Michigan Murder Suicide Wife's Reddit Detailed Husband's 'Shattering' Affair ...2 Years Before He Killed Family Published July 29, 2026 12:45 PM PDT The Michigan wife whom cops say was murdered by her husband Kristopher Karolkiewicz along with their six kids -- detailed his "shattering" affair 2 years before the shocking killing. TMZ uncovered many of what appear to be Amanda "Mandy" Karolkiewicz's Reddit posts from 2 years before her murder ... and she was active on threads relating to affairs and healing marriages post-cheating. In one of the posts, Mandy spoke about how learning of her husband's affair would have life-long affects on her. The post reads ... "My husband had an EA 4.5 years ago (I still suspect it was more physical than he’s ever admitted to), and I still have major triggers from time to time. Day to day we’re great, but when I get triggered, it’s shattering." The post continues, "We recently started marriage counseling, and our therapist had to make it clear to him that YEARS from now, DECADES from now, I will get triggered, because that’s how trauma works." As we previously reported, Amanda accused Kristopher of having an affair with a much-younger intern several years back ... but she decided to stick by him and work on their marriage. Amanda and Kristopher had 6 children together ... and the entire family was found dead in their home last Friday. Cops believe Kristopher gunned down everyone and then started a fire in their home before killing himself. The investigation into the brutal scene is still ongoing. Amanda was 39, and their kids were between the ages of 5 and 15. Related articles Kristopher Karolkiewicz Amanda "Mandy" Karolkiewicz RIP Murder-Suicide Crime Exclusive News
