Raynaldo Riviera Ortiz Jr., a Texas anesthesiologist, was convicted of federal charges for tampering with IV bags, leading to multiple patient emergencies and one death. His actions, described as those of a 'medical terrorist,' involved injecting dangerous drugs into the bags used during surgeries at a North Dallas facility in 2022. Prior to these events, Ortiz had a history of violent behavior, professional reprimands, and financial difficulties. The unexplained medical crises prompted an investigation that revealed Ortiz's deliberate tampering, captured on surveillance footage. Despite his claims of innocence, evidence presented at trial detailed the suffering of his victims, ultimately resulting in a 190-year prison sentence. The case underscores the violation of patient trust and the serious consequences of intentionally adulterating medical products.
