‘Heinous, calculated’: Colorado dentist arrested in connection to wife’s murder by poisoning

Investigators arrest James Toliver Craig following evidence he arranged for a canister of potassium cyanide to be sent to his office

In what authorities have called a heinous, complex and calculated murder", a dentist from the Denver area is facing accusations that he poisoned his wife and killed her so that he could make more room in his life for his mistress.

James Toliver Craig, 45, of Aurora, Colorado, came under scrutiny after he drove his 43-year-old wife Angela Craig to a hospital on Wednesday night as she complained of severe headaches and dizziness, according to police. Her condition quickly worsened, and medical staff placed her on a machine meant to help her breathe before declaring her dead.
