This is the longest unsolved murder case in the recent history of the London Metropolitan Police.
Twenty years ago, a young African boy was murdered in a horrific manner. His head, legs and arms were severed and his body was dumped in the River Thames.
His identity remained a mystery, but investigators called him "Adam."
There have been several arrests over the years, many forensic investigations, but no one has been charged with murder.
I have watched this case from the beginning, I even went there to find out the truth about what is generally believed to be the birthplace of the child. Twenty years later, I am now talking to people who have been closely associated with this case. Some people are talking for the first time.
And we also visited Adam's unmarked grave in a large cemetery in south London.
A passerby was the first to see the body.
Eden Munter was crossing the Tower Bridge in central London at the time. He had to arrive at a business meeting.
It was only 10 days after the 9/11 attacks in the United States and the city was still shrouded in mysterious silence.
"The waves were high at that time," Eden recalls. I thought it was a tailor's slim. '
They don't talk much about the case.
"Then it came under the floating bridge and then I looked at it carefully, that is, the marks of the body and the wounds on it."
Police pulled the body out of the water near the Globe Theater upstream.
This is the memory that Eden still lives with today.
"I still think about it. I will never forget it as long as I live. '
