Prosecutors said the argument began after Lukas Rosch arrived at an Okauchee-area apartment with chicken he planned to cook.
OKAUCHEE, WI — A 27-year-old Wisconsin woman was charged Monday with first-degree intentional homicide after prosecutors said she fatally stabbed her boyfriend during a Friday night argument over dinner plans.
Mikayla R. Kloth, of the Okauchee area, made her first court appearance in Waukesha County after the death of 25-year-old Lukas Rosch. The case has drawn attention because investigators say the fight began over whether the couple would go out or cook at Kloth’s apartment. A court commissioner set Kloth’s cash bond at $2 million, and a preliminary hearing was scheduled for May 29.
Police were called Friday, April 24, to an apartment on Wisconsin Avenue in the Village of Lac La Belle, a small Waukesha County community near Okauchee. Officers found Rosch with a stab wound to the chest, according to prosecutors. He was taken to a hospital, where he died. Kloth was still in the apartment when officers arrived. Prosecutors said she told an officer at the scene that she had stabbed Rosch because she was angry at him. During Monday’s hearing, Waukesha County Court Commissioner David Herring said Kloth did not hesitate when speaking with officers. “She admits, ‘I stabbed him,’” Herring said in court, according to local reports from the hearing.
The criminal complaint says Rosch had come to Kloth’s apartment with chicken drumsticks, seasoning and plans to use an air fryer. Kloth told investigators she had not wanted him to come over for dinner and instead wanted to go out, prosecutors said. The complaint says Kloth told police Rosch was “pushing her buttons,” that she became upset and that an argument followed. Investigators said Kloth described Rosch grabbing a knife by the blade side and asking whether she wanted him to cut himself. Kloth said she got angry and pushed the knife into his chest, according to the complaint. Authorities have not said that any other person was injured. The full sequence of movements inside the apartment remains part of the pending court case.
Rosch’s family identified him publicly and described him as a loving son, brother, uncle and dog owner. In a statement shared with a Milwaukee television station, his parents and sister said they were “completely broken” by the loss of their only son, Lukas John Rosch. His father, Matthew Rosch, also spoke during the court appearance and urged the court to keep Kloth in custody. “Please never let that monster walk the streets ever again,” he said. The family said it was still processing what happened. Prosecutors said Rosch was from Delafield, another Waukesha County community west of Milwaukee.
The complaint also points to concerns raised before the fatal stabbing. Prosecutors said that about a week before Rosch died, he told another woman and the apartment landlord that Kloth had bitten his thumb. The woman told investigators Rosch seemed afraid of Kloth, according to the complaint. Rosch also gave his full name and said it should be used if something ever happened to him, prosecutors said. Those statements are now part of the prosecution’s account, but Kloth has not been convicted. The charge filed Monday is an accusation, and the case must still move through Waukesha County Circuit Court.
First-degree intentional homicide is Wisconsin’s most serious homicide charge. At this early stage, prosecutors must show probable cause for the case to continue toward trial. The May 29 preliminary hearing is expected to focus on whether enough evidence exists to bind the case over for further proceedings. Kloth may also return to court for future bond, arraignment or scheduling matters if the case advances. Court records cited in local reports list the cash bond at $2 million. It was not immediately clear from the available reports whether Kloth had retained an attorney or whether a plea had been entered.
The stabbing happened in the Village of Lac La Belle, an incorporated village in Waukesha County near Okauchee Lake. The area is a quiet lakeside community, and the apartment scene stood out sharply from its usual pace. Local police and prosecutors have framed the case around the domestic relationship between Kloth and Rosch and the argument described in the complaint. Investigators said Kloth made several statements after her arrest, including comments that she should have gone to a bar and that the situation had been irritating. Prosecutors also said she told officers that if Rosch’s parents did not hate her before, they would hate her now.
The case remained pending Tuesday, with Kloth held on the $2 million cash bond. The next scheduled milestone is the May 29 preliminary hearing in Waukesha County Circuit Court, where prosecutors are expected to outline the evidence behind the homicide charge.
