(AP) — Jurors in the criminal trial of former Penn State University president Graham Spanier spent more than six hours deliberating Thursday without reaching a verdict regarding the child endangerment and conspiracy charges he faces in the Jerry Sandusky sex abuse scandal. The panel got the case after Spanier's attorneys declined to call any witnesses to counter accusations he acted illegally in handling a 2001 complaint about Sandusky, a former assistant football coach, showering with a boy. In a closing argument, Spanier attorney Sam Silver said there was "no evidence" and the case involved judgment calls by high-ranking university administrators in dealing with the complaint Sandusky had been seen naked with the boy in a team locker room. Prosecutor Laura Ditka said Spanier, former athletic director Tim Curley and former vice president Gary Schultz took actions to preserve the university and their own reputations, at the expense of children. During deliberations, the Spanier jury twice returned to the courtroom, asking the judge about what makes someone a supervisor of a child under the law, what constitutes a criminal conspiracy and how the law defines reckless. The abuse scandal sent shockwaves through the Penn State community, led to the firing of Hall of Fame coach Joe Paterno, who died of cancer in early 2012, and ultimately led the university to pay more than $90 million to settle civil claims.
