A Colorado dentist was found guilty of murdering his wife in a methodical plot to poison her.

Dr. James Toliver Craig, 47, a Colorado dentist, faces life in prison without parole after being found guilty Wednesday of first-degree murder for poisoning his wife, Angela Craig. 

He was also convicted on five additional counts: two counts of solicitation to commit tampering with physical evidence, two counts of solicitation to commit perjury in the first degree, and one count of solicitation to commit first-degree murder. He was found not guilty on one lesser charge of manslaughter.

Cain said Craig claimed he was newly divorced and living in an apartment. But under cross-examination, she acknowledged that wasn’t true. 

“Yes, a lot of what the defendant told me wasn’t true,” she admitted. 

Just three days into their relationship, Craig wrote, “I’ve fallen in love with you so deeply that the list of attributes has become endless.” 

Prosecutors argued Craig’s lies and secret relationship were key to his motive.

Another woman, Carrie Hageseth, also took the stand, describing how she met Craig on the dating site Seeking.com. She said their relationship was transactional. He paid her daughter’s car bills.

During one dinner, she testified, Craig referenced the movie “The Purge,” in which there is one day when everyone can kill whomever they want without consequence.

Craig, she testified, said that if he could “purge” someone, it would be his wife. He went into detail, Hageseth testified, describing how a person could be killed via injection without consequence.

Together, the women’s accounts painted Craig as a man leading a double life. Prosecutors used the volume and tone of his communications to argue this was a calculated scheme.
