For almost ninety years he believed he was a found child.
A DNA test showed that he had lived with the wrong name all his life.
The story begins on August 23, 1912, in Louisiana.
Little Bobby Dunbar, four years old, disappears while he is with his family near Lake Swayze.
The research is immense.
Forests are searched, dragged the lake and followed every possible runway.
But there is no trace of the child.
His disappearance becomes one of the most followed cases in the United States.
Eight months later, there's a breakthrough.
In Mississippi, the police find a child traveling with a man named William Walters.
The man claims that the child is called Bruce and that he was entrusted to him by his mother, Julia Anderson.
When the Dunbar spouses see him, they think they found Bobby.
Julia Anderson, however, shows up and strongly states that she is her son.
She is one mother, poor and without economic means to face a long legal battle.
His version is questioned.
The court decides to entrust the child to the Dunbars.
That little boy will grow up by the name of Bobby Dunbar, build a family and live his entire life convinced he is the found son.
But in the Dunbar family the doubt will never disappear completely.
Almost a century later, in 2004, a descendant agrees to undergo a DNA test.
The result completely changes history.
The man raised like Bobby Dunbar had no biological connection with the Dunbar family.
Julia Anderson said the truth.
The baby was really his son.
Bobby Dunbar, on the other hand, did not know anything.
His disappearance remains one of the most famous unresolved mysteries in American history.
This story recalls how poverty, prejudice and weight of appearances can change the fate of a person.
And as, sometimes, truth takes almost a century to find its voice.
