Federal agents have arrested two women and a man, after linking them to a ring that staged fake car crashes to defraud insurance companies through massage therapy and chiropractor services for “victims” who didn’t need medical treatment, according to federal court records. The ring operated between 2012 and 2014, but it was only this month that agents busted the group. In all, the defendants pocketed more than $1.6 million over two years, according to court documents. The defendants — Guillermo García, 46, Mayre López, 39, and Taymi González, 35 — pleaded not guilty and are awaiting trial.
