SPRINGFIELD, Mo. (AP) — Federal prosecutors say two former executives of a Missouri-based health nonprofit pleaded guilty for their roles in a corruption scheme that involved several Arkansas officials. Sixty-three-year-old Bontiea Bernedette Goss and her 66-year-old husband, Tommy Ray Goss, pleaded guilty Wednesday to conspiracy charges. They were executives at Springfield, Missouri-based Preferred Family Healthcare, which provided health-related services to five states. Prosecutors say the couple and others paid bribes and kickbacks to Arkansas lawmakers in exchange for legislation and other actions that helped the charity. The scheme involved millions of dollars and ensnared several Arkansas legislators and lobbyists since the investigation began.
