A Colorado dentist charged with poisoning his wife bought his mistress an airline ticket to fly from her home in Austin, Texas, to be with him in Denver while his wife was dying in a hospital, an arrest warrant says.

James Toliver Craig, 45, has been charged with first-degree murder for allegedly poisoning his wife multiple times before she died on March 15. An arrest warrant obtained by Inside Edition shows that while Craig’s wife was on life support, he purchased an airline ticket from Austin to Denver for his mistress, an orthodontist. Text messages and emails between the two were also included in the warrant.

“Hi, honey. I am so sorry for what has transpired this week in your world,” the alleged mistress, Dr. Karin Cain, wrote, according to the arrest warrant. “I am sorry I am not a part of your world to be of more help to you. I love you.”

The arrest warrant also showed that Craig allegedly tried to poison his wife at least once before she died. On March 6, police alleged, Craig put arsenic in his wife’s protein smoothie that he made for her after the couple worked out.

The warrant says the wife felt faint and dizzy after drinking the smoothie and that Craig took her to the hospital. She was treated and quickly released.

A staff member at Craig’s dental office in Aurora reportedly told police that her boss had been acting strange and had used the computer in the exam room instead of the one in his office or his laptop. He allegedly told her he had a package coming to the office and that she shouldn’t open it. Craig also told her he didn’t think his wife was going to “make it,” according to the warrant.

The staff member told police that she found the package on March 13 and that it contained potassium cyanide, Buzzfeed reported. Because the dentist’s office had never ordered this before, she researched the drug and found that it caused the same symptoms Craig’s wife had experienced. The staff member said that the day after she did the research, Craig told her his wife had accused him of poisoning her. One day after that, Craig’s wife returned to the hospital with the same symptoms – and this time she died.

The arrest warrant said Craig had asked his wife for a divorce and had cheated on her multiple times during their marriage, including while his wife was in the hospital. Police searched Craig’s home the day after his wife died and found that he had created a new Google account on February 27, which he used to research poison.


Police said he searched for chemical suppliers in Aurora and even searched the phrase “how many grams of pure arsenic will kill a human.” He also searched YouTube for “Top 5 Undetectable Poisons That Show No Signs of Foul Play,” “how to make poison,” and “The Top 10 Deadliest Plants (They Can Kill You),” Buzzfeed reported.

“When the suspicious details of this case came to light, our team of officers and homicide detectives tirelessly worked to uncover the truth behind the victim’s sudden illness and death,” Division Chief Mark Hildebrand said in a statement. “It was quickly discovered this was in fact a heinous, complex and calculated murder. I am very proud of our Major Crimes Homicide Unit’s hard work in solving this case and pursuing justice for the victim.”
