Transcript for Hero Firefighter Captain Dern Climbing His Way Back to a Miraculous Recovery
Finally tonight here, the fire captain we already named our person of the week. But nearly four months later, we go back. Captain Pete Dern, climbing up the ladder, about to vent the roof when it gives way. Flam flames erupting, people yelling. Get him out! Reporter: Raced to the hospital, in critical condition, and prayers ever since. A leader and a good man. Motivated. Reporter: That motivation, from a determined father and husband. And look at him, 105 days later. Captain Dern, walking again. One step at a time, his wife on the left, daughter on the right. Close your eyes. Reporter: Every step celebrated. The family thanking the firefighters, they've done shifts to make sure there was always someone there with him. Thank you guys. You're welcome. Reporter: And today, captain Dern walking out to applause. I need to thank my wife and family. They've been here with me since the beginning. We've had firefighters around me since the beginning. And it's just very comforting to know that someone is there all the time. Even at night. Reporter: And every night, until he leaves, walking up the stairs. Climbing his way back. And the family told us they hope he will leave the hospital in three weeks. We're pulling for him. I'll see you back here on Monday.
