In 1971, 21-month-old Melissa was abducted from her apartment in Fort Worth, Texas by her babysitter.
Her mother, Alta Apantenco, was only 21 at the time and continued to search for her daughter for nearly 50 years.
The family's perseverance paid off when they created a profile on a platform specializing in DNA testing.
And there is the revelation: a genetic profile indicates that the dad of the missing little girl would have an unknown grandson.
What if it was his daughter's son, Mr Highsmith wonders?
