According to most recent reports, mountain search efforts yesterday were unsuccessful. Spokesmen for SINAPROC, Panama's agency for civil protection report international search and rescue standards are being applied, and they are asking for anyone with information to come forward. Two helicopters and 35 police units had been dispatched in search efforts. Apparently the police have upgraded the search to a criminal investigation at this time. Rumor has it the women were seen returning from a short hike on April 1st around 3:00-3:30 pm, and were waiting for a bus or taxi back into the downtown area. Other information suggests they may have been hitchhiking. A $2500 reward is being offered by the Spanish language school where the women were enrolled for information leading to their whereabouts. Six days have now passed since their disappearance. Independent search efforts reportedly continue.
