Douglas McCain, Chicago-born ISIS fighter, killed in Syria

CHICAGO (WLS) -- A man born in Chicago was linked to ISIS after being killed while fighting alongside the terror group. Those who know Douglas McArthur McCain say they're stunned.

McCain was one of two Americans killed in Syria in the last few days while fighting for ISIS. According to family members, the state department called his mom over the weekend to inform her that her son had been killed in Syria.

He had an all-American name, Douglas McArthur McCain, and on his Facebook page, his likes included pizza, the Koran and the Chicago Bulls.

Mccain was born in Chicago and lived in the Robert Taylor Homes before moving to Minneapolis with his family as a child. He was a 1999 graduate of Robbinsdale Cooper High School then moved to San Diego where he attended community college.

According to family members, the 33-year-old was raised Christian but converted to Islam.

Earlier this year McCain posted a Twitter message encouraging his ISIS warriors saying "stand strong we will so be 1." His cousin said she thinks he may have lost his way.

"I felt like he may have lost his identity because all of this is not him," said Kenyatta McCain.

In 2003 Minneapolis police said McCain was charged with possession of marijuana and driving on suspended license. His uncle told the Minneapolis Star-Tribune the last time they saw him was several months ago and he told them he was traveling to Turkey.

An estimated 100 Americans have been recruited to fight for jihadists groups in Syria including ISIS, a group U.S. officials call the gravest of threats. It was an ISIS fighter who beheaded American journalist James Foley.

State department officials confirm that McCain was on the terror watch list.

On Tuesday, his sister posted a message of grief on her Facebook page that says, in part, "I never thought this will be the way we say goodbye, this is absolutely unreal to me, I love you big brother."
