Joanne Hussey, 33, had admitted killing 76-year-old Annie Garbutt but denied murder, claiming voices in her head told her to do it.

A jury at Leeds Crown Court took just one hour to find her guilty of the "brutal" murder at Mrs Garbutt's home in Mirfield, West Yorkshire.

Hussey, from Yeadon, Leeds, had admitted manslaughter on the grounds of diminished responsibility.

The court heard how Hussey beat her grandmother over the head and left her lying in pools of blood on her bed on May 7 last year.

Hussey had been worried about the financial implications of Mrs Garbutt, an Alzheimer's sufferer, going into a home, the court heard.

She initially told police that she had found her grandmother dead in her bedroom but later admitted to killing her and said that she suffered from a mental abnormality.

The jury heard how Hussey had told a doctor she had been hearing voices in her head for about two weeks telling her to get rid of "bad people".

Prosecuting, James Goss QC told the court: "The blows were hard ones because the voices told her to do it harder and harder, then they told her to stop."

The jury of seven women and five men delivered a unanimous guilty verdict after a two-week trial.

Hussey, wearing a white shirt and black jacket, hung her head in the dock as Judge Scott Wolstenholme told her to expect a life sentence.

He said: "The jury have found you guilty of murder and you probably know that the sentence for murder is fixed by law.
"The only sentence that can be passed is one of life in prison."

The judge adjourned sentencing until June 11 for psychiatric reports to be prepared.
