Six people who were found dead following an apartment fire in Wisconsin last week were each found to have suffered a single gunshot wound, police said Monday. Connor McKisick, one of the people who was found dead, had a self-inflicted gunshot wound, police said.

"The details and context of all the other individual's wounds are still under investigation," said Hartland police chief Torin Misko." 

Misko also said that there was "evidence of an ignitable liquid in the apartment where it normally would not be located."
