Suspect's Mom to Testify in State Trooper's Murder

By  | 

The mother of a man accused of fatally shooting a Michigan state trooper has agreed to stand trial as an accessory in his escape.
Fifty-year-old Tammi Lynne Spofford waived her probable-cause hearing Wednesday in Mason County District Court in Ludington. She's charges with being an accessory after the fact to Trooper Paul Butterfield's killing and to auto theft.
Both carry up to five years in prison. Her first hearing in Mason County Circuit Court remains to be scheduled.
Eric Knysz awaits trial on charges of murder of a peace officer. Authorities say he shot Butterfield during a traffic stop Sept. 9 in Mason County.
Knysz's wife has pleaded guilty to being an accessory and has agreed to testify against her husband.
