Lauren McIntyre, 9

Lauren wears a picture of her father, Donald McIntyre, on a pendant around her neck every day. While picking up an extra shift to make money before Lauren's birth, 38-year-old McIntyre died on duty as a Port Authority Police officer in Tower 2. Lauren understands the weight of her father's actions, her mom Jeannine tells PEOPLE: "Lauren will always say, 'My daddy died a hero.'"
