Regardless of forensic exams, intensive inquiries and searches and appeals for info, detectives nonetheless haven’t solved the thriller of the person within the wetsuit.
He was discovered simply earlier than 08:30 on a Friday morning final October within the eerily nonetheless rolling mid-Wales countryside.
Investigators suspect he might need been within the huge Claerwen Reservoir for as much as 12 weeks – so may have been within the water since way back to July and within the top of summer time.
What police learn about ‘uncommon’ loss of life
What police say is “extremely uncommon” concerning the man within the wetsuit is that no proof of his private belongings or an deserted automobile or bike had been ever found.
However with no garments or car discovered and the closest bus cease about 4 hours’ stroll away, police do suppose it’s unlikely he walked there in his wetsuit.
When emergency crews recovered the physique, it was extremely decomposed and brought to a close-by morgue for examination. Fingerprint and DNA exams failed to search out any matches.

It was a blustery February day after we travelled alongside the one monitor lane to the highest of the reservoir’s imposing 183ft (56m) dam.
Mist lined the encircling Powys panorama and there have been no birds or different indicators of life, past a couple of sheep dotted throughout the naked hills that belong to a distant farm above.
