SAN DIEGO (CBS SF) — A U.S. citizen from California was killed over the weekend in Syria while fighting for the extremist group Islamic State of Iraq and al-Sham, also known as ISIS or ISIL.
NBC News reported the man is 33-year-old Douglas McAuthur McCain, who died in a battle between ISIS and another extremist group in Syria.
U.S. officials learned of McCain’s death because he was carrying a U.S. passport and $800 in cash, according to NBC News.
His most recent Twitter activity shows a number of tweets and retweets in support of ISIS and jihadist fighters.
On Facebook, McCain posted a series of photos showing the black flag of ISIS and listed his current city as San Diego and that he attended San Diego City College.
McCain was born in Illinois and moved later with his family to Minnesota’s Twin Cities area, according to NBC News. It was unclear when he moved to California.
Last week, State Department spokeswoman Marie Harf said its believed ‘a small number of Americans’ are among the approximately 12,000 foreign fighters in Syria since the beginning of the country’s civil war three years ago.
Another US official, speaking on condition of anonymity, told Agence France-Presse that more than 100 U.S. citizens have traveled or tried to travel to Syria to join the conflict.
