A 30-year-old former school teacher who allegedly produced child pornography has replaced former Al Qaeda chief Usama bin Laden on the FBI's "Ten Most Wanted Fugitives" list.

Eric Justin Toth, who has used the alias "David Bussone," is wanted for his alleged production and possession of child pornography in Washington, D.C., and Maryland, authorities said Tuesday. A $100,000 reward is being offered for information leading directly to his arrest.

The investigation into Toth began in 2008 when pornographic images of children were allegedly found on a school camera that was in his possession.

The FBI said in a press release that Toth, a former private school teacher and camp counselor, has eluded authorities and is believed to have traveled to various states since 2008, including Illinois, Indiana, Wisconsin, Minnesota. He is also suspected of living in Arizona in 2009.

The fugitive, whom investigators describe as a "computer expert," may be advertising online as a tutor or male nanny, authorities said.

"He has the ability to integrate into various socio-economic classes, and is an expert at social engineering," the FBI said. "Toth possesses an educational background conducive to gaining employment in fields having a connection to children."

Toth is described as 6 feet, 3 inches tall and weighing 155 pounds. He has brown hair and green eyes and a medium complexion. He also has a mole under his left eye.
