A mum drowned and burned her four-year-old daughter before claiming ‘angels’ had taken her.

Carly Ann Harris killed her daughter Amelia Brooke Harris after suffering a serious mental breakdown which made her believe she was saving the world.

There is no dispute that Harris, 38, killed Amelia at their home in south Wales - but the mum was today acquitted of murder by reason of insanity.

Psychiatrists agreed she was suffering from paranoid schizophrenia and she has now been detained indefinitely at a psychiatric hospital by a judge at Newport Crown Court.

Amelia's teenage brother found her body, wrapped in a sheet, on a table in their garden in Trealaw, South Wales, on June 8 this year.

Neighbours heard screaming and, when they went into the street to see what was wrong, they found Harris's older children visibly distressed.

One neighbour Megan Griffiths saw Harris standing in the front garden looking "dazed", the court heard.

The defendant told her: "God will be with her. The angels have taken her."

Ms Griffiths dialled 999 and went into the back garden of Harris's house where she saw Amelia's charred remains lying on the coffee table covered with a sheet.

When the police arrived at the scene, Harris told them: "The angels told me to do it. Just arrest me. It's OK."

The court heard how one of Harris's two sons said his mother had "not been well" for some six weeks before the incident.

Amelia had died from drowning and was already dead when she was set on fire, according to Home Office pathologist Dr Richard Jones.

Harris had been taking "small amounts" of amphetamines leading up to the incident, but experts agreed she had not been suffering from drug-induced psychosis.

Dr Arden Tomison, a psychiatrist, diagnosed Harris with schizophrenia and said at the time she was suffering from an "abnormality of mental function which substantially impaired her ability to form a rational judgment".

He said she appeared to have experienced "paranoid and religious delusions" and believed she had to kill Amelia to save the world, and was being tested by God who would then return her daughter to her.

Dr Tomison said that when he examined Harris as recently as a month ago, she was still firm in the belief that she had to kill her child in order to protect her and save the world.

Another psychiatrist, Dr Phillip Joseph, agreed Harris had suffered from schizophrenia following a urinary tract infection in 2014.

Harris denied murder and manslaughter and jurors took an hour to find her not guilty of murder by reason of insanity.

Mr Justice Picken said he was imposing a hospital order and restriction order without limit of time.

"This is a deeply sad case in circumstances where you have killed your four-year-old daughter Amelia at your house which you shared with her," the judge said.

"These facts speak for themselves. A young girl rich in promise met her death at the hands of her own mother in the most horrific manner."

Speaking outside court, Harris's mother Jacquie Harris, who was visibly upset, said: "It's bittersweet... I am devastated and beyond words.

"I lost Amelia and I lost Carly and the two boys lost their mother and sister and each other.

"I have lost my life. I've gone beyond tears. She is my daughter and I am devastated and I have lost my daughter."

Mrs Harris added: "She is not a monster. She is the salt of the earth."
