Child Predator: Husband And 'Popular Teacher'
Updated: 11:44am UK, Thursday 24 April 2014
The serial child predator at the centre of an FBI investigation had a wife and two adult children and was a popular teacher among his students, officials have said.
William James Vahey travelled the world for four decades before his suicide in a Minnesota motel last March.
While teaching, he also served as coach on various school sports teams.
The FBI said he was a "popular and highly respected teacher".
"He had access to children because of his position of trust," said FBI special agent Patrick Fransen.
"He created a system that gave him the opportunity and the means to molest children."
The FBI says he may have carried out child molestation on an unprecedented scale, often drugging his victims.
Vahey told investigators he suffered molestation as a child and went on to prey on boys.
The New York native graduated from California State University, Long Beach, with a Bachelor of Arts in political science, according to a resume cited by the FBI.
He received a master's degree in curriculum development from Goddard College in Plainfield, Vermont.
At the time of his death, he was 64, approximately 6ft (182cm) tall, and weighed about 190 pounds (86kg).
He was teaching ninth-grade world history and geography at the American Nicaraguan School in Managua.
Vahey maintained two residences, one in London, where he had taught at an elite school, and another on Hilton Head Island, South Carolina, the FBI said.
In 1969, Vahey was arrested in California on six counts of child molestation.
He pled guilty to one count of child molestation and was sentenced to 90 days in jail, followed by five years' probation.
The conviction required Vahey to register with California's sex offender registry for the rest of his life.
However, Vahey eluded that requirement.
Officials said he had not renewed his registration as a sex offender since 1970. He went on to pursue his teaching career in Nicaragua, the UK, Venezuela, Indonesia, Saudi Arabia, Greece, Iran, Spain, and Lebanon.
His victims are believed to be multinational as many of those schools were attended by the children of American diplomats or military personnel stationed overseas.
Vahey coached boys on middle school, varsity boys' basketball, softball, flag football, and soccer, among other things.
He also served as activities director, student council adviser, cooking club adviser and forensics adviser.
He often accompanied students on cultural studies or sports trips, the FBI said.
Vahey killed himself two days after agents in Houston sought a warrant to search a computer thumb drive belonging to him.
