Barbara Ochoa
Barbara W. Ochoa (stage name Petra Luna) is a struggling American vocal artist, known mainly for basing her musical career around a pious, self-declared "war on [sexual] abuse". Most of Ochoa's public-relations activity is conducted through the social networking website, MySpace - where thanks to a zealous and insistent fan base, her material and anti-abuse campaigns are given some recognition and respect. Within this on-line world, Ochoa uses image manipulation to construct herself as a fantastical, winged, cult-figure; an empowerer and warrior against child abuse. She sometimes publishes videos on YouTube, injecting herself in to a graphically-enhanced, newsroom-type setting, and making emotional pronouncements on familiar, sexual-abuse related subjects.

Ochoa's performance on 20/20 is likely to alienate her from any producer who is sympathetic to her stated aims. It is perhaps likely, that the producers of 20/20 selected her case because they were aware - from her performances on-line - of her poor judgement and general incompetence in front of a camera.
