Glendon C. Gouker extradited from Oklahoma to face charge of First Degree Sexual Assault in Waupaca County; Information still being sought in March 1992 double murder.

 

MADISON — As part of a joint, cold case investigation into a 1992 double homicide, Waupaca County Sheriff Brad Hardel and Attorney General J.B. Van Hollen announce the arrest of a former Wisconsin man, Glendon C. Gouker (DOB 04/20/71), on a charge of First Degree Sexual Assault for an incident occurring on November 5, 1990.  A news conference with Sheriff Brad Hardel is scheduled for noon today at the Waupaca County Courthouse, located at 811 Harding St., in Waupaca.  Media should report to the County Boardroom at the courthouse for the news conference. 

 

According to the Criminal Complaint, on the evening of November 5, 1990, the suspect, while wearing a mask, forcefully took a 20-year-old woman to Taylor Field Park in the Village of Iola, where he had sexual contact with her, against her will, and threatened her.  Gouker said to the victim, according to the complaint, “I’m just doing my job; I got paid to do this.”  A September 2011 report from the Wisconsin State Crime Lab on DNA analysis of evidence re-submitted to the Lab from the sexual assault evidence collection kit indicates Gouker as a contributor to DNA found in the kit.

 

Gouker, who’s currently incarcerated in Oklahoma and awaiting trial, has been charged in Waupaca County with one count of First Degree Sexual Assault -- Concealing Identity, a felony.  An initial appearance in Waupaca County is scheduled for February 7, 2013.  Department of Justice Assistant Attorney General Jeffrey Gabrysiak is serving as special prosecutor in this matter.  A copy of the criminal complaint and photo of Gouker are available at the following links:

A criminal complaint is a document accusing a person of a violation of criminal law.  A defendant enjoys a presumption of innocence.  The prosecution must prove its allegations at trial beyond a reasonable doubt.

 

The Waupaca County Sheriff’s Department and the Department of Justice (DOJ) – Division of Criminal Investigation (DCI) continue to actively investigate and seek information in the March 22, 1992, double homicide of 23-year-old Tanna Togstad and 35-year-old Tim Mumbrue.  Togstad, who also was sexually assaulted, and Mumbrue were stabbed to death in Togstad’s farmhouse.  Gouker has been identified as a person of interest in this homicide investigation; however, investigators believe there are individuals still residing in the area with knowledge about this crime. Waupaca County Crime Stoppers will have a billboard located along Highway 10 outside of Waupaca, to encourage people with information to come forward.  An image of the billboard is available here.

 

“The killer, or killers, of this couple left evidence behind when they entered Togstad’s home and savagely murdered the victims.  We’re now looking to the community for tips to help us identify a match to the DNA left at the crime scene,” Sheriff Hardel said.  “With advances in DNA technology, we hope to bring justice for the families of these two young people.”

 

Anyone with information about this case should contact the Waupaca County Sheriff’s Department at (715) 258-4466, or the Division of Criminal Investigation at (608) 266-1671.
