Responding officers entered the residence and located an adult male, an adult female, and two juveniles deceased in the residence with gunshot wounds. A third juvenile was located alive in the residence with a gunshot wound and was immediately transported to an area hospital for treatment. No other subjects were located in the residence.
The adult female and three juveniles were related as mother and children and all resided at the residence. The adult male was not related to the victims, resided at the residence, and had been involved in a long term relationship with the mother.

A note from police. This remains an active investigation. Protecting the integrity of the investigation, the surviving victim, and the dignity of those directly involved continues to be the priority. The West Bend Police Department is, however, aware of the significant and compelling public interest in this investigation. The following update is being provided to satisfy the balance of these protections with the community’s right to be informed
November 10, 2026 – West Bend, Wi – A memorial for a woman and two children found dead in a home has doubled in size since the incident was uncovered Saturday, November 7, 2026 in West Bend, Wi. Flowers, candy, stuffed animals and balloons line the side of a grassey hill on Wisconsin Street. The gifts serve as recognition of a tragic event that has left the small community numb and confused, as many still try to wrap their head around exactly what happened in the home at 125 E. Washington Street.
There are three wooden hearts outside the home with black markers for people to leave a note of support. Inside the blue heart is a symbol of a fish that carries Psalm 34:18 – “The Lord is near to the brokenhearted and saves the crushed spirit.” Inside the fish symbol are the words, “This area reserved for boy’s name.” The other two read, “This area reserved for girl’s name” and “This area reserved for woman’s name.”
Some of the notes include, “We will carry you in our hearts forever” and “My thoughts and prayers are with you.”
Behind the hearts the grass is lined with stuffed toy bears and dogs. Flowers are wrapped in clear cellophane and shiny mylar balloons swing in the wind and bounce off the yellow police tape that’s strung through the tree line.
Another child that was in the home on Saturday, was taken to Children’s Hospital in Milwaukee. While her status hasn’t been confirmed, sources say she is in stable condition.
While there were four people found dead inside the home, there is no fourth heart. On Monday evening West Bend Police released the name of the man found at the scene. David Slawnikowski, 54.
On a background note, a record check shows in 1995 Slawnikowski married Jennifer Marx. The couple divorced in 2008. Slawnikowski was a former Milwaukee Police Officer 14 years ago. Records show Slawnikowski lived in the city of Milwaukee and in Wylie, Texas.
West Bend Police confirm a firearm believed to be involved in the incident was recovered inside the residence. Police are also discussing domestic violence possibly being tied to this incident.
During the Saturday press conference, Lt. Brian McAndrews noted, “Domestic violence, help is available. Contact Friends Inc at (262) 334-5598.”
For informational purposes, the Wisconsin Circuit Court System now has an online restraining order portal.
The new online restraining order portal can help you generate standard court forms and electronically file a petition for domestic abuse or harassment restraining order. You will be asked a series of questions in an interview, and your answers will automatically be entered on the three documents needed to file: a restraining order petition, confidential address form, and information to assist the sheriff with service.
