Waupaca man spent 7 of last 10 years in prison

William E. Davidson Jr., 29, Waupaca, is charged with two counts of threatening a judge and one count of threatening an officer at a mental health facility.

On June 28, Detective Sgt. Nick Traeger met with a Waupaca County judge regarding a threatening letter.

According to the criminal complaint, the judge was presiding over a felony case against Davidson. He had been charged on Sept. 23, 2021, with second-degree sexual assault of a child and child enticement, as a repeat offender.

Davidson allegedly sent a letter indicating he would assassinate one of the other judges and an officer, depending on the judge’s decision regarding his case.

On June 30, Traeger interviewed the officer at the Wisconsin Resource Center in Winnebago, where Davidson is being held in an secure psychiatric unit.

The officer said Davidson sent him and another officer threatening letters almost daily.

The officer told Traeger that “in his numerous years of working at the Wisconsin Resource Center, Davidson is one of the most dangerous people he’s ever had contact with,” the complaint says. He said he believed Davidson would either rape or kill someone if he was released back into the public.

Both of Davidson’s cases have been reassigned to Marathon County Judge Suzanne O’Neil.

Repeat offender

On April 18, 2012, Davidson was sentenced to five years in prison and 10 years of extended supervision and ordered to register as a sex offender after being convicted of four counts of second-degree sexual assault of a child and battery to an officer.

He was released on extended supervision on April 11, 2017.

On April 3, 2019, Davidson was returned to prison after his extended supervision was revoked.

On Aug. 17, 2021, Davidson was released from prison on extended supervision.

A month later, he was back in jail on a $500,000 cash bond for alleged sex crimes.

On Dec. 14, 2021, the court found Davidson incompetent to stand trial and committed him to a mental health facility.
