A former FBI agent who was involved in an investigation of former Missouri Gov. Eric Greitens in 2018 pleaded guilty to misdemeanor tampering with evidence in the case on March 23, a day before jury selection was set to start in his trial on seven felony counts, including perjury.
William Don Tisaby, 69, who is now a private investigator, was hired by St. Louis Circuit Attorney Kimberly Gardner to investigate allegations against Greitens in an invasion of privacy case. Greitens resigned in 2018 after the investigation began.
