An American man killed in combat in Syria last weekend was a member of Islamic State, the latest evidence of the terrorist group’s ability to recruit lost souls and religious zealots from pretty much anywhere in the world.

The US State Department on Monday informed 33-year old Douglas McArthur McCain’s family that he was apparently a member of IS, and died in combat against the rival Islamist group al Nusra Front, an al Qaeda-linked organization that the US government has blacklisted as a foreign terror organization.

McCain was born in Illinois and with his family moved to the Minneapolis area in Minnesota, where he graduated from high school in 1999.  He later moved to the San Diego area, where he attended community college.  The family was already concerned with McCain’s social media statements of support of the Sunni Muslim militant group Islamic State, which has seized large areas of Iraq and Syria. 

He’s not the first American to go to fight in the Syrian civil war.  In May, an American from Florida conducted a suicide bombing for al Nusra.  A Denver woman was arrested in July on suspicion of trying to fly to Syria to support insurgents.  Two men in Texas were taken into custody on similar charges in June.

US Attorney General Eric Holder says 7,000 foreigners are in it including dozens of Americans.
