The detention hearing for a Virginia man accused of trying to join a Somali terror group linked to Al Qaeda was postponed until Monday.
Zachary Adam Chesser, 20, of Oakton, Va., faces charges that he provided material support to Al-Shabab, the Somalia-based terror organization that claimed responsibility for the bombing that killed 74 people in Uganda during the World Cup earlier this month. He faces up to 15 years in prison if convicted.
Chesser allegedly tried to travel to Somalia to join Al-Shabab as a "foreign fighter." In July 2008, the affidavit says, he became interested in Islam and, while learning about the religion, became "very 'extremist' in his beliefs."
"He explained that he was watching online videos, discussions and debates, and over-the-counter CDs almost obsessively," the affidavit continues. "One of the authors and presenters he preferred was Anwar al-Awlaki. Awlaki is an American-born and English-speaking American citizen who formerly was an Imam at the Dar al-Hijra mosque in Northern Virginia. Various Islamic terrorists were in contact with Awlaki before engaging in terrorist acts."
Earlier this week, Awlaki was designated by the U.S. Treasury Department as a "specially designated global terrorist."
In April, FoxNews.com spoke to Chesser after he posted a warning on RevolutionMuslim.com following the 200th episode of "South Park," which included a caricature of the Prophet Muhammad disguised in a bear suit. The young man, who just two years ago was studying foreign languages at George Mason University, wrote on the site that Trey Parker and Matt Stone, the cartoon's creators, "will probably end up" like Theo van Gogh, a Dutch filmmaker who was murdered in 2004 after making a film critical of Islamic society.
"It's not a threat, but it really is a likely outcome," Chesser told FoxNews.com. "They're going to be basically on a list in the back of the minds of a large number of Muslims. It's just the reality."
Chesser has not been charged in connection to the online posting.
Chesser's father, David, said he was unaware of the arrest and declined further comment when reached on Wednesday. Chesser's mother, Barbara, reached at her office in Washington, also declined comment Wednesday.
Dean Boyd, a spokesman for the Department of Justice, declined to comment on whether any other individuals may or may not be under investigation in connection to Chesser.
