(Hartland, WI) — The investigation into last Friday’s fire in Hartland is now a murder investigation. Hartland Police Chief Torin Misko yesterday said the two adults and four kids found inside the apartment that burned had all been shot. The chief said Connor McKisick, the dad and stepdad to the kids, died from a self-inflicted gunshot wound. Investigators say it appears that McKisick started the fire just before shooting himself. The chief says the ‘context’ of the murders and McKisick’s suicide remain under investigation, but he doesn’t see anyone else being arrested in the case.
