In January 2016, former Allentown Finance Director Gary Strathearn pleaded guilty to conspiracy to commit mail and wire fraud. Charging documents stated Strathearn steered a contract to campaign donors of Public Official No. 3. That same month, Allentown Controller Mary Ellen Koval resigned and pleaded guilty to conspiracy to commit honest services fraud. Charging documents stated that Koval conspired with Public Official No. 3 to steer contracts with the city and with the Allentown Parking Authority to campaign donors. On January 20, 2016 the Allentown City Council unanimously voted no confidence in the mayor and called on him to resign. Additional guilty pleas relating to the FBI investigation were made in April 2016. Campaign manager Mike Fleck pleaded guilty to one count of conspiracy to commit extortion and bribery offenses and a single count of tax evasion. According to court documents, Fleck worked with several unnamed public officials in Reading and Allentown to deprive citizens of their "right to honest services" through "bribery and kickbacks." Matthew McTish, president of McTish, Kunkel & Associates, an Allentown-based engineering firm, pleaded guilty to one count of conspiracy to commit bribery offenses. According to court documents, McTish donated to the campaigns of Public Officials No. 1 and No. 3 to secure municipal contracts in Allentown and Reading. In March 2017, Francis Dougherty, formerly a managing director for Allentown, pleaded guilty to one count of conspiracy to commit mail and wire fraud in an alleged effort to steer city contracts and other services to Pawlowski campaign donors. According to court documents, Dougherty conspired with Public Official No. 3 to steer the city's streetlight upgrade contract to a campaign donor of Public Official No. 3. He also threatened to fire a city employee who did not write bidding documents in a way favorable to a campaign donor, court documents say. Patrick Regan, a former vice president with The Efficiency Network (TEN), pleaded guilty to conspiracy to commit mail and wire fraud on June 12, 2017 in regards to the streetlight contract. According to court documents, Regan participated in a conspiracy with Dougherty to give Regan's company an advantage in the bidding process. Court documents state that Dougherty allowed Regan to rewrite the city's bidding documents for the contract and pass them through an intermediary, giving Dougherty a "degree of separation." Regan was told the process was designed to "eliminate competition," court documents state. Regan was also a donor to Pawlowski's mayoral, gubernatorial and U.S. Senate campaigns, according to campaign finance records.
