In January 2012, ABC News announced that environmental activist Erin Brockovich has launched her own investigation into the mysterious illness causing facial tics and verbal outbursts among 15 teenagers in Le Roy, New York State.
Most of the teens have been diagnosed with conversion disorder - a psychological condition that causes physical symptoms like jerky tics, convulsions and even paralysis.
Brockovich suspects groundwater contamination from a chemical spill from more than 40 years ago may be behind the Tourette-like symptoms.
"They have not ruled everything out yet," Brockovich told USA Today. "The community asked us to help, and this is what we do."
“If you follow your heart, if you listen to your gut, and if you extend your hand to help another, not for any agenda, but for the sake of humanity, you are going to find the truth.” Erin Brokovich
