Update: Couple Facing More Charges in Trooper Butterfield's Murder

Posted: Updated:

The couple accused in the murder of Michigan State Trooper Paul Butterfield is now facing more charges.

Eric Knysz and his wife, Sarah, were pulled over by Trooper Butterfield in Mason County. Eric is accused of shooting the trooper, then driving off.

Police tracked them down in Dublin, in Manistee County. That's where the new charges come from.

Eric is charged with a number of crimes, including receiving and concealing a stolen firearm, carrying a concealed weapon and assault with a dangerous weapon.

Sara is charged with unlawful driving away of a vehicle.

Transcripts of a statement made by a Michigan State Police Detective were also released on Tuesday. The documents show that Eric's mother was in the vehicle after the shooting in Mason County, a vehicle that belonged to Eric's father.

Eric's mother Tammi Spofford has not been charged in the case.

New details were also released regarding Sarah. She allegedly helped by picking up another driver and leaving the area to go steal another vehicle to help conceal the original getaway car.

Michigan State Police also revealed that Eric wielded a gun at troopers during their encounter in Manistee and that's when a trooper fired two shots, wounding Eric.

Police believe Eric shot Trooper Butterfield with a .357 magnum revolver.

Both will be back in Manistee court on October 7th.
