(CBS News) BELLEFONTE, Pa. - Jerry Sandusky may not have seen the last of prosecutors' allegations, according to one legal analyst.
Sandusky was convicted of 45 of 48 child sex abuse counts against him and is already facing a possible life sentence as a result.
But, says Jean Casarez, a correspondent for truTV's "In Session," there "could be more prosecutions, because we know the grand jury has been continuing to hear testimony through these months. We know there are other accusers who have stepped forward, even Matt Sandusky, the adopted son of Jerry Sandusky, (who) is now saying through his lawyers that he was abused.
"So there may be more prosecutions in this case against Jerry Sandusky."
Casarez told "CBS This Morning: Saturday" co-hosts Anthony Mason and Rebecca Jarvis, "We don't know when he came forward. And it appears as though it was very, very late in the game that he came forward. Why did he wait until then? We don't know. We can't get inside his mind.
"But it is believed that (the prosecution) would have used him as a rebuttal witness and that may be why, at the very last minute, Jerry Sandusky did not testify, because we all thought he was going to take the stand."
In addition, Casarez pointed out, Penn State officials "just have to sit and wait" to see if they or the school get in any more legal hot water.
"There's an internal investigation going forward with the university," Casarez notes. "There will be many, many civil lawsuits for the university. They will just have to sit with their attorneys and deal with all of it."
