Criminal investigation and arrests over deaths at Memorial Medical Center

The criminal investigation and arrests over deaths at Memorial Medical Center turned a disaster-era record of patient deaths into a disputed forensic and legal case. Investigators had to work with bodies recovered after prolonged exposure to heat, weigh toxicology results against incomplete medical histories, and distinguish evidence that drugs had been present from proof of how or why patients died. Anna Pou, Cheri Landry, and Lori Budo were arrested on four second-degree murder counts; the case ended with all charges dismissed in 2009.

From disaster deaths to a forensic inquiry

The inquiry unfolded against a hospital crisis in which the power system’s vulnerability had been recognized before Hurricane Katrina. Memorial’s plant operations director, Eric Yancovich, had studied storm-surge estimates showing that twelve to fifteen feet of water could surround a facility three feet below sea level. His calculations indicated that less than four feet of street flooding could send water over the loading dock, while parts of the emergency power distribution system were at or near ground level. He had warned that flooding could disable much of the medical center. This background established the extreme conditions surrounding the deaths, but did not itself answer what had happened to individual patients.

When the bodies were recovered after more than a week in the heat, Orleans Parish coroner Frank Minyard initially told Virginia Rider that autopsies would be of little use: decomposition had made blood testing impossible. A volunteer pathologist pointed out that drugs might remain detectable in more resilient tissues, including liver, brain, and muscle, or in fluid that accumulates in the abdomen after death. At the attorney general’s request, Minyard agreed to seek autopsies and tissue samples from patients who had died at hospitals and nursing homes across Orleans Parish. Eighteen sets of samples from Memorial patients were sent on September 22 to National Medical Services, Inc., a forensic toxicology laboratory in Willow Grove, Pennsylvania.

Toxicology and the limits of inference

An early report on eighteen cases found morphine in nine and midazolam in roughly five or six others. A later review of forty-one bodies from Memorial and LifeCare found that twenty-three tested positive for morphine, midazolam, or both. Those results established drug exposure in the tested remains, but they did not, by themselves, settle whether a drug caused a particular death, what dose had been given, or whether anyone intended to hasten death.

The distinction mattered because the samples came from bodies that had remained in high heat for an extended period. Laboratory director Robert Middleberg cautioned that postmortem tissue concentrations were not as straightforward to interpret as blood tests from living patients and urged the review team to consider each patient’s medical history. Investigators examined whether drugs might have been given in one large dose or accumulated after repeated doses, how kidney or liver disease could affect that accumulation, whether the combination was dangerous for patients not on respirators, and whether the timing of respiratory or blood-pressure effects matched the recorded times of death.

The case of the ninety-year-old LifeCare patient known as Miss Alice Hutzler illustrated the investigators’ questions. She was being treated for pneumonia. Morphine and midazolam were found in her liver, brain, and muscle, but neither appeared as a prescription in her chart, which was maintained until a few hours before her death was recorded on September 1. The chart described her as resting comfortably the previous afternoon, and her nurses recorded no pain or distress that night indicating a need for those drugs. The finding raised questions about her treatment, while the broader review still had to account for the limits of postmortem evidence.

Expert disagreement and the coroner’s decision

Minyard sought another opinion from Steven B. Karch, a specialist who argued that drug levels measured in a cadaver might not correspond to levels before death. After examining the cases, Karch advised that causes of death should remain undetermined because the bodies had been exposed to roughly 100-degree temperatures for ten days. Minyard gave substantial weight to this view, which was also shared by a toxicologist retained by Pou’s attorney.

Other experts disputed the implications. Forensic pathologist Michael Baden argued that uncertainty about the precise dose did not erase the finding that the drugs were present, and that he saw no competing cause of death. Cyril Wecht considered some detected levels exceptionally high. To test the objection that decomposition could change drug concentrations, he exposed samples from people who had died of overdoses to hot, humid conditions and compared them with refrigerated samples; he found no significant difference. The experiment was small, not definitive, and neither independently vetted nor published, leaving it as another piece of contested evidence rather than a conclusive answer.

Minyard considered the prospect of a trial in which forensic experts would sharply contradict one another and the prosecution might lose on reasonable doubt. He also believed that such a result could harm the city’s recovery. His deliberation therefore involved both conflicting scientific opinions and his assessment of the case’s possible consequences; the competing interpretations remained unresolved in the evidence described.

Arrests, publicity, and outcome

Pou, Landry, and Budo were arrested on four second-degree murder counts. The arrests were documented by the officers involved, and affidavits and arrest warrants accompanied the charges. In connection with the investigation, Pou left messages for L. René Goux and wanted to obtain her own lawyer before answering questions. The episode marked a shift from hospital response and forensic review to an adversarial criminal process, in which evidence, legal representation, and public interpretation became inseparable parts of the story.

That interpretation was shaped by extensive television coverage. On CNN, Nancy Grace repeatedly framed the case around the possibility of an “angel of death” and interrupted a guest who was explaining the loss of power, rising fear, and delayed rescue that preceded the injections. The contrast between that framing and the contextual account exposed how quickly an uncertain inquiry could be presented as a stark crime narrative. The charges did not result in convictions: all were ultimately dismissed in 2009. The dismissal closed the criminal proceedings, but the investigation’s central evidentiary tension remained visible—the presence of drugs could be documented, while their precise role in each death and the intent behind their use were matters of dispute.
