This name was used as the pseudonym for the murdered child Precious Doe in Kansas City. The name was chosen by activists in the Kansas City African-American community to point out their belief that Black children are just as Precious as those of other races, and that missing and murdered Black children deserve as much publicity about their cases as White children get.
This is the name of the creepy little poodle-dog owned by psychotic serial killer Buffalo Bill in the book and movie Silence of the Lambs. Eek. Not a good association.
