Craig, 45, had a canister of deadly potassium cyanide delivered to his office two days before 43-year-old Angela Craig died of suspected cyanide poisoning, according to the affidavit, which contains disturbing new claims about the days before the mother of six’s murder.

Craig had searched online for “buy Oleander,” a poisonous plant, “how many grams of pure arsenic will kill a human,” and “Is Arsenic Detectable in Autopsy?” and accessed an article titled: “6 Deadly ‘Undetectable’ Poisons (and How to Detect Them),” the affidavit states, noting that a shipment of arsenic had been delivered to Craig’s house on March 4. (Craig also ordered $330 worth of oleander from a scientific research company, which was intercepted by police, it says.)
