A DEVIL dentist has been found guilty of slowly killing his wife with poisoned protein shakes before serving her cyanide in the hospital.

James Craig has been convicted of first-degree murder for killing his wife Angela after 20 years of marriage.

A court found that the Colorado man had poisoned Angela Craig over 10 days in March 2023.

However, when those efforts proved unsuccessful, the dentist provided his wife a last dose of cyanide while she was hospitalized with symptoms that baffled doctors, according to prosecutors.

She was declared brain dead soon after.

Toxicology reports revealed that Angela Craig, aged 43, succumbed to cyanide and tetrahydrozoline poisoning— a compound typically found in non-prescription eye drops, as per the coroner.

Photos from a hospital security camera produced in court showed Craig holding a syringe before he entered Angela’s room.

After delivering the lethal dose through her IV, Craig exited and messaged a fellow dentist with whom he was romantically involved, prosecutors stated.

Court filings revealed that Craig intended to murder his wife to escape a marriage he felt trapped in, noting he avoided a divorce to safeguard his finances and reputation.

Legal papers revealed he reportedly arranged to have her fly to Colorado when Angela was ill.

Text messages showed the pair using affectionate language.

However, Craig reportedly sent his wife affectionate messages while she was in the hospital.

He also expressed concern about Angela’s welfare.

Months later, Cain spoke out on Good Morning America and revealed she wasn’t willing to have a relationship with someone who was married.

“There’s been no planning for a future together,” she said.

Craig was also convicted of attempting to conceal the murder by persuading others to create false evidence and testimonies suggesting that Angela had taken her own life.

He requested one of her daughters to fabricate a video of her mother expressing a wish to be poisoned and tried to coerce a fellow inmate to eliminate the lead detective investigating his wife’s demise, among other activities.

The defence had suggested earlier that Angela Craig may have taken her own life and faulted police for focusing solely on Craig as a suspect.

Police branded Angela’s death a “heinous” murder and unearthed a series of Google searches allegedly made by Craig.

Court documents also revealed that Craig ordered potassium cyanide – even though he didn’t need it to carry out his job.

The man stood in a hushed courtroom on Wednesday afternoon as the jury delivered a litany of guilty verdicts.

His sentencing followed tearful testimony by Angela Craig’s relatives about the impact of losing her, including one of the couple’s six children, who cast her father as a villain.

Craig appeared to shake with tears as his oldest daughter spoke about how much she missed being able to talk to her mother about her life and how she felt betrayed by her father.

“I was supposed to be able to trust my dad; he was supposed to be my hero, and instead hell forever be the villain in my book,” Miriam Mira Meservy said.

District Judge Shay Whitaker sentenced James Craig to life without the possibility of parole.
