Miriam Diaz, 35, was last seen on August 18, 2011, near Falfurrias, Texas. She had been traveling with a group from Veracruz, Mexico, after crossing the river near Reynosa and resting in McAllen. On August 16 the group continued on foot through difficult, remote terrain; three days into the trek Miriam was left behind near a tree with a water bottle in hand because she could not keep up. She has not been seen or heard from since.

Her disappearance fits a pattern of migrants going missing in Brooks County and other remote borderlands, where harsh conditions and dehydration make travel extremely dangerous. Advocacy groups and local authorities have worked on the case, but Miriam remains missing.

If anyone was with Miriam on that stretch of the route or remembers seeing her near Falfurrias on August 18, 2011, please share what you know.
