Imagine placing your life in the hands of a trusted doctor, only to wake up in the ICU fighting for survival because the same physician tried to kill you. This chilling scenario became a horrifying reality for unsuspecting patients who crossed paths with Dr. Raynaldo Rivera Ortiz Jr., a Dallas anesthesiologist who maliciously tampered with IV bags and transformed routine surgeries into near-death experiences. On April 12, 2024, justice came calling. A jury found Dr. Raynaldo Rivera Ortiz Jr., 60, guilty of tampering with patients’ IV bags at Baylor Scott & White Surgicare North Dallas between May and August 2022. Ortiz was convicted on charges including tampering with consumer products, resulting in serious bodily injury and intentional adulteration of a drug. He faces up to 190 years in prison.

But why? What makes a physician who dedicated his career to helping others decide to use his skills to hurt them? The research shows us that the motive of a medical murderer can range from money, a sense of sadistic pleasure, revenge, or simply because they can. The specific path that led Ortiz to this point — violating his oath in such an egregious way and unleashing terror on unsuspecting patients — merits a closer look. A glance at his background shows us some strong clues:

Red Flags Were Waving

Court records and medical board filings paint a disturbing picture of Ortiz’s conduct dating back over two decades. In 1995, he was arrested for assault causing bodily injury to his spouse. In 2005, a second partner filed for an emergency protective order against him. And in 2014, he was arrested again for domestic violence against a third partner.

This alleged pattern of intimate partner violence points to poor impulse control, a lack of empathy, a need for control, feelings of entitlement, and an inability to take responsibility for one’s actions — personality traits that also likely contributed to Ortiz’s later criminal behavior targeting patients. Abusers often escalate their aggression over time if left unchecked.

Animal cruelty is another well-established warning sign, as it indicates a lack of empathy and disregard for life. In 2014, Ortiz shot his neighbor’s dog in the chest with a pellet gun after the neighbor helped Ortiz’s ex-girlfriend move out following a domestic dispute. He was convicted of misdemeanor animal cruelty.

Although these incidents were disturbing, they were unrelated to his competency as a doctor. Ortiz continued practicing medicine. However, he started coming under increased scrutiny for surgical mistakes and deviating from standards of care. In 2018, the Texas Medical Board reprimanded him for failing to report his criminal charges. In 2020, a patient required emergency resuscitation after Ortiz performed anesthesia. By May 2022, he was being investigated by the surgery center and expressed anger to colleagues, suggesting it could ruin him financially if he lost his job there.

As a forensic psychologist, this stands out to me as a tipping point. An individual with a history of domestic abuse and animal cruelty, suddenly facing severe professional consequences, is at risk of lashing out if they feel criticized, slighted, and unable to control the narrative. This fear of losing status, combined with long-standing anger issues and a lack of empathy, could have been the psychological powder keg that ignited Ortiz’s vengeful plot against patients and colleagues.

A Sinister Plot Unfolding

Investigators believe Ortiz began his IV bag tampering scheme shortly after the surgery center informed him of the inquiry into his May 2022 surgical incident. Just two days later, patients started experiencing unexpected complications during routine procedures.

According to prosecutors, Ortiz would inject saline IV bags with dangerous drugs, including epinephrine, Bupivacaine, and lidocaine. He knew this unapproved cocktail could cause serious reactions. He allegedly placed the tainted bags in a warmer in the hall outside the operating rooms, waiting for them to be unknowingly picked up and used by other anesthesiologists during surgeries. Ortiz would refuse to use the warmed bags — a sign he likely knew they’d been tampered with.

