Sheriff doubts Joshua Riibe's involvement in missing Sudiksha Konanki case, but US officials push for full investigation

Authorities do not believe Joshua Riibe is responsible for the disappearance of Sudiksha Konanki, a University of Pittsburgh student, last seen in Punta Cana. Despite gaps in Riibe's memory, he has been cooperative. Investigators are pushing for the Dominican probe to be completed. Konanki's parents request the investigation to focus elsewhere and want her declared dead. Surveillance footage reveals no conclusive evidence yet.
