When Kathy Augustine was taken to a hospital in July 2006, the immediate problem was medical: she was unresponsive and unable to breathe normally. The criminal question emerged through a coworker’s recollection of something Augustine’s husband had said the previous day.

Chaz Higgs was a nurse. The coworker, Kim Ramey, later testified about a conversation involving his marriage and a powerful medication. After Augustine’s collapse, Ramey passed her concerns to authorities and medical staff. A sample obtained while Augustine was alive became central to the investigation.
A jury convicted Higgs of first-degree murder in June 2007. The case subsequently reached the Nevada Supreme Court, where disputed scientific evidence and the defense’s opportunity to challenge it became major issues. The court affirmed the conviction in a published 2010 opinion. [1] [2]
A marriage under strain
Augustine and Higgs married in 2003. By the summer of 2006, according to the trial evidence summarized on appeal, the relationship was deteriorating. The prosecution used his statements about the marriage to establish a context for what happened next.
The important conversation occurred on July 7. Ramey described Higgs discussing marital difficulties and referring to succinylcholine, a drug used in medical settings. The significance of that account did not depend simply on his professional familiarity with a medication. It depended on what she said he had expressed, and on the medical emergency that followed.
July 8: a medical emergency
On July 8, Augustine was found unresponsive. Emergency personnel restored a heartbeat, but she required hospital treatment and respiratory support. She did not recover. She died on July 11 after life support was withdrawn.
Ramey’s concerns influenced the search for an explanation. Investigators and doctors considered whether Augustine had been exposed to a drug outside legitimate treatment. The relevant medical records did not show emergency responders or hospital personnel administering the suspected drug.
That point mattered because a positive laboratory finding alone would not answer every question. If a drug had been given in treatment, its presence could have had an innocent explanation. The state therefore needed to connect laboratory results with the treatment history and the events before the ambulance arrived.
The prosecution ultimately argued that Higgs had caused Augustine’s collapse. The defense challenged both that account and the scientific support offered for it. Neither the marriage’s difficulties nor his occupation eliminated the state’s burden to prove a criminal act. [1]
One investigation, different samples
The laboratory story was more complicated than a universal positive result.
An FBI analysis of urine collected while Augustine was alive supported the state’s contention that she had been exposed to succinylcholine. Tests on material collected after death did not supply the same positive finding. The difference between those samples became part of the case, rather than a detail that could be removed from it.
For jurors, the questions included whether the testing method was reliable, whether the analysts were qualified to explain it and what conclusions the result justified. The defense sought to scrutinize the methodology and argued that it needed additional time and expert help to do so.
Those disputes were not merely arguments about unfamiliar vocabulary. In a prosecution alleging a medically induced death, the laboratory evidence connected the theory of a crime to the body of the person who died. If that connection were unreliable, the prosecution’s narrative would be materially weaker.
The state, in turn, presented expert testimony to support the analysis. The judge allowed the evidence, and jurors heard competing arguments about its significance. The published appellate opinion examines that decision at length. [1]
How a workplace conversation reached the hospital
The warning passed through several people. After hearing Higgs's disturbing remarks, coworker Kim Ramey told another colleague, who alerted Augustine's attending physician, Dr. Richard Ganchan. The doctor had been investigating a medical crisis. The new information introduced the possibility that the crisis had been deliberately caused. It did not itself establish that poisoning had occurred. [1]
That distinction became important to the handling of the samples. Urine had already been collected during Augustine's treatment. The Nevada Supreme Court later emphasized that its original purpose was medical care, rather than creating evidence for a criminal prosecution. Material from the investigation was eventually sent to the FBI when local testing could not answer the question investigators were asking. [1]
FBI toxicologist Madeline Montgomery described three analyses of the urine sample that yielded positive findings. Testing of tissue obtained after death did not produce the same result. The prosecution's explanation depended on the different materials and collection times; the defense questioned the methods and the inference drawn from them. Calling this simply a “positive toxicology test” would lose the disagreement that occupied the trial. [1]
Preparation became part of the appeal
The timing of the defense investigation also mattered. The court appointed expert Chip Walls in December 2006. A trial initially set for July 2007 was moved to June by agreement in January. In May, the defense sought more information about the testing and asked for additional preparation time. The appeal examined that request and the opportunity to challenge the laboratory work. [1]
These procedural details show why the laboratory illustration is a comparison of samples, not a recreated report declaring an unquestionable result. Jurors heard a contested scientific explanation alongside the coworker's account and the surrounding circumstances. [1]
The defense contests the reconstruction
Higgs’s lawyers challenged more than the central toxicology finding. Questions also arose about physical marks, the age of an injury and whether a suspected site supported the prosecution’s account.
These disagreements illustrate why the case cannot be reconstructed as though observers watched an injection and then followed an uninterrupted chain of known events. There was no such eyewitness narrative in the reviewed record. The prosecution assembled medical findings, testimony and circumstances; the defense disputed whether that combination established murder beyond a reasonable doubt.
The defense also argued that the trial schedule had prevented adequate preparation. Scientific evidence can demand access to laboratory material, consultation with specialists and time to understand what a test does and does not show. Higgs contended that the court had not allowed enough time for that work.
The appellate court rejected the grounds for reversal. Its decision upheld the trial judge’s handling of the evidence and proceedings under the legal standards it applied. That result should be reported as a court ruling, without suggesting that judges independently repeated the laboratory tests or that the defense never raised substantive objections. [1]
What Nevada’s high court decided
The 2010 opinion addressed the admission of expert testimony under Nevada law. The central issue was whether the evidence and the witnesses satisfied the requirements governing specialized testimony and whether the trial court had exceeded its discretion.
This is a different question from whether every scientific disagreement had disappeared. Trials routinely contain conflicting expert views. A judge’s decision to admit testimony permits the jury to consider it; the jury then decides what weight it deserves in relation to the rest of the case.
The court also considered the request for more preparation time. It did not find grounds requiring a new trial. Together, those rulings left the first-degree murder conviction in place.
A life sentence with a parole provision
The federal court’s later account of the proceedings records a June 2007 conviction and a sentence of life imprisonment with the possibility of parole after 20 years. That is not life without parole. It also does not mean automatic freedom after 20 years.
The later federal proceedings also addressed challenges to the conviction. [2]
Kathy Augustine’s case turned on the relationship between a human recollection and a scientific investigation. Ramey’s account helped prompt attention to a possibility that might otherwise have been missed. The hospital sample gave investigators something to test. The dispute over that test then became part of the trial itself.
The result was a murder conviction, but the path to it matters: an unexplained collapse, a warning from a coworker, contested medical evidence and a jury’s decision after hearing the competing accounts. Augustine’s death was the event those proceedings sought to explain. [1]
