CBS Detroit reports Eric Knysz has been charged with murdering a peace officer, felony firearm, concealed weapons violation, unlawfully driving away an auto and being a habitual offender.

His 21-year-old wife Sarah Knysz, who is reportedly six months pregnant, was charged with being an accessory after the fact and stealing a car.

Charges against the pair were filed Wednesday in Mason County District Court.

Trooper Paul Butterfield was fatally shot in the head Monday night during a traffic stop in Sherman Township, about 80 miles north of Grand Rapids.

The suspects were found based on information the fallen officer had provided on the vehicle when he stopped them.

Butterfield had joined the force in 1999 and was also an Army veteran.

Magistrate Patricia Baker says Sarah Knysz is due in court Wednesday. Eric Knysz was injured while exchanging gunfire with police. 

He is in a hospital but is expected to appear in court Thursday.
