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.

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.
