The Wedding Ring (S04E09)

Tina McQuaig, a 27-year-old mother and wife, reached out to her babysitter on the evening of March 15, 2000, after finishing her shift at the hospital, to mention she would be stopping by the grocery store before heading home. That was the last communication anyone had with her. Four days later, her car was discovered, but her keys and purse were missing, suggesting she had parked and vanished. As investigators looked into McQuaig's life, they uncovered shocking secrets that left her husband and family reeling.
