Amanda “Mandy” Karolkiewicz wrote a children’s book that she dedicated to her six kids just three years before her husband, Kristopher Karolkiewicz, killed her and their family in an apparent murder-suicide. Kramer went on to say that Mandy “loved her children with every part of her being.” “Mandy once shared with me why she wrote the book. As Us previously reported, Kristopher, 47, killed Mandy and their six children inside of their home in Grand Haven Township, Michigan, on the morning of Friday, July 24. Authorities confirmed that Amanda and the children were fatally shot before Kristopher set the home on fire as part of an apparent murder-suicide.
