An Oklahoma man charged on suspicion of a 1990 sexual assault in Wisconsin and considered a person of interest in a 1992 double murder will stand trial in the Wisconsin case.
Glendon Gouker, 41, waived his right to a preliminary hearing Friday in Waupaca County.
The Post-Crescent reported an arraignment is scheduled for Feb. 27.
Gouker is accused of sexually assaulting a then-20-year-old woman in November 1990 in Iola.
The break in the case came in 2011, when evidence was resubmitted to the state crime lab for analysis as part of an investigation into the 1992 fatal stabbings of 23-year-old Tanna Togstad and 35-year-old Tim Mumbrue.
Sheriff's officials said Gouker is a "person of interest" in the homicides.
Gouker was extradited from Oklahoma, where he's charged with killing a 19-year-old man.
