A Northfield woman pleaded guilty in federal court for diverting fentanyl from an ICU patient at Concord Hospital. Lisa Richardson, 48, pleaded guilty to one count of Tampering with Consumer Products. US District Court Judge Landya McCafferty scheduled sentencing for January 16, 2025. On December 30, 2022, while working as a nurse at Concord Hospital, Richardson removed a quantity of fentanyl from an intravenous line bag inserted in an Intensive Care Unit patient. She then replaced the fentanyl with saline. The defendant was not assigned to the patient’s care as part of her duties as a nurse.
