WAUPACA - A Weyauwega man has been charged with two counts of first-degree intentional homicide in the 1992 deaths of two people in Waupaca County.
Tony G. Haase, 51, was charged Friday morning and is expected to make his initial appearance Friday afternoon in Waupaca County Circuit Court.
Haase is charged in the March 21, 1992, stabbing deaths of Tanna Togstad and Timothy Mumbrue at Togstad's home in Royalton.
Togstad, 23, had been dating Mumbrue for less than a year before they were killed. They were last seen alive in a Clintonville tavern between 11:30 p.m. and midnight March 20.
Mumbrue, 35, was stabbed multiple times and appeared to have tried to defend himself. Togstad was stabbed twice, and her dog was killed.
Recent DNA testing led to the arrest, according to the Wisconsin Department of Justice.
"This arrest happened because of investigators' unwavering pursuit of justice over the course of three decades," Attorney General Josh Kaul said in a news release. "Thank you to everyone whose commitment to this investigation made this arrest possible."
According to the criminal complaint, Haase's name came up recently in the course of the investigation by the DOJ's Division of Criminal Investigation.
Police obtained Haase's DNA at a traffic stop on July 6. On July 18, a Wisconsin State Crime Lab analyst found that the DNA was "consistent with the profile previously detected from the bodily fluids recovered from the body of Togstad," the complaint said.
DCI special agent Jay K. Yerges, who has been working on the case since 2015, and other agents interviewed Haase on Thursday at the Waupaca County Sheriff's Office.
Haase told investigators, according to the complaint, that his father and Togstad's father had been friends. He said his father had been killed in a 1977 snowmobile accident that involved Togstad's father.
Haase said that on the night of March 20, 1992, in a "drunken stupor" and thinking about the accident, he went to Togstad's home. He told investigators that he couldn't articulate why he went there but it wasn't to hurt anyone.
At Togstad's home, Haase said he got into a "scuffle" with Mumbrue. He said he didn't know if he brought a knife or there was one at the house, but while he and Mumbrue were wrestling while standing up, Haase moved his arm in a stabbing motion toward Mumbrue's chest. Haase said Mumbrue fell to the floor.
Haase said when Togstad yelled at him, he punched her in the face. He said that, at some point, Togstad started to "stir" and Haase stabbed her in the chest.
According to the complaint, Haase said throughout the interview that he had only "snippets/blurbs" of memories that he attributed to the murders. He told investigators that, when he first saw the news report of the deaths in 1992, "he was afraid he was involved."
He told investigators he didn't know why he did it. Asked why he didn't tell investigators right away, Haase said, "I didn't want it to sound like I had it planned."
