Tre Von Harris, 19, was recently indicted by a federal grand jury in Austin on two counts of sexual exploitation of children and one count of interstate communication of a threat/extortion.

Sextortion is a form of online blackmail that involves a victim being threatened or coerced into sending money or explicit images online.

It's a form of online blackmailing that's taken hold of children across the nation, including San Antonio. Sextortion has become such an enormous problem, the FBI is on a mission to warn the public and teach parents what to look for.
