Much of the money former Warsaw Public Works Superintendent Lacy Francis received in a scheme to overbill the city for contract work was laundered through a Ponzi operation. According to our partner in news — The Times Union — investigators found seven dates when checks were sent to Rex Venture Group, which was later shut down by the U.S. Securities and Exchange Commission. After the checks were sent, another six checks were sent by friends, relatives and at least one former Warsaw city employee. Prosecutors say charges haven't been filed against any of those people as this time.
