Channel 4 explores The Mystery Of The Man On The Moor tonight at 10PM in a special documentary.
It was a mysterious death that gained worldwide attention for more than a year before finally being solved in January of 2017.
The Mystery Of The Man On The Moor started on a cold dark December day in 2015 when a tall grey-haired man entered a London train station, bought a return ticket to Manchester and never came back.
The following day his body was found on Saddleworth Moor, near Oldham. He was poorly dressed for the weather and carried few clues to identify him - no phone, no wallet, no passport or driving licence.
Apparently killed by poisoning, for 12 months his identity and how he had got there remained a mystery.
With exclusive access to the year-long investigation by detectives from Greater Manchester Police, Mystery of the Man on the Moor on Channel 4 tonight tells the remarkable story of their painstaking work to identify him and to understand his lonely death.
The film features previously unseen footage of the key moments of discovery, as well as moving interviews with the man's family and former girlfriend who, despite extensive media coverage at home and abroad, had no idea he was missing.
The Mystery Of The Man On The Moor airs tonight at 10PM on Channel 4.
