STATE COLLEGE, Pa. (AP) — An explosive sex abuse scandal and possible cover-up rocked "Happy Valley" on Saturday when former Penn State defensive coordinator Jerry Sandusky, once considered Joe Paterno's heir apparent, was charged with sexual assaulting eight boys over a 15-year period. Among the allegations was a 2002 incident in which a graduate assistant for the team said he saw Sandusky assault a boy in the shower at the Nittany Lions' practice center.
