On April 1st, 2016, 32 year old single mother Nicole Fitts left her home ostensibly to meet with her 2 year old daughter's babysitter.  The nature of that meeting is unknown, and Nicole Fitts was never seen alive again, and her 2 year old daughter has not been seen since a month or more prior to that night.  A week later, Nicole's remains were found in a park in a shallow grave covered by a piece of plywood, but still, there was no sign of her daughter.  And to this day, Nicole's murder, and the whereabouts of her child, Arianna Fitts are still unsolved.  Where is Arianna Fitts, and who murdered her mother?
