The FBI is asking for help to identify potential victims of a suspected child predator who taught at schools across the world for more than four decades.
William James Vahey killed himself in Minnesota last month, two days after a federal judge said authorities could search one of his computer thumb drives.
The FBI said the storage device contained pornographic images of at least 90 boys, ages 12 to 14, who appeared to be drugged and unconscious.
Vahey began teaching in private schools in 1972. He last taught at the American Nicaraguan School in Pista Suburbana, Managua, Nicaragua from August 2013 until March 11, two days before he committed suicide.
When confronted with the images, Vahey confessed to having preyed on boys his entire life.
Prior to his job in Nicaragua, Vahey taught at the Tehran American School in Iran from 1972-73; the American Community School of Beirut, Lebanon, 1973-75; the American School of Madrid, Spain, 1975-76; the Passargad School in Ahwaz, Iran, 1976-78; the American Community School in Athens, Greece, 1978-80; the Saudi Aramco Schools in Dhahran, Saudi Arabia, 1980-92; the Jakarta International School in Indonesia, 1992-2002; the Escuela Campo Alegre in Caracas, Venezuela, 2002-09; and the Southbank International School in London, 2009-2013.
Such schools typically serve a mix of students from those countries, as well as the children of U.S. diplomats, military personnel and U.S. citizens working abroad, and the FBI said it believes his victims are multinational.
