	Horner died on 11 March 2014 following a gunshot to the head while outside of a previously attacked restaurant in Kabul. Horner was there to follow up on a terrorist attack the restaurant had suffered two months prior. While on his way to investigate the story, two men shot Horner execution style in the middle of a street in the Wazir Akbar Khan, Kabul district. A division of the Taliban, Fidai Mahaz, claimed the murder citing the theory that Horner was a British spy; however, it is unclear whether these claims are factual or not. The two suspects were caught on video fleeing the area; however, no arrests were made in connection to the murder.
