Corinto, Nicaragua
In 1868, Haraszthy left California for Nicaragua. He formed a partnership with a German-born physician and surgeon named Theodore Wassmer and began to develop a large sugar plantation near the seaside port of Corinto, Nicaragua, where he planned to produce rum and sell it in American markets. On July 6, 1869, he disappeared in a river on his Nicaraguan property. Whether he fell into the river and was thereafter washed out to sea, or was dragged under the water by alligators which infested the area, was never finally established. His body was never found.
