Amanda “Mandy” Karolkiewicz and Kristopher Karolkiewicz‘s home was “full of smoke” after he killed her and their six children in an apparent murder-suicide, according to a 911 dispatch call from the incident. “White smoke coming out of the window, house is full of smoke seen from the outside and smells electrical,” a woman was heard saying in 911 audio obtained by Fox News. Police have not shared if they believe Kristopher had a motive for the murder-suicide, but resurfaced posts from Mandy’s Reddit page revealed the couple dealt with several issues. In fact, she claimed in a 2024 post that Kristopher had previously cheated on her with an intern.
