Al Qaeda Spokesman Adam Gadahn Was Once American Adam Pearlman

Former California suburbanite was killed in an al Qaeda counterterrorism raid.

A former resident of Orange County, California, he started appearing in a series of videotaped segments broadcast in October 2004, the FBI said. In a 2004 video, he said, “The streets of America shall run red with blood.”

"I discovered the beliefs and practices of this religion fit my personal theology and intellect as well as basic human logic," he wrote at the time. "Islam presents God not as an anthropomorphic being but as an entity beyond human comprehension, transcendent of man, independent and undivided."

The son of musician Phil Pearlman, Gadahn was raised in Orange County on a goat farm. He was home-schooled until the age of 15, at which point he moved in with his grandparents in Santa Ana, California, ABC News reported in 2004.

His aunt, Nancy Pearlman, told ABC News in 2004 that Gadahn was a typical teenager with shifting interests.

"Adam was a very loving, caring, intelligent young man," she said. "He was listening to hard rock music. He gave that up when he got religious."

Diab’s ex-wife told ABC News' Brian Ross in 2004 that Gadahn was "fresh meat.”

Gadahn was "someone they could control," Saraah Olson, Diab’s ex-wife said. "Not only that, he's very unassuming-looking, he can do a lot of their tasks.”

Gadahn once tore up his U.S. passport on camera and regularly produced videos in English and Arabic.

"America is absolutely awash with easily obtainable firearms," Gadahn said in a 2011 al Qaeda video urging individual violent jihad. "So what are you waiting for?"

In October 2012, Gadahn urged al Qaeda’s followers to attack the satirical French newspaper Charlie Hebdo.

A family member declined to comment to ABC News.
