Zachary Adam Chesser

Zachary Adam Chesser (born December 22, 1989) is an American convicted in 2010 for aiding al-Shabaab, which is aligned with al-Qaeda, and has been designated a terrorist organization by the U.S. government.

He was referring to the 2004 murder of a Dutch filmmaker, Theo van Gogh, by a Muslim extremist.

He graduated from Oakton High School in 2008.

Chesser was known as an athlete, participating in the Oakton's football, basketball and crew teams.

His yearbook profile said: "As the only Caucasian member of the break-dancing club, senior Chesser was not intimidated by being the only non-Asian."

After high school, in 2008, Chesser enrolled at George Mason University in Fairfax County, Virginia, dropping out after one semester.

Chesser told Federal Bureau of Investigation agents he became interested in Islam in July 2008.

High school friends said his interest seemed to start when he began dating a Muslim girl.

Sources disagree about whether he converted.

Chesser used online media to disseminate his views, catching the attention of Jarret Brachman, a terrorism scholar, who engaged Chesser in email correspondence.

In his 2008 book on terrorism, Brachman had coined the term "jihobbyist" for people such as Chesser, who are fascinated by Islam or jihad but were not members of recognized terrorist organizations.

In 2009, he married Proscovia Nzabanita, a Ugandan Muslim woman, and they had a son, Talhah.

(Nzabanita's mother Cecilia is not Muslim.) Since Chesser's incarceration, his mother Barbara and Barbara's life partner Stacy Anderson, also a lawyer, have had custody of his son against Chesser and Nzabanita's wishes.

His wife Nzabanita was deported from the United States.

He worked briefly as a caretaker at the Islamic Center of Northern Virginia in Fairfax.

In 2009, both friends and members of the Islamic Center of Northern Virginia noticed that Chesser's views were becoming more extreme; he had conservative ideas about dress customs.

An older member at the Islamic Center said he tried to broaden Chesser's views of the Islamic scriptures, and that Chesser took too narrow a view.

This was one of the few American websites to praise the 2009 Fort Hood Shooting, in which a US Army psychiatrist killed fellow soldiers.

By 2010, Chesser had created a YouTube account called LearnTeachFightDie, and a website called the mujhidblog.com.

He had e-mail correspondence with Anwar al-Awlaki, a radical American Muslim cleric hiding in Yemen.

United States officials have alleged that the latter has encouraged homegrown terrorism.

Al-Awlaki was later targeted and killed in a drone strike because of his role in al-Qaeda attacks against the United States.

In April 2010, Chesser wrote an e-mail to FoxNews.com, saying that he sought to "raise awareness of the correct understanding of key Islamic beliefs".

He said "If you kill us, then we kill you", and he quoted al-Qaeda leader Osama bin Laden, saying that Muslims had the freedom to act against attacks on the Prophet.

He further wrote in the e-mail:

"I seek to help the world understand that neither the Muslims in general nor the mujahideen including Al Qaeda are abject to peace, but that this peace come with the following conditions: a complete withdrawal of non-Muslim forces from Muslim lands, an ending of the propping up of the apartheid regime of Israel, and a ceasing of the propping up of the brutal dictators we currently have who refuse to rule by divine law. ... I also seek to help the world understand that there will be no peace until the above conditions are met. Basically the formula works like this … if you kill us, then we kill you. If you do not kill us then we can have peace. 9/11 had nothing to with freedom or democracy. It had to do with the murder of hundreds of thousands of Muslims around the world by American and other powers. ... As Usama bin Laden said with regard to the cartoons of Denmark, if there is no check in the freedom of your words, then let your hearts be open to the freedom of our actions."

Chesser became one of the most visible members helping the American Jesse Curtis Morton, aka Younes Abdullah Mohammed, run the radical Revolution Muslim website.

Morton has said he created the site to promote propaganda supporting al-Qaeda.

In April 2010, Revolution Muslim's website posted a statement jointly drafted by Chesser (under the online username Abu Talhah al-Amrikee) and Morton that warned South Park creators Trey Parker and Matt Stone of violent retribution for their depictions of Muhammad.

The post included the business addresses of likely targets of retribution, including Comedy Central and Parker and Stone's production company.

Chesser threatened the South Park creators on a variety of other online platforms, including his blog and Twitter pages.

Chesser wrote, "We have to warn Matt and Trey that what they are doing is stupid and they will probably wind up like Theo van Gogh if they do air this show."

On July 10, 2010, Chesser was arrested with his infant son while boarding a flight to Somalia via Uganda.

He told federal agents that he intended to go to Somalia, home of al-Shabaab, a terrorist organization.

After pleading guilty, Chesser was sentenced in federal court on February 24, 2011, to 25 years in prison.

He is also known for his alleged threats to South Park creators Trey Parker and Matt Stone for depicting Muhammad in an episode of that series.

Chesser was born in Charlottesville, Virginia to Barbara Katenbrink Chesser, a lawyer and prosecutor, and David Chesser.

His parents divorced.

Chesser moved to Fairfax County, Northern Virginia by the time he was in middle school.

He was selected for the Gifted and Talented program at Kilmer Middle School.
