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.

A judge in the Dominican Republic ruled on Tuesday a Minnesota college student, who is presumed to be the last person to see missing Pitt student Sudiksha Konanki alive, should be freed from police surveillance.
