A Bay Area boy was kidnapped from a park in 1951. He's just been found alive

So heartbreaking that his mother died almost 20 years ago, never knowing what happened to him. At least his brother managed to see him before he died.

&gt; For over 70 years, he lived on the East Coast believing he was the son of another couple.<p>How is that possible? He was 6 years old, he should have known who his parents were. Did he have no memories of his parents or siblings?
