OSHKOSH (NBC 26) — The Winnebago County Sheriff's Department identified the three people found dead on Division Street in Winneconne as 57-year-old Jeffrey Manke and his two daughters — 16-year-old Jaelyn Manke and 11-year-old Lenora Manke.
They were found during a welfare check on the 500 block of Division Street on Friday, July 31. The Winnebago County Sheriff's department is leading the investigation.
"We extend our deepest sympathies and condolences to the families," Winneconne Police Chief Ben Sauriol said. Sauriol emphasized that incidents such as this are "exceedingly rare."
"Winneconne is small town America, and we all pretty much know everybody here. And when something like this happens in a quiet community, it sends ripples and it's shocked everybody at this point," Sauriol said.
Court records show Manke's divorce was finalized earlier in the day on July 31. Four days before Manke died, a witness was requested to appear in his divorce case to discuss his firearm collection and his health.
