Remembering the Father I Never Met: A 9/11 Memorial

10 years after the tragedy of 9/11, children remember the fathers they lost

Alexa Smagala, 9

Alexa is saddened by the fact that she has no pictures with her father, firefighter Stanley Smagala Jr., who died on first response to Tower 2. She's happy they share the same blond hair and blue eyes, but she struggles to revisit 9/11. "When I see the people running from the building that day, I know my dad was telling them to get out," Alexa tells PEOPLE. "Now I think he makes the sun shine."
