Nicaragua’s police, army and navy will investigate the captain of a tourist boat and his assistant for the deaths of 13 Costa Rican passengers killed when the vessel capsized in bad weather, a top government official said.

The “Reina del Caribe,” Spanish for “Caribbean Queen,” was carrying 33 people when it went down Saturday amid rain and strong winds as it ferried between the Corn Islands, a popular tourist destination, off Nicaragua’s Caribbean coast.
