MCMINNVILLE, OR (KPTV) – FOX 12 was contacted Friday by a man who says he used to work security at Cascade Steel Rolling Mills in McMinnville, where he says Michael John Wolfe was his direct supervisor.

Wolfe is a murder suspect in connection with the disappearance of a Salem woman and her 3-year-old son.

Police previously said Wolfe, 52, of Gaston, was a person of interest in the search for Karissa Fretwell, 25, and her son William “Billy” Fretwell. The mother and son were reported missing last week. Court documents state Wolfe is William’s biological father.

The man FOX 12 spoke with Friday says he worked with Wolfe two or three years ago, and when he saw Wolf’s face as a person of interest in Karissa’s disappearance, he called police.

The man asked FOX 12 not to show his face because he works in a small industry.

“Even in my line of work, he was a little odder than the rest,” the man said. “It was his demeanor, a little, you know, self-absorbed…just the way he dealt with people was kind of short, he was always right, even if he was wrong.”

The man says he remembers Wolfe previously talking about how to dispose of evidence in a furnace.

"That was the first thing I thought this morning, was oh, he had talked about how to dispose of evidence," the man said. "And he had the means. We're talking weapons, IDs, cell phones. Those kind of things things could get dropped in one of those vats and no one would ever know and it's 4,000 degrees. That's vaporized when it hits."

The man says police called him back within minutes. He says that even though Wolfe’s comments were made years ago, he still thought it was a piece of the puzzle that investigators should be aware of.
