Mary Leaver, a spokeswoman for DHS, said the agency could not comment about the charges against Roberts, who is on paid administrative leave. Roberts also is a defendant in a lawsuit filed in Tulsa County District Court last week, alleging that she conspired to defraud evangelist Martha Vicki Peterson, who was in DHS custody before her death at age 71 in January. Judith Upjohn, another defendant in the lawsuit, was a longtime friend of Peterson's who took the evangelist into her home after DHS took guardianship of her. The lawsuit, filed on behalf of Peterson's estate, alleges negligence and breach of duty on the part of DHS and Roberts in failing to protect Peterson's assets. It alleges that DHS and Roberts paid tens of thousands of dollars of Vicki Peterson's money to Upjohn without accounting for the necessity or reasonableness of such payments. The suit requests damages exceeding $10,000 and an accounting of Peterson's income and expenses while DHS was her guardian. Peterson, an evangelist and faith healer, was a regular guest on Christian television shows in the 1970s and 80s. In 1982, her one-hour show, Vicki Live, was broadcast from Tulsa. DHS took Peterson into custody in 2005 in an emergency guardianship. In a court ruling, a judge stated there was significant evidence that her husband, Dr. Carl Peterson, gave psychotropic medicine to his wife against her best interest and against her physician's advice.
