GRAND HAVEN TOWNSHIP, Mich. — The quiet suburban neighborhood of Riverwood is struggling to make sense of a tragedy that left eight people dead inside a two-story home. Investigators say Kristopher Karolkiewicz, 47, shot and killed his wife, Amanda “Mandy” Karolkiewicz, 39, and their six children before setting multiple fires and turning the gun on himself.
The grim discovery came Friday morning when first responders arrived at the home after neighbors reported a house fire. The bodies of the family were found in bedrooms throughout the residence, according to Ottawa County Sheriff’s Capt. Jake Sparks. Autopsies later confirmed that Amanda and the children died from gunshot wounds, and the manner of death for Kristopher was ruled suicide.
“The investigation at this point shows that this is a murder-suicide, with the fire being started after the murders,” Sparks said at a news conference Monday. He added that the fires were intentionally set in numerous places inside the home, both on the first floor and in the basement.
The six children included four boys, ages 15, 12, 11 and 5, and two 11-year-old girls who had been adopted. Their names have not been released. The couple’s cousin, Emily Jones, spoke on behalf of the family, describing Mandy as someone who “lit up every room she was in.” Mandy had recently taken her adopted daughters to China, a trip that brought her joy, but family always came first.
“Her kids were in everything she did,” Jones said.
Mandy’s parents, Steve and Becky Lawwill, issued a statement expressing their devastation. “Our daughter Mandy was a kind and devoted soul who loved her family and her students,” they said. “We treasured every moment we had with her and her six children, and words cannot adequately express our devastation. We pray for God’s peace and comfort as we grieve their deaths and honor their lives.”
Mandy worked as a substitute for Grand Haven Area Public Schools, where counselors are now being offered to students and staff. Kristopher had been employed by the American Heart Association as a national vice president of sales and marketing until earlier this month. The organization confirmed his employment ended in July, but did not explain why.
Investigators said there was no record of prior police visits to the home, and no indication of a struggle. They also found no note that would explain a motive. Sparks acknowledged that some questions may never be answered. “This is an unspeakable tragedy that we may never completely understand why it happened,” he said, “but we’ll do our best to find the answers and to honor the memory of those victims.”
The case remains open, and investigators are still reviewing documents from the home. The family’s pets also died in the fire. The community has been asked to keep the family in their thoughts and prayers.
