The FBI said last month that William Vahey had molested at least 90 boys, whose photos were found on a memory drive stolen by his maid.
The bureau said Tuesday that it has now "been contacted by several hundred individuals from around the globe."
Vahey killed himself at age 64 after evidence of child molestation was found on one of his memory drives.
This combination of photos provided by the Federal Bureau of Investigation shows William James Vahey in 1986, 1995, 2004 and 2013. |
