A NUMBER of grim and as yet unexplained discoveries have been made across North Wales over the last few decades.
Here are some of those cases and where to go if you think you can help police to solve them.
In November of 2015, the skeletal remains of a man were found at Clocaenog Forest, near Corwen.
Police believe his body had been at the location for a number of years.
The man is believed 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, and he suffered from both arthritis and an inflammatory joint condition - which 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.
