The James Craig case featured on Dateline is the Colorado murder in which Aurora dentist James Toliver Craig fatally poisoned his wife, Angela, over ten days in March 2023 using arsenic, cyanide, and tetrahydrozoline. An Arapahoe County jury convicted him of first-degree murder on July 30, 2025, and he was sentenced to life in prison without the possibility of parole, plus 33 consecutive years for five solicitation felonies committed while he awaited trial. Dateline NBC told the story in a two-hour episode, “Secrets of Exam Room 9,” which aired September 5, 2025.
How Angela Died
Angela Craig was 43, a mother of six, and had been married to James since December 1999. On the morning of March 6, 2023, she drank a protein shake her husband prepared and began feeling dizzy, with headaches that sent her to AdventHealth Parker Hospital. She was discharged. Urgent care the next day produced no diagnosis. On March 9 she fainted at home and was readmitted; blood tests showed arsenic at 330 micrograms per liter.
She cycled in and out of the hospital that week. From one bed she texted her husband that she felt “drugged” and pointed out that a protein shake was all she had consumed. He wrote back, “Just for the record, I didn’t drug you.”
The final poisoning came March 15, after Angela was admitted to UCHealth University of Colorado Hospital. Prosecutors showed jurors hospital security footage they said depicted Craig holding a syringe before entering her room. Forensic toxicologist Dr. Justin Brower testified that her blood cyanide levels more than doubled during that hospital stay, from 3.7 micrograms per milliliter to 5.865 milligrams per liter, nearly twice the lethal threshold. She seized at 2 p.m., was placed on life support, declared brain dead on March 18, and removed from support the same day.
Arapahoe County coroner Dr. Kelly Lear ruled the death a homicide caused by acute cyanide and tetrahydrozoline toxicity, with subacute arsenic poisoning as a significant contributing condition.
How the Case Broke Open
The investigation started inside Craig’s own dental practice, Summerbrook Dental Group. On March 13, 2023, while Angela was hospitalized, a package of potassium cyanide arrived at the office. Craig had told staff not to open his personal deliveries. A staff member opened it anyway. Office manager Caitlin Romero recognized the chemical, looked up its effects, and connected the symptoms to Angela’s illness.
Romero alerted Dr. Ryan Redfearn, Craig’s business partner and a dental school friend of more than twenty years, who had taken over Craig’s financially struggling practice in August 2022. Redfearn confronted Craig by phone. Craig first said the package was a surprise ring for Angela. Told that Redfearn knew it was potassium cyanide, he changed the story: Angela had asked him to order it, he claimed, and described the situation as a “game of chicken.” Redfearn told him to stop talking and hire a lawyer.
Redfearn then called a nurse at the hospital treating Angela. The nurse, a mandatory reporter, notified the Aurora Police Department. Officers were at the hospital within hours. James Craig was arrested on March 19, 2023, the day after his wife was taken off life support.
The Evidence Against Him
Detective Bobbi Jo Olson led the investigation with her partner Detective Molly Harris. Over more than two years, they reviewed thousands of text messages, more than 1,000 hours of home surveillance video, and digital evidence from Craig’s office computers and personal devices.
The dental office computer in Exam Room 9 held the most damning material. Beginning in late February 2023, someone using a newly created email address tied to Craig searched for “how many grams of pure arsenic will kill a human,” “is arsenic detectable in autopsy,” “how to make murder look like a heart attack,” “a dosage of tetrahydrozoline that is fatal,” and “Top 5 Undetectable Poisons That Show No Signs of Foul Play.” Craig also watched YouTube videos about making poison.
Purchase records from the same computer showed arsenic ordered through Amazon, 19 packages of tetrahydrozoline eye drops bought from King Soopers, and potassium cyanide ordered from Midland Scientific, a laboratory supply company. Craig told the supplier the cyanide was needed for a “complex dental procedure.” Redfearn testified that there was no dental use for potassium cyanide.
Home surveillance footage caught Craig preparing shakes for Angela in the early morning hours on multiple days. A shaker bottle recovered from the home tested positive for tetrahydrozoline, the active ingredient in Visine and similar eye drops.
Why He Did It
Prosecutors argued two motives that ran together: money and another woman. Craig had filed for bankruptcy in 2021 and, according to the arrest affidavit, was “on the verge of bankruptcy again.” He was the sole beneficiary of four life insurance policies on Angela worth a combined $4 million.
