An evidentiary hearing in the ongoing case of an Aurora dentist accused of poisoning his wife last year was delayed Thursday. James Craig is on trial for allegedly murdering his wife, Angela, by slipping her lethal doses of potassium cyanide and tetrahydrozoline, an ingredient commonly found in eye drops.

Earlier this week, 18th Judicial District Attorney John Kellner amended a fourth count against Craig, which which was a solicitation to commit tampering with evidence charge, to perjury. The filing indicated that the former dentist tried to get another inmate, William Walbon, to lie for him.

Craig’s attorney Harvey Steinberg argued that the motion to amend the charge was filed two days ago, which didn’t give him enough time to prepare.

Judge Shay Whitaker agreed and set a new date for the preliminary hearing on the fourth charge of perjury for Sept. 11 in Arapahoe District Court. 

According to an arrest affidavit from Aurora police, Angela Craig was rushed to a hospital three times before her death — on March 6, March 9, and March 15, 2023 — after becoming faint and dizzy. 

On the third and final hospital visit, she collapsed and never recovered, the affidavit reported.  She was put on life support later that day and died March 18. 

According to the arrest document, in text messages to a co-worker while Angela Craig’s health was being assessed, Craig wrote “If wasn’t my wife, this would be kind of a fun puzzle to work out!”

Craig later told investigators that his wife was depressed and had “suicidal ideations,” the affidavit reported. Angela Craig’s family has denied those allegations. 

Craig is facing one count of murder after deliberation, two charges of tampering with evidence, and a fourth perjury count in the death of his wife. 

Jury selection in Craig’s jury trial is scheduled to begin Nov. 21 with the actual trial starting Dec. 2.
