So says CBS [1]:
After a three-year hunt involving investigators across the U.S. and Canada, a young girl who was featured on the Internet in a series of sexually explicit photographs has been found and is safe, police say.
The girl is nearly a teenager now and lives with a foster family, police add.
Her adoptive father, who apparently took the pictures, is in prison for trading pornography online, according to police.
Hmmm.
How to ID such a person, I wonder?