He had also begun a relationship with Dr. Karin Cain, a Texas orthodontist he met at a dental conference at the Bellagio in Las Vegas in late February 2023. In three weeks the two exchanged nearly 4,000 text messages. Craig told Cain he was already divorcing Angela and living in a separate apartment. Neither was true. While Angela lay dying, he bought Cain a plane ticket to Colorado.
The texts read at trial showed his state of mind. On February 28 he wrote to Cain, “I’m glad she’s leaving town tomorrow so we won’t have to interact for a while. Maybe she will decide to stay gone for a long time… it would make my life easier.” As Angela grew sicker and began voicing suspicion, Craig recast her accusations to Cain: “I’m undergoing an onslaught of how I must have poisoned [Angela] right now.” He told Cain his wife was “trying her hardest to die” and had previously attempted suicide by stealing sedatives from his office. Dr. Lear testified there was no record of suicidal ideation in Angela’s medical history.
Cain took the stand for about three hours and was seen crying as her messages with Craig were read. She told jurors she now views the relationship with “pity and disgust and just disbelief.”
The Jailhouse Plots
Craig’s conduct in custody produced five more felony charges. In November 2024, roughly two weeks before his original trial date, he tried to enlist his cellmate at Arapahoe County Jail, Nathanial Harris, to derail the case. Testimony at trial described Craig offering $20,000 to have Detective Olson killed, calling her “the worst, dirtiest detective in the world” and telling Harris there was a “blank check involved.” He also offered $20,000 each to people willing to testify falsely that Angela had killed herself, and he tried to intimidate a sheriff’s deputy by having Harris photograph the deputy’s son.
Harris’s wife called the Arapahoe County Sheriff’s Office. On November 10, 2024, detention supervisor Nicholas Hudson searched the shared cell and recovered an 11-page handwritten letter signed “Jimmy Craig” that laid out the schemes and instructed that if the fabricated story could not be delivered to the district attorney, it should be taken to the media.
Craig also mailed his 20-year-old daughter a handwritten letter with step-by-step instructions for making a deepfake video of Angela in which she would appear to request the poisons herself. He told her to buy a cheap laptop with a prepaid Visa gift card, use the dark web to find the software, backdate the video, burn it to thumb drives, plant them in Angela’s bag for investigators to find, and destroy the laptop. His daughter did not comply. She later testified about the letter, calling it “disappointing” and “confusing.”
On February 14, 2025, Judge Shay Whitaker found probable cause to add one count of solicitation to commit first-degree murder, two counts of solicitation to commit tampering with physical evidence, and two counts of solicitation to commit first-degree perjury.
Verdict and Sentence
The trial opened July 15, 2025, and ran twelve days. Prosecutor Michael Mauro told jurors Craig was “the person guilty of the ultimate betrayal — her murder.” Defense attorney Lisa Moses argued Angela may have died by suicide, citing 2018 journal entries about depression, and said investigators had “blinders on.” Moses conceded Craig was “completely dishonest” about his affairs but argued infidelity is not murder. The defense called no witnesses.
Jurors began deliberating the afternoon of July 29 and returned a verdict the next day. On July 30, 2025, they convicted Craig on six of seven counts:
- First-degree murder for Angela’s poisoning death.
- Solicitation to commit first-degree murder for the plot against Detective Olson.
- Two counts of solicitation to commit tampering with physical evidence.
- Two counts of solicitation to commit first-degree perjury, including the deepfake scheme.
He was acquitted on one count of manslaughter tied to causing or aiding a suicide. Judge Whitaker imposed life without the possibility of parole for the murder, plus a consecutive 33 years, the maximum on each of the five solicitation counts. Craig’s Colorado dental license, suspended on March 23, 2023, was later revoked.
About the Dateline Episode
Dateline NBC’s coverage, “Secrets of Exam Room 9,” is a two-hour episode reported by correspondent Andrea Canning that first aired Friday, September 5, 2025. Detective Olson walks Canning through the hospital security footage from Angela’s final hours, and friends of Angela describe a prayer session they later found suspicious. The episode features the work of Olson and Detective Harris, referred to as the Aurora Police Department homicide unit’s “twin detectives.” It streams on Peacock and the NBC app.
Asked after the verdict about the murder-for-hire plot that targeted her, Olson said the threat sharpened her focus. “I’m the lead detective, I’m here to give Angela justice, and you’re not going to stop me.”
