It was June the 2nd 1994, a summer’s evening in Kirkwall, Orkney.

Waiter, 26-year-old Bangladeshi national, Shamol Mahmood, clocked in for his second shift that season. Little did he know, that this would be his last night alive.

As Shamol was serving his customers, a masked gunman walked into the restaurant, pointed a pistol at his head and shot him point-blank.

It would take more than a decade to solve this case, which police referred to as the 1000-piece puzzle.

And even after they arrested a man for this senseless crime, the residents of Orkney were still divided: was he really the killer?
