton, said the family had taken a lot of thought over choosing a care home for her mother when she moved out of her home in Burnley aged 92.
She said Cleveleys Park was a "very homely place" where all her needs were taken care of.
"It's been very hard," she added. "The fire, the burns, the smoke inhalation didn't kill her straight away, she lived for 30 hours.
"But we couldn't stroke her, hold her hand or hug her. All we could do was touch her cheek and let her know we were there for her.
"Whoever deliberately went in and murdered my mother needs help. It isn't so much punishment, it's help they need.
"This person might get depressed or bored, they might think they can do it again and someone else's family might have to suffer like we are."
Det Ch Insp Andrea Bradbury, who is leading the investigation, said: "This is a difficult investigation in which a fire was deliberately started within a small rest home but there are people out there that will know what happened that night and the person or persons responsible for Edith's death."
