Mass graves with remains of migrants uncovered in Texas

Scientists have spent days exhuming the remains of unidentified migrants from a cemetery in Falfurrias, Texas

The county has been paying a funeral home to dispose of the bodies and they have evidently not been careful in how they did their job.  The point is that the migration is not without dangers when they get off the road in near desert conditions.
