An investigation into the death of a vulnerable woman in Dumfries has found police were initially sent to the wrong house.
Officers mistakenly spoke to an 84-year-old woman at the wrong address and notified the dead woman's family that she was safe.
The body of a 52-year-old woman was found the following day at her home.
The women’s daughter rang the police shortly after 10.00pm on Friday 19 February 2016, as she was concerned about her mother's safety.
A description of the woman and her address were given but police were sent to the wrong house.
She was found dead at approximately 2.40am on 20 February after officers forced entry.
This was around four and a half hours after her daughter initially phoned.
She is suspected to have died from an accidental overdose of prescribed medication.
The Police Investigations and Review Commissioner (Pirc) identified a number of failings, including with the mapping system used by the force.
They concluded it was likely the woman had already died before officers were contacted.
The police didn’t receive any details of the woman's age, physical description or that she was vulnerable.
They went to the wrong address and woke an 84-year-old woman at 10.35pm.
Police failed to notice her name was different to the woman they were looking for.
The family of the woman were told officers had spoken to her and she was safe and well.
The report raised concerns about the mapping system and "failings in the actions of both area control room staff and the attending officers".
The Police Investigations and Review Commissioner says it was "deeply troubling" that the systems issues had not been resolved and "disappointing" the officers had failed to realise the names had not matched up:
Police Scotland has apologised and say it has taken steps to address the issues raised:
The family of the woman have made this statement:
