How Zachary Adam Chesser, who grew up in suburban Fairfax County, played football and rowed crew at his High School, came to espouse a fundamentalist Islamic ideology is not yet clear, but he was so greatly offended at an episode of South Park that supposedly showed Muhammad in a bear costume ( turns out it's really Santa in the bear costume ) that he issued "warnings" on his website.
Chesser came to the attention of authorities when he attempted to board a flight to Uganda July 10. He admitted that he was on his way to try to join an al-Shabab training camp.
Note to parents : if your teen is offended by South Park, it's time to worry.
