Social workers could have stopped the abuse suffered by a disabled woman before she was murdered by her sister, a review has found.

Sharon Greenop's body was found in her house in Troon, South Ayrshire, during 2016. The 46-year-old suffered a series of injuries including multiple rib fractures.

A court later heard she had been abused over a seven-year period before her death.

Last May, her sister Lynette, 41, was jailed for a minimum of 23 years after being found guilty of murder.

Sharon's daughter Shayla, 21, was found not proven after also being accused of her murder.

On Wednesday, the results of a significant case review were published by South Ayrshire Council, which apologised for "failing Sharon".

It found that a decision to end Sharon's care package was "flawed" and "allowed the circumstances to develop that ultimately led to her death".

Opportunities were missed to raise concerns about her wellbeing, which could have resulted in interventions to stop her being abused, the review found.

However, the review made clear that the responsibility for Sharon's death lay with Lynette and that "no-one could have foreseen her violent death".

Her care package was one of hundreds in South Ayrshire which hadn't been reviewed for a number of years and poor record-keeping meant it was "difficult to manage her case effectively", it added.

Professor Paul Martin, chair of the South Ayrshire Adult Protection Committee, said: "Sharon's violent death was a tragedy that no-one could have foreseen and our thoughts are with her family and friends.

"It's clear that steps could have - and should have - been taken by the South Ayrshire Health and Social Care Partnership that could have stopped the abuse suffered before her untimely death."

Tim Eltringham, director of the health and social care partnership, added: "While we know it won't bring Sharon back, we are deeply sorry that we failed Sharon and her family and I have delivered that apology in person to her sister, Diane Hogg."

In statement, Ms Hogg said: "It's been two-and-a-half years since the brutal murder of my sister Sharon Greenop at the hands of her younger sibling Lynette, a year since the trial and conviction of her murderer.

"I questioned the continuity of care and the system which should have protected Sharon. As the review was progressing and urgent recommendations were being administered, I knew that other areas would take time to change.

"So, with hindsight maybe understanding and insight, looking at the past mistakes it could prevent another family from undergoing the same traumatic experience. Hopefully these lessons can and will be learned.

"Although I have answers it still leaves an undeniable feeling within myself that just maybe my sister would still be alive if protocols and policies had been followed."

A trial last year heard how Sharon was assaulted on various occasions by her sister between November 2009 and September 2016.

She was repeatedly struck with "object or objects" and had her neck compressed.

After Sharon's death, Lynette failed to obtain medical help and then posed as her dead sister to steal money from her bank account.

She went to a music gig with niece Shayla, with claims she introduced her aunt as "mum".

Sharon's corpse was only found in November 2016 when a next door neighbour reported a foul stench in his home.

The review was led by experienced social worker David Crawford and involved the council, NHS Ayrshire & Arran and Police Scotland.
