Relatives of some of Mexico's over 100,000 missing people marched through downtown Mexico City Tuesday to demand authorities find their sons, daughters, parents and siblings.

The protesters carried photos of the disappeared hanging from their necks, and chanted "Where are they? Our Children, Where are they?"
