Elvia Cruz Pérez, 36, was last seen in McAllen, Texas, on June 23, 2011, while attempting to reach Houston. Originally from Mexico, she crossed into Texas via Reynosa, Tamaulipas, with the assistance of a guide.

Her disappearance underscores the risks faced by people using immigration routes along the Texas–Mexico border. Despite searches and inquiries, authorities have not developed significant leads that explain what happened to Elvia, and she remains missing. The transient nature of border crossings and the involvement of guides have complicated efforts to locate her.

If anyone knew Elvia, saw her in McAllen around June 23, 2011, or has information about guides operating between Reynosa and Texas at that time, please come forward.
