A computer scientist at a university in the north of England is studying an image of a corpse - attempting to solve a mystery that has gripped the Middle East for nearly 50 years.
'This is what he looks like now?' asks Bradford University's Prof Hassan Ugail doubtfully.
The digitized photo is of a decomposed face and it is about to be run through a special algorithm for our BBC investigation.
The original photo was taken by a journalist who saw the body in a secret mortuary in the Libyan capital in 2011. He was told then that it could be charismatic cleric Musa al-Sadr, who vanished in Libya in 1978.
Sadr's disappearance has spawned endless conspiracy theories. Some believe he was killed, while others claim he is still alive and being held somewhere in Libya.
The sensitivity of our investigation led to our team being detained in Libya for several days, highlighting the emotional and political stakes surrounding Sadr as a revered leader.
The project strives to uncover Sadr's fate, drawing parallels to similar historical events that shaped regional dynamics. As we continue our investigation, the implications of our findings could challenge longstanding beliefs and reshape narratives about this enigmatic figure.
