And so it starts. I have studied this and taken photos of disappeared plaques in the sidewalks of my neighborhood. Heard stories from locals and relatives of locals. Here's CNN's take on a group trying to find and identify the missing.Buenos Aires, Argentina (CNN) -- Laura Feldman was kidnapped by the Argentine military on February 18, 1978. The 18-year-old was never seen by her family again, a victim of the ruthless regime that ruled Argentina from 1976 to 1983. For 31 years, her sister Ana searched for answers -- and her remains.
"Laura was politically active. She was young and had her ideals. But she didn't deserve to die," says Ana, 51.
In 2004, bones believed to be Laura's were found in a mass grave in a cemetery outside Buenos Aires. After a series of genetic tests confirmed her identity, Ana finally received her sister's bones in April 2009.
"I can now speak in the past tense: my sister was executed," says Ana. "And now that I have her remains, I can mourn her -- something her murderers tried to deny me," she says.
