How did St. Maria Goretti die?

Maria was attacked by a 19-year-old farm-hand named Alessandro Serenelli. He tried to rape Maria but she fought and yelled that it was a sin and that he would go to hell. He tried to choke her into submission and then stabbed her fourteen times. She survived in hospital for two days, forgave her attacker, asked God's forgiveness of him, and died holding a crucifix and medal of Our Lady. She is counted as a martyr.
