Public asked to help with investigation after postmortem examination in October failed to find any DNA
He was wearing a wetsuit when police found his body floating in a Welsh reservoir in October. No clothes or belongings were discovered on the shoreline, and no car or bicycle was found nearby, despite it being a seven-mile hike to the nearest bus stop.
A postmortem examination failed to find any DNA or fingerprint matches and two police appeals for information about the man were unsuccessful.
