The Investigation Unveils a Nurse's Actions of Tampering with Medications

A nurse named Donna is accused of tampering with medications at the Yale Clinic. She initially starts taking fentanyl at work, then continues taking it home. Donna replaces the fentanyl with saline and returns the tampered vials to the stock at work. Eventually, an anesthesiologist notices a loose cap on a vial, leading to an investigation. Donna confesses and is terminated. Patients receive letters from the Department of Justice, revealing Donna's name and causing them to question her actions and motives.
