An international school that hired a teacher believed to be one of the most prolific pedophiles in memory says its director has resigned.

The American Nicaraguan School said in an email to parents and staff Tuesday that Gloria Doll had resigned, effective next month.

In March, a maid working for the school brought Doll a memory drive containing lewd images of drugged male students taken by William Vahey during previous jobs in London and Venezuela. Doll fired Vahey, who flew back to the U.S. and killed himself. She was criticized by parents and commentators in Nicaragua for not telling local police before he left the country.

Doll and school administrators did not respond to emailed requests for comment.
