More than 400 dead dolphins were found last month on the Pacific Ocean beaches where twice that amount were encountered in 2012, Peruvian officials said Monday. Authorities never established the cause of death in 2012. They are doing autopsies now on the dolphins found in January in the Lambayeque region on the northern coast. Technician Jaime de la Cruz of Peru's IMARPE marine life agency said about 220 dead dolphins were found the last week of January, the rest during the previous three weeks.
