The call for answers grows louder in Upstate New York. Why is a cluster of people in the village of Le Roy suffering from uncontrollable tics and verbal outbursts?

Lana Clark`s daughter Lauren is a sophomore at Le Roy Junior/Senior High School. She is one of the 16 known students at the school suffering from the “medical mystery.”

“Your heart just breaks,” Lana said. “It aches. I mean, this is your child. You don't want something like this for your children or even anybody else's children.”

Lana added, “She was scared. I was scared. She was upset. I mean, there were times that she broke down and started crying, and you know, although, being a parent, I have to be strong. I was ready to go cry, too.”

Charlene Leubner’s daughter, Traci, a junior at the school, suffers from the same medical ailment. Charlene was equally baffled by her daughter`s Tourette-like symptoms and unsatisfied with the diagnosis she received from doctors.

“What's going on?” she asks. “Is this something contagious? What's causing all of these girls at once to come down with the same sort of symptoms?”

As for Traci, who`s gone from the honor roll to failing grades, she just wants to get better.

“I don't want people to see me because everyone stares and says things they shouldn't, and it just makes me want to cry,” she said.

And it's not just the affected families who are suffering. Craig Bower’s daughter attends the school as well, and although she does not suffer from this medical mystery, he admits that he worries all of the time.

“I worry every day," he said. "I'm constantly monitoring her after a nap … I'm [asking], 'Is she OK?’ It is a hell of a way to live.”

Lauren Clark added, “I just want all of us to get better and just, like, I want all of this to stop. I want all of this pain to like go away.”

A new question is being raised: Is gas being extracted using a technique called fracking?

HLN correspondent Jim Spellman talked to HLN’s Dr. Drew Thursday about the six natural gas wells on a school's grounds and the so-called fracking method “where a liquid with water and some potentially very dangerous chemicals is injected into the ground to release the gas.”
