Aurora dentist James Toliver Craig was convicted on July 30, 2025, at the end of a two-week Colorado murder trial in which prosecutors proved he poisoned his wife Angela with cyanide, tetrahydrozoline, and arsenic slipped into her protein shakes over ten days in March 2023. An Arapahoe County jury found him guilty of first-degree murder and five related felonies, and District Judge Shay Whitaker sentenced him the same day to life in prison without parole plus 33 consecutive years.
How Angela Craig Died
Angela Craig, 43, first told her husband she felt “drugged” and was having vision trouble on March 6, 2023. He drove her to Parker Adventist Hospital, where she was treated and released. The symptoms came back. She was readmitted, released a second time on March 14, and admitted to University Hospital the next day. On March 15 she had a seizure after a visit from her husband and was placed on life support. She was taken off life support and died on March 18.
Arapahoe County Coroner Dr. Kelly Lear ruled the death a homicide caused by acute cyanide and tetrahydrozoline toxicity. Toxicology on blood drawn March 15 showed nearly twice the lethal amount of cyanide, along with a lethal concentration of tetrahydrozoline, the active ingredient in over-the-counter eye drops, and toxic concentrations of arsenic left from earlier exposures. Forensic toxicologist Dr. Justin Brower testified that cyanide levels rose between two draws taken hours apart on March 15, meaning a second dose was given while Angela was already hospitalized.
The Evidence Against James Craig
Investigators arrested Craig within hours of his wife’s death. The case against him was built largely on digital records showing methodical procurement of poisons in the weeks before Angela fell ill.
On February 27, 2023, Craig created a Gmail account under the alias “jimandwaffles@gmail.com” from a computer at his Summerbrook Dental Group office. That account and computer produced searches including “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,” and “how to make murder look like a heart attack.” He also researched polonium, mercury, botulinum toxin, and oleandrin.
Using the alias account, Craig ordered ten grams of crystalline arsenic metal from Amazon on February 27; it arrived at the family home on March 4. He bought 19 packages of eye drops at a King Soopers on March 8 and 9. On March 9 he ordered potassium cyanide from Midland Scientific, submitting a fraudulent usage form claiming the chemical was needed for “electroplating over medical prosthesis” and “craniofacial reconstruction” research for the National Institutes of Health. The cyanide, in a canister marked with biohazard stickers, arrived at his dental office on March 13. He also ordered oleandrin, but detectives intercepted that package before delivery.
Home security video from March 14 showed Craig preparing a protein shake for Angela. Text messages captured her telling him “I feel drugged” after drinking one. Office manager Caitlin Romero saw Craig sitting in a darkened exam room using a computer and later noticed a package labeled “Jim Craig – Personal.” When his business partner Ryan Redfearn asked about it, Craig first said it held a ring for Angela before admitting it contained potassium cyanide.
Why Prosecutors Said He Did It
Prosecutors described three “converging timelines”: Angela’s worsening illness, Craig’s poison purchases, and a new romantic relationship.
Craig met Karin Cain, a Texas orthodontist, at a dental conference in Las Vegas in February 2023. He told her he was divorcing and living in a separate apartment. Neither was true. Investigators recovered roughly 4,000 text messages between the two over about three weeks. Cain testified that while Angela was hospitalized, Craig messaged her claiming his wife was accusing him of poisoning her. Cain had planned to visit Denver March 8–10, then rescheduled to March 16–20 after Angela got sick. She was in the city when Craig was arrested.
Money was the second strand. Craig’s practice had filed for bankruptcy in 2020, and Redfearn said he was again “on the verge of bankruptcy,” with liabilities above $2 million. He held life insurance on Angela worth roughly $3.4 million to $4 million, naming himself sole beneficiary. Prosecutor Ryan Brackley told jurors the state was not required to prove a specific motive but laid out financial pressure and the affair as the driving forces, arguing Craig felt trapped and did not want the stigma of divorce.
