The mother of a Charlotte man killed by a drone strike in Yemen last September is suing senior national security officials for the wrongful-death of her son. Samir Khan was a naturalized U.S. citizen born in Saudi Arabia. While attending CPCC in 2004, he created a radical blog that got the government's attention. In 2009, Khan moved to Yemen to produce an English language online magazine for al-Qaida with articles such as "How to Build a Bomb in the Kitchen of Your Mom." Khan was 25 when he died in the U.S. drone strike allegedly aimed at radical Muslim cleric Anwar al-Awlaki, who was also an American citizen. Khan's family condemned the killing as an "assassination." The lawsuit filed Wednesday claims four top security officials violated Khan's fundamental right as a U.S citizen "not to be deprived of life without due process of law."
