'Stolen babies' raise ghosts seeking truth

Pedro Sandoval stopped celebrating Mother's Day, Father's Day and even his own birthday after he found out the truth: The mom and dad he knew growing up had stolen him from his biological parents, who were kidnapped, tortured and never heard from again during Argentina's 1976-1983 military dictatorship.

"I'm still jealous of friends who can hug or get into arguments with their parents," said Sandoval, 38, alluding to the biological parents he never met. "But I'm also thankful that I could at least hug my grandfather and grandmother."

Four decades after the ruling military government launched a systematic plan to steal babies born to political prisoners, Argentina's search for truth is increasingly focused on the 500 or so newborns whisked away and raised by surrogate families. Several hundred have yet to be accounted for.
