Trussville Resident, Ex-FBI Agent Indicted On Perjury Charges

ST. LOUIS, MO - A former FBI agent and current Trussville resident was indicted last week on charges of perjury and evidence tampering. William Don Tisaby, 66,was indicted on seven felony charges in St. Louis, according to an indictment unsealed on Monday.

A report by the St. Louis Post-Dispatch said Tisaby has been under investigation by a special prosecutor who is looking into allegations that he lied during a March 2018 deposition in the lead-up to former Gov. Eric Greitens’ criminal trial.

The indictment accuses Tisaby of concealing a series of documents from defense attorneys and lying under oath during the deposition “about matters that could substantially affect, or did substantially affect, the course or outcome of the Greitens case.”

Tisaby’s indictment also opens a series of claims against St. Louis Circuit Attorney Kimberly M. Gardner: that she failed to correct Tisaby’s lies, failed to report them to police, and made incorrect statements to defense lawyers and a judge.

News broke in January 2018 that Greitens had had an affair with his hairdresser as he was preparing to run for office. The woman’s ex-husband claimed Greitens threatened to release a photo of her partly undressed if she exposed their affair, which Greitens denied.

Gardner began an investigation that month. On Jan. 18, she hired Tisaby, on the recommendation of another former FBI agent working in her office, despite a past allegation that Tisaby had lied to FBI internal investigators looking into a bigamy claim. On Jan. 24, Gardner interviewed Greitens’ accuser without Tisaby. Five days later, Tisaby interviewed the woman, with Gardner present. In February, a grand jury indicted Greitens.

The indictment says Tisaby lied about information Gardner provided him before he first interviewed Greitens’ hairdresser. He told defense attorneys she gave him no information. But the indictment says Tisaby and Gardner spent hours on the phone before that interview and exchanged more than 100 text messages.

Circuit Judge Rex Burlison released Tisaby on his own recognizance on Monday.
