When he was a little boy, Lt. Dennis Mojica ran to the windows every time he heard the firetrucks. All he wanted to do was be a New York City firefighter, his sister said. And for 29 years, he was. "He loved his job--the rescues, the camaraderie with the guys, working together, helping people," said sister Judith Mojica. "Anything he could do for somebody to help out, save somebody, he was there." The 50-year-old Brooklyn man was on duty when the first plane hit the World Trade Center. Five days later, rescue workers from his firehouse found Mojica's body in the rubble. "We got him back, not the way we wanted him, but we got an answer," his sister said. "We're fortunate."
