DENVER — Just a few days before her untimely death due to puzzling symptoms that baffled her doctors, Angela Craig confronted her husband, James, in their kitchen in a Denver suburb, regarding his lack of support.

In the 2023 dispute, captured by home surveillance footage, she accused him of implying to hospital staff that she was suicidal, according to court filings.

Prosecutors allege that James Craig was responsible for the health issues that led to his wife’s death by poisoning her protein shakes, attempting to disguise it as a suicide. His trial for murder and other related charges is slated to begin Monday, with jury selection commencing.

Angela Craig, 43, died in March 2023 during her third trip to the hospital that month. Toxicology tests later determined she died of poisoning from cyanide and tetrahydrozoline, an ingredient that is found in over-the-counter eye drops.

The couple were married 23 years and had six children.

Craig has pleaded not guilty to charges including first-degree murder, solicitation to commit murder and solicitation to commit perjury.

Police say Craig tried to fabricate evidence to make it appear his wife killed herself

The 47-year-old dentist allegedly bought arsenic online around the time his wife began to experience symptoms like dizziness and headaches for which doctors could find no cause, prosecutors say.

At the time of his arrest, police said Craig was trying to start a new life amid financial troubles and appeared to be having an affair with a fellow dentist. Prosecutors said he had affairs with two other women, but they have not detailed a motive in his wife’s death.

Craig’s attorneys have argued police were biased against him and claimed testing of his wife’s shake containers did not turn up signs of poison. They’ve questioned the reliability of a jail inmate who said Craig offered him $20,000 to kill the case’s lead investigator, an alleged plot for which Craig is also on trial.

To avoid being held accountable, prosecutors said, Craig tried to fabricate evidence to make it appear his wife killed herself.

He tried to get another fellow inmate to plant fraudulent letters at Craig’s home to make it look like his wife was suicidal, prosecutors said. Then, in the weeks before Craig had been set to stand trial in November, prosecutors said he also sent letters to the ex-wife of the inmate he allegedly tried to get to kill the investigator, offering her $20,000 for each person she could find to falsely testify that his wife planned to die by suicide, they said.

Previous Craig attorneys withdraw from case

As jury selection was about to begin, his lawyer at the time, Harvey Steinberg, asked to withdraw, citing a rule allowing lawyers to step down if a client persists in actions considered criminal or that they disagree with.

Another attorney for Craig, Robert Werking, later argued that investigators did not look into whether Craig wrote the letters or check them against his handwriting. Werking also said that the inmate and his ex-wife were prosecuted for forgery for their roles in an alleged fraud ring in 2005, suggesting they could not be trusted.

Werking withdrew from the case himself this month after being charged with arson of his own home, leaving his wife and law partner, Lisa Fine Moses, to defend Craig. Werking’s attorney, David Beller, said he was getting mental health treatment and asked the public to show him grace.

Moses did not immediately return telephone and email messages seeking comment.

Prosecutors plan to show video of couple’s argument

Over the objections of the defense, prosecutors plan to show the video of the argument in the kitchen to jurors.

“It’s your fault they treated me like I was a suicide risk, like I did it to myself, and like nothing I said could be believed,” Angela Craig told her husband after her first trip to the hospital.

Prosecutors convinced the judge jurors should see the video because they said it disproves potential claims that Angela Craig poisoned herself – possibly while trying to dissuade him from divorcing her – or to frame him and gain an advantage over him if they did divorce.

“Her mental state is anger and frustration, not suicidality or desperation to keep the defendant in the marriage,” Senior Chief Deputy District Attorney Michael Mauro wrote in a recent court filing.

One of Angela Craig’s siblings, Mark Pray, said last year that James Craig not only orchestrated the “torment and demise” of his sister but had shown disregard for others, including their children.

An online search

Prosecutors say James Craig searched online for answers to questions such as “how to make murder look like a heart attack” and “is arsenic detectable in an autopsy?”

After Craig’s initial attempts to kill his wife failed, prosecutors allege, he ordered a rush shipment of potassium cyanide, supposedly for surgery. The shipment was accidentally discovered by an employee at his dental practice in the Denver suburb of Aurora on March 13, 2023. The employee reported it to the office manager two days later when Angela Craig returned to the hospital for a third and final time.

Craig’s business partner, Ryan Redfearn, told a nurse treating Angela Craig that he was concerned she could have been poisoned with the cyanide. The nurse reported that to police, who began their investigation the same day.

Angela Craig died days later.
