Husband researched how to kill his wife on YouTube and Google before committing murder

In a shocking revelation, a man is alleged to have turned to the internet to research poisoning methods before executing a plan to murder his wife, as disclosed during a recent court proceeding.

James Toliver Craig, a 45-year-old dentist from Aurora, stands accused of the heinous act of poisoning his wife, Angela Craig, 43, leading to her untimely death. The Arapahoe County coroner has confirmed that Angela's life was tragically cut short due to lethal doses of cyanide and tetrahydrozoline, a decongestant commonly found in over-the-counter eyedrops.

Coroner Kelly Lear provided this chilling testimony during the preliminary hearing for James Craig, who now faces charges of first-degree murder and tampering with physical evidence in connection to his wife's death. For a more comprehensive account, the original article can be found on The Denver Post.

Internet searches and purchases of poison

Investigators have presented evidence suggesting that James Craig procured arsenic and cyanide just days before his wife's demise. He is also believed to have conducted online searches on how to poison someone, while simultaneously dealing with financial difficulties and an extramarital affair. The prosecution alleges that James Craig introduced the poison into the pre-workout protein shakes he regularly prepared for his wife.

In the weeks leading up to Angela's death, James Craig reportedly used a shared computer at his workplace to conduct numerous searches related to poison. His search history on YouTube and Google included alarming phrases such as “how many grams of pure arsenic will kill a human,” “Is Arsenic Detectable in Autopsy,” “Top 5 Undetectable Poisons That Show No Signs of Foul Play,” “how to make poison,” and “The Top 10 Deadliest Plants (They Can Kill You),” as per his arrest affidavit.

Aurora police detective Bobbi Olson testified that James Craig also sought answers to questions like “is arsenic detectable in an autopsy?” and “how to make murder look like a heart attack” a few weeks before his wife's death.

Sequence of events leading to Angela's tragic death

Police records indicate that James Craig placed an order for arsenic from on Feb. 27. The package arrived on March 4, and just two days later, his wife was rushed to a hospital exhibiting symptoms consistent with poisoning. She was discharged the same day, but her condition worsened, leading to her readmission on March 9, where she remained until March 14.

During Angela's hospitalization, James Craig reportedly ordered two additional poisons — cyanide and oleandrin — from medical suppliers. The cyanide was delivered on March 13. Two days later, Angela Craig was readmitted to the hospital with exacerbated symptoms. She subsequently suffered a heart attack, was placed on a ventilator, and her health rapidly declined until her passing on March 18.

Coroner Lear testified that two blood samples taken during Angela Craig’s hospital visit on March 15 showed an increase in the amount of cyanide in her body between about noon and 8 p.m. that day.

Defense attorney's counter-arguments and additional details

During cross-examination, James Craig’s attorneys proposed that the increased amount of cyanide detected could be due to Angela Craig continuing to absorb an initial dose of poison. However, Lear countered this argument, stating that the sharp increase suggested a new poisoning event within that roughly eight-hour window.

Both cyanide and tetrahydrozoline have similar effects on the body, Lear testified. The latter is found in eye drops like Visine, which are used to alleviate red-eye. Angela Craig had over 400 times the amount of tetrahydrozoline in her body than what is considered a therapeutic dose, Lear testified.

As Angela Craig's health deteriorated in the hospital, with doctors struggling to diagnose her condition, police allege that her husband was entertaining another woman, fellow dentist Karin Cain, who had flown from Texas to visit him in Colorado.

Alleged affair and statements from the other woman

Karin Cain, an orthodontist, spoke to ABC’s “Good Morning America” about her relationship with James Craig. She revealed that she was in the process of divorcing her husband of nearly 30 years when she met James Craig at a dental conference in February. She stated that their relationship lasted for three weeks.

“I don’t like that label,” Cain said. “If I had known what was true, I would not have been with this person.”

When asked if she thought Craig had killed his wife to be with her, Cain denied any such plans for their future together.

“There’s no way I’m motive,” she said.

The case continues to develop, with James Craig's arraignment scheduled for Aug. 29.
