The investigation began after the bodies of Paityn Decker (9), Evelyn Decker (8), and Olivia Decker (5) were discovered on June 2 near the Rock Island Campground, just days after a scheduled visitation with their father.

Authorities said the children had last been seen with Travis on May 30, and their tragic deaths have now been officially ruled as homicides by suffocation, following autopsy reports.
