I'm so confused.  I thought a DNA test was run in the first or second episode.  Jason intercepted the results, didn't show them to Nikki, and told her they showed Keith was their son.  Did I dream that?  Nobody referred to that test ever again, even when Jason sees C's reconstruction of the body found in the lake.

Same case covered in Cold Case Files (2) 20170227 "Little Girl Lost"

Agreed.
