An Oklahoma man charged with a 1990 sexual assault waived his right to a preliminary hearing Friday.
According to a Wisconsin Department of Justice statement, 41-year-old Glendon Gouker was bound over for trial in Waupaca County Circuit Court on one felony charge of first-degree sexual assault of a then-20-year-old woman in November 1990 in Iola.
The statement said Gouker’s arraignment has been scheduled for Feb. 27.
Gouker is also considered a person of interest in a 1992 double murder, according to Waupaca County Sheriff Brad Hardel.
The break in the case came in 2011, when DNA evidence was resubmitted to the state crime lab for analysis as part of an ongoing investigation into the 1992 fatal stabbings of 23-year-old Tanna Togstad and 35-year-old Tim Mumbrue. State investigators said Gouker was found to be a contributor to the DNA.
