A PLAQUE which has appeared on a Prestatyn hillside is the latest puzzling episode in one of North Wales's most mysterious cases.
It is now 32 years after Trevaline Evans left her antiques shop in Llangollen, never to return, and the case still baffles police and the community.
Various theories have been proposed but one in particular keeps being raised - and the plaque is the latest tantalising hint.
Within the past two weeks, the metal plate has been attached to a wooden bench at Pant-y-Fachwen, the remains of a 200-year-old miner's cottage on the hillside above Prestatyn.
The site, just off the Offa's Dyke footpath, is a popular resting spot for walkers.

The inscription scrawled on the plaque reads: "Justice awaits those responsible for the removal and disposal of Trevaline Evans (in this life or next) from Rhuddlan Golf Club on March 19, 2019 at noon.
“May the Lord have mercy upon their soul."
The style is identical to that of a plaque which was fixed last year to a bench on the Prestatyn-Dyserth walkway and later removed by Denbighshire County Council.
That read: "In memory of Trevaline Evans. Vanished June 16, 1990, found in Rhuddlan Golf Club March 14, 2019, removed March 19, 2019. RIP.”
Mrs Evans, who was 52 when she vanished, was not known to have any connections with Prestatyn or Dyserth
But she and her husband Richard were refurbishing a bungalow in Rhuddlan where they planned to retire.
Mr Evans, who has since died, was arrested at one stage but later released without charge.
News of the latest plaque came as a surprise to brothers Andrew and Lee Sutton, who remain convinced that she was buried under the floor at the golf club, where Mr Evans had apparently been working.
On March 14, 2019, having been tipped off by an unnamed person that there were human remains at the clubhouse, they hired a special camera which, they say, clearly showed skeletal remains including a hand and skull.
They told the police, who carried out their own search five days later but found nothing.
Lee, from Kinmel Bay, and his brother, who now lives in Milton Keynes, say that the photographic evidence was confirmed by a forensic expert and that they still retain those pictures.
"We have no axe to grind in this at all but we know what we saw - and what we saw had been removed by the time the police went to the golf club," said Andrew.
They complained to the Independent Office for Police Conduct about the police handling of the case, but the matter was referred back for North Wales Police to investigate, and the complaint was rejected.
Neither of them has any idea who is responsible for the plaques or why they have been placed in such unexpected locations but since revealing their findings a window in Andrew's house has been smashed and Lee has received threatening phone calls.
"It could be someone with a guilty conscience responsible for the plaque: the details on it are quite correct," said Lee.
Andrew added: "Clearly someone is uncomfortable with what happened."
The brothers have been told that a vigil was held on the walkway last year before the plaque was removed, but don't know who attended or organised it.
The disappearance of Trevaline Evans, which was featured on BBC's Crimewatch at the time, is to be the subject of an episode of Channel 4's "In the Footsteps of Killers" which investigates cold cases.
Co-presenters Emilia Fox and Professor David Wilson were seen filming in Llangollen in February.
