THE skeletal remains of a man found in woodland and the body of a man with hypothermia found in a river are among the cases of unidentified bodies found in North Wales that remain unsolved.

Dating back to the 1970s up until the most recent in 2015, there are 15 open cases of missing persons in the the North Wales Police region listed by the UK Missing Persons Bureau.

The UK Missing Persons Unit uses its website, social media, a weekly podcast, and other means to raise awareness when someone goes missing.

The body of a man was found in Clocaenog Forest in 2015

They also have a list of historic cases that remain unsolved in the hope that someone will come forward with information to put a name to unidentified bodies, even if it is years or even decades later.

As would be expected, many of the bodies were found washed ashore on North Wales beaches or recovered from the sea.

But others include the discovery of a man buried in a shallow grave in Ruthin and a man found hanging in woodland in Bangor.

The skeletal remains of a male were discovered at Clocaenog Forest, and it is believed the body has been at the location for a number of years. In life he would have been 173cm - 180cm (5 Ft 8 Ins - 5 Ft 10 Ins) tall with a stocky build.

He is thought to have been over 54 years of age at the time of his death, most likely in his 60s, and was born before 1950. Dentistry shows work typical of that carried out in the UK between 1980 and 2000.

He suffered from athritis and an inflammatory joint condition, which would have affected his back and a number of other joints. This would likely have given him pain and reduced movement. He had previously suffered an injury to his spine, a broken nose and possibly an injury to his left wrist.

A badly decomposed pair of Marks and Spencer underpants and dark green Pringle jumper were recovered close to the remains. They may have belonged to the individual, although this cannot be confirmed.
