According to a news release from Wisconsin Attorney General’s office, Tony G. Haase, 51, was charged with two counts of first-degree intentional homicide for the deaths of Timothy W. Mumbrue and Tanna M Togstad.

Mumbrue and Togstad were both found dead on March 21, 1992, with stab wounds in Togstad’s home in Weyauwega, Wisconsin, according to the AG’s office. A dog was also found dead with stab wounds. The Wisconsin Department of Justice Division of Criminal Investigation has been investigating the case over the last 30 years and recent DNA testing led to Haase’s arrest.

According to The Associated Press, per the criminal complaint, Togstad’s father was involved in a snowmobile accident in 1977 that killed Haase’s father.

The AP said that officers took a DNA sample from Haase on July 6 for a traffic stop and that DNA matched a sample found on Togstad’s body.

Haase allegedly told investigators that on the night of the double murder, he had allegedly gotten drunk and started thinking about the snowmobile accident, according to the AP. He went over to Togstad’s house, fought with Mumbrue and then allegedly punched Togstad. Togstad was knocked out. He then allegedly told investigators that he had stabbed Mumbrue’s chest and then Togstad when she came to.

“This arrest happened because of investigators’ unwavering pursuit of justice over the course of three decades,” said Attorney General Josh Kaul in a news release. “Thank you to everyone whose commitment to this investigation made this arrest possible.”

According to the AP, the bond was set for Haase by a judge at $2 million.
