- Autopsy results released by the Ottawa County Sheriff's Office show Amanda Karolkiewicz, her six children, and Kristopher Karolkiewicz all died from gunshot wounds.
- Investigators have preliminarily reconstructed a sequence in which Kristopher shot his wife and children, started multiple interior fires to obscure evidence, and then killed himself.
