On February 11, 2012, Kathy vanished in Houston, Texas. At first, her friends and family clung to hope, certain she would walk back through the door with an explanation for the silence. But as strange social media comments surfaced then disappeared, and whispers of vehicle tampering spread, hope tangled with fear.

Days stretched into months. Months into years.

More than a decade later, the call finally came: Kathy had been found.

It was not the closure anyone had prayed for, but it also wasn't the end.

We still want to know - who killed Kathy?
