No family, friends or loved ones came forward when the lifeless bodies of these six people were found in waters.
Their identities remain a mystery, what led them to their deaths remains unknown and their life's achievements remain untold.
However the UK Missing Persons Unit continues to appeal for any information for these six people, who deserve to be recognised.
Due to the circumstances in which they were found there are cases in which there are only a few identifying features left by which they could be recognised.
In other cases there are distinguishing features including what they were wearing that could spark memories.
Here we take a look at the cases of six men who remain unidentified.
