In the predawn hours of July 15, 1999, 12-year-old Heather Nicole Kullorn was caring for a two-month-old infant in a Richmond Heights, Missouri, apartment when she vanished. The baby’s father, Christopher Herbert, returned about 4 a.m. to find the infant alone; significant traces of blood later confirmed to be Heather’s were found on the couch and a white floral comforter was missing. A neighbor reported seeing an unidentified man around 2 a.m. carrying a child the size of Heather with the child’s upper body wrapped in a blanket.

Investigators quickly treated the disappearance as suspicious. Evidence of methamphetamine manufacturing in the apartment led police to focus on a possible connection to drug activity and the theory that Heather may have witnessed crimes. Herbert’s account of his whereabouts changed during the investigation, and both he and Heather’s friend Dana Madden were treated as persons of interest, though no charges were filed. Heather’s mother, Christine Kullorn, advocated for answers until her death in 2017, but Heather’s whereabouts remain unknown.

Is anyone from Richmond Heights in 1999 able to share memories or information that could help resolve what happened to Heather?
