07/23/2025 - How Expert Witnesses Are Key in Dr. James Toliver Craig's Murder Trial


Accusations have emerged against Dr. James Toliver Craig, a 47-year-old Aurora, Colorado dentist, who stands charged with the meticulous murder of his wife, Angela Craig. Authorities suggest the husband used a rare and deadly poison over a period of time, dosing his wife in small amounts to avoid detection. The prosecution team has opened with a strong allegation of premeditated murder, and its case has apparently caused at least one defense witness (an expert in the type of poison said to have been used) to alter his story when retelling it to investigators. Paul O'Brien, the District Attorney for the 18th Judicial District, appears to have energized his team with the momentum of a pretty solid first couple of prosecution days.

The Alleged Murder
Allegations facing Craig involve poison, specifically potassium cyanide and tetrahydrozoline, a chemical in over-the-counter eye drops. Prosecutors say he used it to kill his wife in a slow, deliberate manner. Craig is accused of buying the toxic substances while pretending to be someone else and of meticulously lacing his wife's protein shakes with them. The prosecutors say that any apparent love he might have had for his wife was a sham, one that covered up an affair he was having.

Angela Craig, a 43-year-old mom of six, started showing worrisome signs just after drinking the supposedly contaminated beverages. Between March 6 and March 15, 2023, she went to the hospital not once but several times, for a dizzying array of reasons. She was sick—really sick, with what you might call an assortment of undiagnosed conditions that had her fainting, feeling dizzy, and life-threateningly nauseated. On March 15, without any known cause, she collapsed. And in the hours that followed, doctors told her husband that she had suffered a massive brain blow and was now dead.

Key Medical Testimony
Some of the trial's most compelling early testimony was given by two medical experts, Dr. Peter Sottile and Kristin Aubuchon, RN. Their work and observations set a clear path for the prosecution to follow. They provided a whole lot of poison-proofing.

Dr. Peter Sottile – Pulmonology and Critical Care
A well-respected pulmonologist and critical care expert, Dr. Sottile, was one of the first medical professionals to attend to Angela Craig during her last hospitalization. On the stand, he labeled her condition as "profoundly alarming." Angela's brain was swelling; her blood work was showing abnormalities that just did not match up with any typical metabolic disorder.

Dr. Sottile testified that when he told James Craig that his wife was probably brain dead, Craig's reaction was emotionally flat and distant. "He displayed no emotion that one would expect under those circumstances," Sottile said, "and immediately inquired if they had done enough to bring her back to life." Such an immediate question about the wife's condition from the husband was strange, the doctor said.

Kristin Aubuchon – Registered Nurse
Nurse Kristin Aubuchon, who was with Angela during her hospitalization, offered moving testimony concerning Angela's last days. With 23 years of nursing experience, Aubuchon detailed Angela's transition into unconsciousness and how very quickly her condition went downhill. Her observations added a lot of emotional description to the scientific testimony given by Dr. Sottile.

Toxicology Findings and the Coroner’s Report
A key evidence piece lies in the toxicology results and the autopsy report. According to the Adams County coroner, Angela Craig had in her system at the time of death nearly twice the lethal dose of potassium cyanide. Furthermore, she had consumed more than 400 times the therapeutic dosage of tetrahydrozoline. These findings make it highly unlikely that Angela could have ingested the substances accidentally, which bolsters the prosecution's theory that her husband killed her in a calculated murder.

Likely Expert Witnesses to Appear
Expected to Be Called: Several categories of expert witnesses are forecasted for dispatch as the trial rolls onward.

1. Forensic Toxicologists
The effects of cyanide and tetrahydrozoline on the human body will very likely be the realm of toxicologists. They will explain the deadly nature of the two substances, give us a good understanding of just how lethal they are, and tell us what might happen if you were to mix the two together and ingest them. They're going to be very key people in affirming that whatever was found in Angela's system was not something that could have occurred naturally or even by accident.

2. Forensic Pathologists
The cause of death may be established by the medical examiner or independent pathologists who might also testify to correlate symptoms with poisoning and clarify whether the death could be consistent with any other explanation. These witnesses might also be essential for countering any potential defense theories suggesting alternative medical explanations.

3. Digital Forensics Experts
Since James Craig is now charged with the crime of poison research; an understanding of the case relies on digital forensic analysts. These experts can tell us whether Craig's online behavior was criminal or not.

4. Psychiatrists or Behavioral Analysts
Should the defense claim that Angela Craig might have ingested the substances on her own or that she might have had suicidal inclinations, the prosecution could surely counter with well-reputed mental health professionals. Such experts could—we might even say would—testify to Angela's state of mind, the nature of her relationships, and her personal and family history.

Defense Strategy and Outlook
The defense has thus far sought to depict Angela as being of questionable mental stability, hinting that she may have intentionally consumed the sorts of harmful substances that could account for her current condition. This theory is unproven, and as of this writing, no expert witnesses for the defense have been called to bolster this claim.

James Craig has entered a not guilty plea for first-degree murder charges against him. His defense has spent considerable time arguing for his innocence, stating that while Craig may have not been faithful in his marriage, there is no direct evidence that links him to the heinous crime of poisoning his wife. Yet, even with all the testimony and argumentation in his favor, a jury still has to be convinced beyond a reasonable doubt that Craig is not guilty of this act.

Conclusion
Dr. James Craig's trial is shaping up to be a landmark case in Colorado. The expert witnesses called to testify are taking center stage. Toxicologists and other medical specialists are helping the jury sort through an unusually large volume of scientific and circumstantial evidence. Whether their testimony makes Craig seem guilty or tenders him as a reasonable doubt may well be the deciding factor in whether he walks out of the courthouse a free man or goes to prison for the remainder of his life.
