Investigators are trying to piece together what happened in a Michigan home that led to 47-year-old Kris Karolkiewicz shooting and killing his six children, his wife and then himself after setting the family home on fire. We know Kris recently lost his job as a Vice President with the American Heart Association, but it’s still unclear if that played a role in the unthinkable tragedy. Investigators say they found his licensed firearm near his body, and the rest of the family members shot to death in their bedrooms. While police confirmed he did not leave behind a note, investigators have seized what they call “a lot of documentation” from the home.
