Oops! Our bad. From CNN:

A Dallas teenager who ran away from home more than a year ago somehow wound up deported to Colombia after U.S. authorities mistook the girl, who lacked identification, for a Colombian national.

Now her family is demanding to know why immigration authorities deported the teen -- a U.S. citizen with no knowledge of Spanish -- and why they simply took her at her word when she gave them a fake name.

ICE is investigating, but this is not exactly an isolated incident. There have been numerous other examples of citizen kids and mentally disabled adults who end up deported.
