What happens to the young apprentice engineer in mark twain?

In Mark Twain's "The Adventures of Huckleberry Finn," the young apprentice engineer, Emmeline Grangerford, is revealed to have died at a very young age. Her death is used by Twain to satirize the sentimentality and superficiality of the Grangerford family, who are more concerned with romanticizing death than truly mourning Emmeline's passing.
