Joshua Riibe, original from Rock Rapids, Iowa, has been given his passport and was allowed to return to the United States.

Joshua Riibe's return to the U.S. remains unclear as there was no immediate decision about returning his passport, which authorities confiscated last week.

The man who is the last person known to have been with missing University of Pittsburgh student Sudiksha Konanki is on a plane heading back to the US after he obtained a new passport, a source in the prosecutor’s office told CNN Wednesday.
