Former Penn State assistant football coach Jerry Sandusky's child sex abuse trial begins today in Bellefonte. He is charged with 52 counts and will face 10 accusers during his trial. The proceedings are expected to last three weeks.

BELLEFONTE — The trial of Jerry Sandusky, which will begin Monday when prosecutors and his lawyer make opening statements before a central Pennsylvania jury, will probably be over in a few weeks.

But when it comes to getting to the bottom of what happened, it will definitely not be the final word.

Testimony in the child sex abuse case will focus on the 52 counts and 10 accusers for which the 68-year-old former Penn State assistant football coach could, if convicted, spend the rest of his life behind the bars of a state prison.

However, there are many other questions being asked in a number of forums that would have to be answered for the complete story to come to light.

First and foremost, the state attorney general’s office has repeatedly indicated it has an “active and ongoing” related investigation, and the mere existence of the open investigation suggests additional criminal charges could result.

The university has said its president has been in talks with state prosecutors about when he will appear before a grand jury to answer questions, and Penn State disclosed last month that it would cover legal expenses of eight employees who also received subpoenas this year.

Citing a gag order, a spokesman for the attorney general declined to comment on the current status of the investigation, which is also obscured by the secrecy rules that govern operation of investigative grand juries in the state.

There also clearly is a federal investigation, but there are few details beyond the fact that Penn State said that in February it had been issued a wide-ranging subpoena from the U.S. attorney’s office in Harrisburg, seeking computer records and other information. Amanda Endy, a spokeswoman for the office, said Thursday that federal prosecutors have not commented on the topic and declined a request to discuss any update.

The state grand jury that investigated Sandusky reported one accuser claimed to have been sexually abused while attending bowl games with Sandusky in Florida or Texas, which could raise legal issues best addressed by the federal system.

Penn State has spent millions of dollars already on its own investigation into the matter, led by former federal judge Louis Freeh, who spent eight years as FBI director. That report is expected to be issued after the Sandusky criminal trial ends, perhaps in August, and should add substantially to what is known about the scandal.

“They’ve interviewed over 400 current and former employees from numerous departments, such as the academic, administrative, and athletic departments; current and past trustees,” university spokesman Dave La Torre said Thursday.