From a psychological perspective, this calculated modus operandi suggests a few key motives:

  1. Revenge against colleagues he felt were “crucifying” him in the disciplinary process
  2. A desire to deflect scrutiny by causing surgical emergencies for other doctors
  3. Excitement from secretly orchestrating and watching harmful events unfold
  4. A sense of power and control from holding patients’ lives in his hands

In June 2022, Ortiz’s tampering inadvertently killed a colleague. Fifty-five-year-old fellow anesthesiologist Dr. Melanie Kaspar took an IV bag home from the surgery center to rehydrate from an illness. Unfortunately, it happened to be one that Raynaldo Ortiz had doctored. Soon after hooking herself up to the IV line, she began screaming. Her husband rushed to her side, only to see her collapse with the IV line still in her arm. She suffered a fatal heart attack.

The tainted IV bags continued wreaking havoc that summer as confused doctors saw patient after patient suffer mysterious heart failures and skyrocketing blood pressure during surgeries. At least ten patients had to be rushed to ICUs and placed on ventilators after experiencing near-fatal complications. An 18-year-old undergoing a routine nose surgery after a dirt bike accident was among those who narrowly escaped death. Something had to be done.

Unraveling the Evidence

The Dallas Surgery Center administrators began carefully tracking the incidents and reviewing safeguards. Ortiz sent IV bags from the warmer to be tested; investigators discovered tiny puncture holes into which Bupivacaine, a potent local anesthetic, had been added to these bags.

Investigators also turned to video surveillance footage, where they discovered chilling evidence of Ortiz executing his scheme and watching the fallout. Cameras captured him placing IV bags in the warmer, looking around furtively, and then lurking as his victims were rushed out of the facility in ambulances. The timestamps aligned with the cardiac emergencies erupting in the operating rooms.

Ortiz’s actions went against the typical protocol for anesthesiologists, who never retrieved their own IV bags. He was seen suspiciously swapping out IV bags from the warmer on multiple occasions just before unsuspecting patients suffered life-threatening reactions. On one occasion, he refused a bag a nurse had retrieved from the warmer for his own surgery, suggesting he knew it could be tainted. When Ortiz went on vacation, the incidents stopped. When he returned, they resumed.

As investigators closed in, it became clear that Ortiz had exploited vulnerabilities in the surgery center’s processes to access and tamper with the IV bags. Driven by anger, revenge, and a lack of regard for human life, he unleashed a reign of terror on patients and set his colleagues up for devastating outcomes. The pain, fear, and trauma inflicted on the victims who suddenly found themselves fighting for their lives due to Ortiz’s actions is immeasurable.

Lessons Learned

Dr. Raynaldo Ortiz’s misdeeds remind us how much trust we place in medical professionals and how violations of that trust can cause disastrous consequences. It also illustrates how domestic violence, animal abuse, and other warning signs must be taken seriously as possible indicators of escalating aggression that could cross over into the workplace. We so often see violence start in the home and then bleed out into other spaces via mass shootings, murder-suicide, spree killings, and workplace assaults. Perhaps it should come as no surprise that, this time, it traveled from the bedroom to the operating room.

This case also underscores the critical importance of robust checks and balances in healthcare settings to prevent and quickly identify intentional harm by rogue actors. Hospitals need improved medication storage, access, and tracking protocols to avoid tampering. Video monitoring, which helped uncover the truth in this case, should be expanded. Regular reviews of providers’ quality metrics and complaints help surface problems earlier. Quick investigations and decisive action after serious incidents are also vital.

The Bottom Line

The vast majority of physicians uphold the Hippocratic Oath with the utmost integrity. But the consequences are shattering when outliers like Ortiz warp their immense skill and power to inflict harm instead. Innocent people suffered terrifying ordeals of waking up intubated, not knowing if they would survive, because of the cruel actions of someone entrusted with their care. The sense of betrayal is unfathomable.

Vigilance is an acceptable price to pay when the stakes are so high. Ortiz’s criminal acts, born of revenge and disregard for human life, shattered the sacred bond between healer and patient, forever changing the lives of his victims. Even if he spends the rest of his life in prison, what is true justice for his victims? They must all live with the trauma of having been betrayed when they were at their most vulnerable by a doctor who swore to do no harm.
