The clues that led to the unmasking of Jihadi John came in fragments.

Former hostages said that the Islamic State killer spoke fluent Arabic, a hint that he was not from Britain's large Pakistani or Bangladeshi communities. He made his captives watch online videos from al-Shabaab, the Somali terror group, which suggested he may have had an interest in jihad in east Africa before heading to Syria.
