A federal prosecutor says parents need to know their children’s online friends. Assistant U.S. Attorney Nancy Healey says that includes the people who are on a kid’s smart-phone contact list. Healey says many young people don’t know the people they’re dealing with and might send risque pictures to an adult with no qualms about trying extortion. She says sexting and sextortion are now part of the vocabulary of people who investigate crimes against minors. Healey works out of the U.S. Attorney’s office in the Vinegar Hill federal building. She was a Wednesday guest on Charlottesville Right Now with Les Sinclair.
