The mother of Eric Knysz, the man convicted of killing State Police Trooper Paul Butterfield, has pleaded no contest to an accessory charge.
Tammi Spofford appeared in the Mason County Circuit Court Tuesday afternoon where she entered her plea of no contest to the charge of accessory after the fact.
A no contest plea is not an admission of guilt, but is treated as such for sentencing purposes.
Sentencing is scheduled for June 17.
Eric Knysz was convicted in the murder of Trooper Butterfield in early April. Two weeks later, he committed suicide in his cell at the Jackson Correctional Facility.
