HARRISBURG — One of the two defense lawyers who represented former Penn State assistant football coach Jerry Sandusky at trial is being investigated for the potential theft of money from his clients, a prosecutor said Monday.

Cumberland County District Attorney David Freed released a statement that said he learned last week about allegations against Karl Rominger that concern a divorce case. Freed said Rominger's defense lawyer, Bill Costopoulos, provided additional information and expressed a desire to cooperate.

“My office is leading an investigation into the potential misappropriation of a significant amount of client funds by Rominger,” Freed said.

Rominger told The Associated Press on Friday that he's “cooperating completely” and referred further questions to Costopoulos, who was not immediately available for comment.

Norris Gelman, the lead lawyer in Sandusky's pending appeal of his 45-count child molestation conviction, said Monday that Rominger's representation of Sandusky ended some time ago. Gelman said the allegations regarding Rominger were highly unlikely to affect Sandusky's case. In an audio statement released on his Facebook page, Rominger said he had “wronged” others.
