On Thursday, November 10, 2022 at about 2:00 PM, deputies with the Jackson County Sheriff’s
Office responded to a residence located at W11214 Mavis Lane, in the Town of Manchester,
Jackson County, Wisconsin, to check on the welfare of the resident. Upon responding, deputies
located two deceased subjects inside the residence.

The two deceased male parties have been identified as WILLIAM KERR (78 years old), and
DANIEL ZILLMER (72 years old), both of Black River Falls. Autopsies were performed on
both parties at the Midwest Medical Examiner’s Office in Ramsey, MN. Preliminary results from
the autopsies show Zillmer died as a result of two gunshot wounds. Additional evidence from the
autopsy and the scene indicates that Kerr died from one self-inflicted gunshot wound.

Considering all of the facts and evidence collected over the course of the investigation, the
Jackson County Sheriff’s Office has determined that this incident was a murder/suicide. This was
an isolated incident and there is no present danger to the community.
