Teresa Rodriguez, 23, was last seen August 31, 2010, near Falfurrias, Texas while traveling in a group from Mexico to the U.S. The day before she left, she told her sister she would begin walking the next day. During the trek Teresa became ill and fell behind; the group left her sitting under a tree by a dirt road, hoping someone would find and help her. A passerby later reported seeing a woman in that area, but when authorities, including Border Patrol, arrived the woman was gone. Teresa has not been seen or heard from since.

She was about 5 feet 2 inches and 135 pounds with brown hair when she disappeared. Searches were conducted and investigators continue to seek information that might explain what happened to her.

If anyone was in the Falfurrias area on August 30–31, 2010, or has information about the group she was traveling with, please come forward.
