Homicide probe leads to sexual assault charges
DNA resurrects cold case
Authorities said a cold case investigation into a Waupaca County double homicide 21 years ago has led to charges in a 1990 sexual assault.
Glendon Gouker is charged with sexually assaulting a woman in Iola in November 1990. The state Department of Justice says DNA evidence from the assault was resubmitted to the State Crime Lab and Gouker was found to be a contributor to the DNA.
State and local authorities said the 41-year-old Gouker is incarcerated in Oklahoma and is a person of interest in a 1992 fatal stabbings of 23-year-old Tanna Togstad and 35-year-old Tim Mumbrue.
Waupaca County Sheriff Brad Hardel said Monday the two cases are similar but didn't specify how.
A message left for Gouker's attorney in Norman, Okla., was not immediately returned.
