A post-mortem has failed to establish how missing US tourist Susan McLean died.
The 61-year-old, from Pennsylvania, disappeared while holidaying in Aberfeldy in May.
Her body was discovered in woodland by a volunteer search party nearly three months later.
But the cause of her death may never been known, after an examination by pathologists proved inconclusive.
Her death certificate lists the reason for her death as “unascertained” and notes “Putrefied body.”
Police said her death is not being treated as suspicious and it is believed Susan took her own life.
Her friend Lorna VanderZanden, who jetted into Scotland to reignite the search, said she was “astonished” that her volunteer party had found the body after two separate days of hunting, while police had drawn a blank.
