This week, Penn State University fired both its legendary football coach and its president for keeping quiet about a sexual abuse scandal involving a former assistant coach. The assistant coach is accused of molesting eight boys over a 15-year period. And for years, it went unreported. Penn State is a high-profile case, but Lynn Huylar, who heads a children’s advocacy center in Cheyenne, says what happened there is typical of abuse cases everywhere. She says usually, the perpetrator isn’t a stranger, but rather someone the child knows very well.
