I'm not very familiar with the original Sandusky case but with today's arrest of Jeff Sandusky, I had a quick look around and here are some important issues that need to be kept in mind and perhaps, revisited.

This article mentions the rumours surrounding the charity Second Mile: Jerry Sandusky Rumored to Have Been ‘Pimping Out Young Boys to Rich Donors’, Says Mark Madden

A wiki link about the Second Mile charity: https://en.wikipedia.org/wiki/The_Second_Mile

U.S. President George H. W. Bush praised the group as a "shining example" of charity work in a 1990 letter, one of that president's much-promoted "Thousand points of light" encouragements to volunteer community organizations. Citing Sandusky's work with The Second Mile charity to provide care for foster children, then U.S. Senator Rick Santorum honored Sandusky with an Angels in Adoption award in 2002.

Rick Santorum is a Knight of Malta: https://ivarfjeld.com/2012/01/06/rick-santorum-is-a-freemason-and-a-knight-of-malta/

From that article:

That is why it is rather shocking that 50 “Independent Baptist pastors” in Iowa, endorsed Rick Santorum. Their only demand, was that Santorum must make their own daughter, Michelle Bachmann his nominee for Vice President.

Michelle Bachmann has affinities with Haiti: https://sonomachristianhome.com/2014/11/michele-bachmann-opens-up-about-life-faith-freedom/

An interesting article which lists the board members of Second Mile and questions the disappearance of District Attorney Ray Gricar: The “Suiciding” of Pedophile Investigators

And finally, it seems that in May 2016, the Pennsylvania Attorney General's office is taking a second look at the Second Mile.

The question has to be asked, why did it take them five years ?
