There has to be relatives of this little girl out there they can run that DNA from the girl they found. Why don't they do that?

Cherie Nicole Barnes was two years old when she was last seen on January 7, 1987, in Kansas City, Missouri. A biracial child with brown hair and brown eyes, Cherie had moved with her mother Elizabeth Ann Turek Vasser (known as Sissy) and stepfather Larry Vasser from Nashville to St. Louis in the fall of 1986. Her mother had gone missing from St. Louis on December 1, 1986; Elizabeth’s remains were recovered from the Mississippi River in February 1987 and later identified in 1994, at which point authorities reopened the search for Cherie.

Investigators eventually located stepfather Larry Vasser in the mid-1990s while he was incarcerated on unrelated robbery and burglary charges. Vasser has told authorities he knows where Cherie is and has claimed she is alive, living under a new name with his family in the Kansas City area, but he has refused to provide a location. He once offered to give the child’s maternal grandmother photos and a voice recording for $500. Custody had been intended for Elizabeth’s relatives after her death; Cherie’s whereabouts remain unknown and the case is classified as a non-family abduction.

Does anyone have information about Cherie Barnes, her movements in Kansas City in January 1987, or contacts connected to the Vasser family at that time?
