A Price man has pleaded to a reduced charge in the shotgun slaying of a police informant and has agreed to testify at the Nov. 28 trial of his co-defendant, prosecutors said Wednesday.

Stacy Ray Peterson, 20, originally charged with capital homicide in the death of Gary Webb, 31, Price, pleaded guilty Tuesday to second-degree murder.In exchange for Peterson's guilty plea, the Emery County attorney's office agreed to dismiss single counts of aggravated kidnapping and aggravated robbery, prosecutor Scott Johansen said.

Peterson, who faces five-years-to-life in prison on his guilty plea, will not be sentenced by 7th District Judge Boyd Bunnell until the case against James Dee Evans is resolved, Johansen said.

It's anticipated that he will testify at the trial of Evans, 23, Price, who faces the death penalty if convicted of capital murder, aggravated kidnapping and aggravated robbery, Johansen said.
