A Massachusetts-based electrical company manager has admitted his involvement in a fraudulent scheme that defrauded the contractor managing Boston's commuter rail system of over $4 million. John Rafferty, 69, from Hale's Location, New Hampshire, pleaded guilty on Tuesday to conspiracy charges related to wire fraud, according to federal authorities. Rafferty served as the general manager of LJ Electric, Inc., which provided services to Keolis Commuter Services—the company responsible for operating the Massachusetts Bay Transportation Authority's commuter rail network since 2014. Between July 2014 and November 2021, Rafferty allegedly spent millions on personal items including trucks, construction equipment, home supplies, and a $54,000 camper, which were supposedly for John Pigsley, a former Keolis assistant chief engineer, and his family and friends. Rafferty recovered the costs of these items by submitting false invoices to Keolis. He kept a portion of the profits for himself, with prosecutors stating that the funds could have been used for much-needed repairs to the transportation authority's infrastructure. Rafferty faces up to five years in prison and is scheduled for sentencing on September 18. Pigsley has pleaded not guilty and will appear back in court in July.
