Oregon Man Pleads Guilty to Murdering His 3-Year-Old Son and the Boy’s Mother

A 55-year-old Oregon man pleaded guilty on Friday to murdering his son and the boy’s mother, a court staffer confirmed to Law&Crime.

The charges Michael John Wolfe pleaded guilty to committing were aggravated murder in the death of 3-year-old Billy Fretwell, and murder in the second-degree constituting domestic violence in the death of 25-year-old Karissa Alyn Fretwell.

As part of the plea deal, Wolfe will get 30 years to life for the aggravated murder charge, and 25 years to life for second-degree murder. In exchange, prosecutors will not seek the death penalty.

Sentencing is set for July 20.

Wolfe originally faced charges of aggravated murder and kidnapping. The mother and son disappeared from their apartment in West Salem, Oregon, on May 13, 2019.

“Karissa and William have been missing since May 13th when Karissa did not report for work,” the Yamhill County Sheriff’s Office said. “Karissa has sole custody of William and the two reside in West Salem.”

Mere days later, authorities identified Wolfe as a person of interest. He was arrested soon after. The victims remained missing until the following July 15, when they were found dead.

A member of the McMinnville Fire Department discovered the bodies, Yamhill District Attorney Brad Berry said in 2019. The mother and child were together in a wooded area, partially hidden by debris, he said.

Fretwell and Wolfe reportedly met while she was working for Jimmy John’s, according to The Statesman Journal. Wolfe actively pursued her even though he was already married at the time, going as far to as call the restaurant almost daily for her to deliver his food. He eventually got her a part-time job at Cascade Steel Rolling Mills, where he worked. Even so, he reportedly was not happy about her getting pregnant.

“She never knew he was married until after a couple weeks of her being pregnant,” Fretwell’s friend Megan Harper told KATU. “Then he offered to pay for an abortion.”

Karissa, who ended up working part-time jobs and attending Western Oregon University, sought child support from Wolfe. A judge issued a court order against him on May 10, 2019, just three days before mother and son went missing.

Wolfe denied at first that he had seen Karissa since a court hearing hearing on April 15, 2019, but surveillance footage showed he was near Karissa’s apartment; cell records placed her phone near his home. Wolfe was the only person to gain from Karissa and Billy’s deaths or disappearances, Salem Police Detective Anthony VanDekoppel wrote in an affidavit.
