The full returns from an investigation Mason calls "unprecedented in scope and magnitude" won't be known until Dec. 3. That is the day when nine members of the grand jury will cast their votes on whether to indict any of the 100 priests or 260 others connected with the diocese who have been accused of sexually abusing children. For an indictment to happen, seven grand jurors must vote yes. Mason said he expects several priests will be indicted, but he wouldn't speculate how many. He characterized about half a dozen of the cases as "tough calls" that could go either way, depending on the grand jury's mindset. But most of the cases are either too old or too weak to be prosecuted, Mason said.
