A Georgia teen was supposed to be home soon after spending time at a friend's house nearby. Instead, her family was left searching for answers after the 16-year-old didn't return home. In a new 20/20 interview, johnquinones speaks with Susana Morales' mother as she recalls the last texts she received from her daughter before she stopped responding. The all-new #ABC2020 'Tracking Susana' premieres this Friday (May 8) at 9/8c on ABC. Stream the next day on DisneyPlus and Hulu.
