SAN ANTONIO -- Several hundred silent marchers showed up at Hemisfair Park Saturday morning to take a stand against human trafficking.
The group "A-21" has a goal of abolishing injustice in the 21st century.
They said the local event was part of worldwide series of Walks for Freedom on this day.
Many people who participated this morning taped their mouths shut to draw attention to the victims of slavery who have no voice.