The Defense’s Theory
Craig did not testify, and his attorneys called no witnesses. Defense lawyer Lisa Moses argued Angela had been broken by years of infidelity and asked her husband to help her end her life, citing journal entries such as “I don’t just feel sad… I feel depressed.” The defense framed Craig’s internet searches as an effort to “understand what Angela Craig was doing to herself” and attacked the investigation for “tunnel vision,” untested items, and blurry hospital footage said to show Craig with a syringe.
Prosecutors responded that there was “not one shred of evidence” of any suicide pact and pointed out that Angela had repeatedly sought emergency care to stay alive. They told the jury Craig “spent 10 days killing Angela Craig,” and noted that on March 15, as she was seizing in the hospital, he was texting Cain and taking photos.
Jailhouse Plots That Added Five Charges
Five of the six counts Craig faced at trial were added while he sat in jail awaiting trial, arising from attempts to plant evidence, silence the lead detective, and manufacture a video defense.
Former cellmate Kacy Bohannon testified that Craig asked him to break into the family home and plant forged evidence suggesting Angela was suicidal, handing him a map of the house, a list of security cameras, and the vehicle unlock code. Craig said he would “rewrite” journal entries to fit.
Another cellmate, Nathanial Harris, testified that Craig offered $20,000 to have Aurora Police Detective Bobbi Olson, the lead investigator, killed before the first trial date, calling her “out to get him.” Craig also asked Harris to photograph the son of a sheriff’s deputy getting off a school bus for “intimidation.” He wrote an eleven-page letter to Harris’s ex-wife proposing $20,000 per person to recruit witnesses who would falsely claim they had brought Olson evidence of Angela’s suicidal tendencies and been ignored, with Photoshopped documents to back it up. Harris’s wife Loretta reported the letter to Arapahoe County Sheriff’s Sgt. Nicholas Hudson in November 2024, and a cell search recovered it.
The most striking testimony came from Craig’s second-oldest daughter, then 20. She told jurors her father sent her a handwritten letter with step-by-step instructions to fabricate a deepfake video of Angela asking Craig to order the chemicals. He told her to buy a cheap laptop, use the dark web and prepaid Visa gift cards, force the file’s metadata to February 27, burn copies to thumb drives, and then claim she “found” them in her mother’s bag. He called it “The Memories Project” and set code words: “candy was good” for yes, “candy was disappointing” for no. She had received the letter after Craig manipulated her into bailing out an inmate he claimed was a cousin, and she read it aloud in a car with her older brother and uncle, who were already suspicious.
The Verdict and Sentence
After closing arguments on July 29, 2025, the jury deliberated about nine hours and returned its verdict the next day. Craig was convicted of first-degree murder, solicitation to commit first-degree murder, two counts of solicitation to commit tampering with physical evidence, and two counts of solicitation to commit perjury in the first degree. Jurors acquitted him of one count of manslaughter tied to “cause or aid suicide,” rejecting the defense theory. Second-degree murder, criminally negligent homicide, and manslaughter were available as lesser options in the jury instructions; jurors chose the top charge.
Judge Whitaker imposed life without parole for the murder and the maximum on each remaining count, 33 years total, all consecutive. “Dr. Craig unleashed a path of destruction as wide as a tornado, and just as devastating,” she said. Craig did not speak, and no one spoke on his behalf. District Attorney Amy Padden called the killing “deliberate” rather than a “heat of passion” act.
What Came After
The Craigs’ six children sued their father, Summerbrook Dental Group, and Midland Scientific in Jefferson County District Court. The complaint alleged the practice failed to supervise Craig and gave him the credentials and facilities he used to order the poisons, and that Midland Scientific sold an ultrahazardous chemical without adequate verification. Judge Chantel Contiguglia entered a default judgment against Craig and Summerbrook after neither responded. Midland Scientific moved to dismiss, and damages had not yet been set.
Summerbrook Dental Group closed in April 2023, a month after Craig’s arrest. At least one former patient said she had paid $40,000 for dental implants she never received.
On August 7, 2025, Judge Whitaker granted Craig’s request to appoint the Colorado State Public Defender’s Office for his appeal and allowed him to proceed without paying court costs. That office was directed to determine whether a conflict of interest would prevent it from representing him.
