WAUPACA, Wisc (WSAU) A former Waupaca County man suspected of raping a woman in 1990, and possibly being involved in a double murder two years later, will stay in jail without bond. 41-year-old Glendon Gouker made his first court appearance yesterday on a new charge of first-degree sexual assault with a dangerous weapon. Cold case investigators said Gouker’s D-N-A was linked to the sexual attack of a woman at a park in Iola in 1990.
Authorities said Gouker could also be connected to the slayings of 23-year-old Tanna Togstad and 35-year-old Tim Mumbrue in 1992 at Togstad’s home in Weyauwega. Gouker is due back in court a week from today on the sexual assault charge. A judge will decide if there’s enough evidence to send the case to a possible trial. Waupaca County Sheriff Brad Hardel asked for public tips on Monday about the killings. He said he has received numerous tips, and they’re all being checked on.
Gouker was recently extradited to Wisconsin from Oklahoma, where he had moved in 1993. Officials say he’s awaiting trial there for the murder of a 19-year-old man, and the kidnapping and rape of the man’s girlfriend.
