In Pursuit: The Missing

With the acute understanding of someone whose family has been through the unimaginable experience of losing a child, Callahan Walsh hosts an hour-long special spotlighting missing persons cases with In Pursuit: The Missing. As a spokesperson and child advocate for the National Center for the Missing & Exploited Children, Callahan brings his passion, empathy, and determination to actively investigate two mysterious disappearances, and provide an outlet to the families desperate for answers. The special also showcases missing children cases from around the country, each with a ticking clock, unanswered questions, and an urgent need to activate the public to come forward with tips or information that might help bring these missing persons home to their loved ones.
