PUNTA CANA, Dominican Republic – Authorities investigating the disappearance of Sudiksha Konanki are expanding their search effort as Thursday marks one week since the 20-year-old University of Pittsburgh junior vanished from a Punta Cana resort.

Her whereabouts remain unknown, and officials say they are working a missing persons case and not a criminal investigation, but they have left open all possibilities.

The Dominican Republic’s top prosecutor said Wednesday that her office is considering the possibility that something “beyond a possible accidental event” has taken place, and experts say the probe will likely examine competing theories until investigators come up with answers.

Authorities are now searching additional neighboring beaches as well as on land with 300 officers, search dogs, boats, two helicopters and other resources, Fox News Digital has confirmed. Other assets include both navy and local divers, drones and a topographical aircraft.

Reynoso’s office said late Wednesday that the search had expanded up the coast into neighboring beaches, Uvero Alto-Macao, Macao-Playa Arena Gorda, and Cortecito-Playa Arena Gorda. Civil Defense forces and firefighters have joined the effort.

Police have spent days searching the coastline with boats, dive teams and helicopters.
