Police say an Oregon man accused of killing a 3-year-old son and the mother of a child faces a child support order

The boy and his mother are missing, but the evidence "leads to a consistent conclusion that they were killed," the prosecutor said.

An Oregon man accused of killing his 3-year-old son and the child's 25-year-old mother was indicted on murder and kidnapping charges on Tuesday and will be held without bail.

Michael John Wolfe, 52, is charged with two counts of aggravated murder, one count of domestic violence murder and two counts of kidnapping, according to court documents.

His son, William "Billy" Fretwell, and the girl's mother, Karissa Alyn Fretwell, were reported missing on May 13, according to the Salem Police Department. Although the researchers have not found any bodies, they say there are possible causes to believe that Wolfe killed them.

"Without having bodies, makes the case more complicated." But I would say that, in summary, the evidence that has been gathered is leading to a consistent conclusion that they were murdered, "said Yamhill County District Attorney Brad Berry, according to NBC affiliate WDSU mother and son.

Fretwell verified through DNA tests last year that Wolfe was the father of his son, and he was recently ordered to pay $ 900 a month in child support, according to an affidavit of probable cause. A nanny told the police that Wolfe and the woman had had to be threatened with custody of the girl.

"Based on interviews with Karissa's family and friends, I believe that the only known person who will benefit from the disappearance or criminal killing of Karissa and William is Michael," the investigators said in the affidavit.
Wolfe told police she had no recent contact with Fretwell, but investigators believe they met around May 13 and have evidence showing text messages on their phones on May 14, according to the affidavit.

The surveillance video outside of Wolfe's workplace showed him walking in a wooded area and returning with a garbage bag on May 14, according to the document.

Wolfe is being held in the Yamhill County Jail
