MINNEAPOLIS (WACH/AP) -- The FBI is asking for help to identify at least 90 victims of a suspected serial child predator who they say maintained a home in Hilton Head Island.
Federal investigators say the suspect, 64-year-old William James Vahey, killed himself in Luverne, Minn., on March 21.
The FBI reports that Vahey worked in American schools worldwide for four decades
FBI agents in Houston filed for a warrant March 19 to search a computer thumb drive that belonged to Vahey, a U.S. citizen.
An employee of an American school in Nicaragua where Vahey had recently taught ninth-grade world history and geography gave the drive to the U.S. Embassy.
Special Agent Shauna Dunlap says the thumb drive contains pornographic images of at least 90 boys, aged 12-14, who agents suspect were Vahey's students starting in 2008.
Vahey, who maintained residences in London and Hilton Head Island, SC, traveled extensively and internationally during the past four decades, working as a middle school and high school teacher at several American international schools in at least nine different countries.
He taught history, geography, and social studies, and also coached junior varsity and basketball teams for boys.
The FBI says Vahey regularly accompanied students on overnight field trips.
According to Investigators Vahey was employed at the following schools between 1972 and 2014.
American Nicaraguan School, Managua, Nicaragua: 2013 until March 2014;
