Chilean rescue teams in boats search for the remains of the tourist boat "Rio Cholhuaco," with 32 passengers and two crew, that set out from the southern city of Osorno and sank in the Rio Negro just short of its final destination -- the Pacific port of Bahia Mansa. The Chilean navy told AFP six people were confirmed dead and one missing. Their nationalities were not divulged. The captain of the boat was arrested. Prosecutors say the boat was overladen and several passengers were not wearing a life jacket. IMAGES
