YOUNGSTOWN — The final witness in the attorney Robert J. Rohrbaugh II trial testified Monday in U.S. District Court, and jurors will hear closing arguments and jury instructions today before they begin to deliberate.

Rohrbaugh, 49, of Canfield is being tried a second time on conspiracy, aiding and abetting the theft of government property, aiding and abetting a false tax return and conspiracy to commit money laundering.

The charges relate to co-defendant Brandon Mace, 45, who is from the Youngstown area, a client Rohrbaugh has represented many times over the years on many fraud and theft cases.

Mace filed several fraudulent federal tax returns in 2015 while he was an inmate in a federal prison, and the IRS issued a $1.3 million refund for one of them for a fictitious company called Speed Werks.

Rohrbaugh is charged with aiding and abetting Mace and co-defendant Terris C. Baker, 49, of Canton so that the $1.3 million IRS check could be cashed and for helping Mace and Baker in the scheme in other ways.

Mace was one of the witnesses who testified last week. He pleaded guilty to similar charges earlier and is cooperating with prosecutors. Baker was found guilty of similar charges during a trial in April. Rohrbaugh also was on trial with Baker, but jurors could not decide Rohrbaugh’s guilt or innocence on most charges, and prosecutors chose to try him again. The jury found Rohrbaugh not guilty of filing false tax returns.

Also testifying in the trial was Kasey McCollum, longtime assistant in Rohrbaugh’s office, which is on Belmont Avenue in Liberty. Judge Benita Y. Pearson is presiding over the trial, which began last Tuesday.

McCollum also testified at the first trial, telling the jury she worked for Rohrbaugh for about 20 years, including when their office was on Market Street in Boardman until about four years ago.

She testified that she knew Baker only by name, but she knew Mace much better because Rohrbaugh had represented Mace “for many years.”

She said Rohrbaugh told her in 2015 that Mace had a $1 million IRS refund check. When she heard it, she viewed it as “Brandon was being Brandon again” and agreed under questioning by assistant U.S. Attorney Erica Barnhill that Mace was a “career criminal” who repeatedly had been involved in financial fraud.

She testified that she believed the refund check was fake until she learned that the Boardman KeyBank branch cashed it. McCollum took care of the financial transactions for Rohrbaugh’s business.
