Pedophile teacher abused dozens as clues missed


William Vahey was a beloved teacher in the small world of international schools that serve children of diplomats, well-off American expatriates and local elites. He was often the first to arrive, and the last to leave. He led students on class trips to exotic places.

That was Vahey’s public persona, carefully crafted over four decades until a maid found a trove of photographs showing the model teacher had molested scores of adolescent boys in a career spanning 10 schools on four continents.

The FBI regards Vahey as one of the most prolific pedophiles in memory. And his case has set off a crisis in the close-knit community of international schools, where horrified parents are being told their children may have been victims, and administrators are scurrying to close teacher-vetting loopholes.
