Help us to find my son. Tell to send them back home.

This is what the mothers of disappeared families told us at the session of women headed families session today.
We do not have tears to cry any more. But we are still waiting them come back home. We believe they are still keeping some where.
How do we address this issue.? Hundreds of thousands of people raise this once we meet people any where in the north or east.
Why southern people do not care the tears of northern mothers? Is this not an issue we need to address collectively?
