On October 21, 2022, in the early morning hours, firefighters responding to an apartment fire in Hartland, Wisconsin, discovered the bodies of six family members in a four-unit building near Oxford Drive and Mansfield Circle. All six died from a single gunshot wound. Police identified the adults as Connor McKisick and Jessica McKisick; the children included 14-year-old Natalie Kleemeier, 12-year-old Sofina Kleemeier, and two 3-year-old boys. The investigation focused on a murder-suicide, with Connor McKisick's wound determined to be self-inflicted. An ignitable liquid was found in an area where it would not normally be, suggesting the fire was set deliberately, apparently to cover up the murders. Several guns were found in the property.

The WISN article states that "the 6 people whose bodies were found after an apartment fire Friday morning all died from a single gunshot wound" and the investigation focuses on a murder-suicide, with Connor McKisick's wound being self-inflicted. This means the child was shot (inflicted injury) by the perpetrator.

Individuals Involved
Was an adoptive parent or guardian involved in the death?
Was a biological father involved in the death?
Was a biological mother involved in the death?
Was a day care worker, babysitter, or nanny involved in the death?
Was a female paramour or friend involved in the death (e.g., girlfriend, stepmother)?
Was a foster parent involved in the death?
Was a male paramour or friend involved in the death (e.g., boyfriend, stepfather)?
The perpetrator in the murder-suicide was Connor McKisick, whose wound was self-inflicted per the WISN article. The 14-year-old girl was identified as Natalie Kleemeier (different surname from McKisick), while both adults shared the surname McKisick. The FOX6 article states "all six were members of the same family." The different last name between the child (Kleemeier) and the male adult (McKisick) strongly implies Connor McKisick was a stepfather or male partner of Jessica McKisick (likely Natalie's biological mother), rather than Natalie's biological father. Thus, a male paramour or stepfather was involved in the death.
Was another adult relative involved in the death? (e.g., grandfather, aunt)
Was a sibling involved in the death?

Notable Details
The WISN article notes that "an 'ignitable liquid' was discovered in an area it wouldn't normally be found," strongly suggesting the perpetrator set the apartment fire deliberately, likely to conceal the murders. The fire is what led to the discovery of the bodies. Additionally, the FOX6 article reports that "15 fire departments and nine police departments responded," indicating the massive scale of the emergency response. Three other families in the four-unit building were also displaced. These details indicate the perpetrator attempted arson as part of the murder-suicide, endangering additional lives beyond the six victims.
