Joshua Riibe, who was last seen with Sudiksha Konanki the night she went missing in the Dominican Republic, will return back to the U.S. on Wednesday or early Thursday.

Joshua Riibe, the 22-year-old Minnesota college student who was with University of Pittsburgh student Sudiksha Konanki the night she went missing on a spring break trip to the Dominican Republic, will receive his passport back on Thursday, a source in the prosecutor's office told ABC News.

Joshua Riibe, the last person known to see missing University of Pittsburgh student Sudiksha Konanki, has returned to the U.S. Riibe, who was previously under police supervision, was freed Tuesday after a Dominican judge ruled he was a witness and not a suspect in the woman's disappearance.

The parents of Sudiksha Konanki requested that authorities in the Dominican Republic officially declare their daughter dead about two weeks after the University of Pittsburgh student went missing in Punta Cana.
