THOMPSON FALLS – Nathan Lee William Calvert’s trial date scheduled for Monday, September 16th has been vacated and a change of plea has been scheduled for the following day on Tuesday, September 17th at 10 a.m.

On Monday, August 26, District Judge Kim Christopher vacated the trial, which was estimated to last a week.

Calvert originally entered a plea of not guilty to the charges facing him and public defender Steven Eschenbacher said the defendant would rely on mental disease or defects to prove he was not in an intrastate of mind at the time of the attack and lacked special intent.

Court documents revealed that Calvert said he did not know why he killed Doug Morigeau or attacked Cheryl Morigeau.

Calvert is charged with the murder of Doug Morigeau and the attempted murder of Morigeau’s wife, Cheryl in mid December of last year following a home invasion.

Calvert allegedly stabbed Doug 54 times and beat him with a rifle until the stock broke off. Cheryl was also allegedly attacked during the home invasion suffering a cut to the throat but she managed to escape the house and flee to a neighbors.

Interviews in the court affidavit revealed that Cheryl went on to describe Calvert’s eyes “as cold and evil.”

His bail after being taken into custody was set at one million dollars.

After postponing the original trial date of July 15, Calvert underwent a secondary mental evaluation at the request of Prosecutor Bob Zimmerman.

Calvert was charged with four felony counts including deliberate homicide, attempted deliberate homicide, aggravated burglary and robbery.

During the time of the attack, Calvert was allegedly high on “spice,” a synthetic drug.

After smoking the drug for almost a dozen days, Calvert claims he became paranoid , leaving the residence he was at.

He stated that he heard voices and began hallucinating while on the drug.

Calvert did not know the Morigeaus.

Zimmerman stated the state would not be seeking the death penalty in this case.

Before attacking the Morigeaus, court documents revealed that Calvert stabbed a third person before the attack.

Gordon Northpiegan was allegedly stabbed in the back after Calvert “became convinced that Northpiegan was going to kill him.”

Although Northpiegan denied to police officers that he was stabbed, he was later treated at a Polson hospital for a stab wound.
