Twin cheerleaders are making disturbing claims against their former coach in a lawsuit, saying that he sexually abused them when they were minors starting at the age of 15. The lawsuit was filed Monday on behalf of 22yearold Jessica and Hannah Gerlacher, who are accusing their excoach Jason McCartney, who worked with nationallevel athletes at the Frisco and Plano gyms, of “repeatedly engaging in inappropriate sexual contact” and “taking their innocence away."
