I think they were known to be alive, 'cause on the fire's report was said that they found 8 people dead and we know that Derek and Laura were not at home when it happened, it means they were at school, at least Derek, since we know he wasn't  home schooled (3x08), so people knew the Hales (4x06), even if they tried to protect the city staying in the shadows, they had a public life as everyone, otherwise that would make them suspicious. The problem might rise if the bodies were so burned to not be recognized and Derek and Laura fled right after the fire, so there was no one to recognize them; plus on the newspaper in S1 finale, there's an article about still a Frederick S. Hale nowhere to be found....wait, this might fight my theory, since now I think he's DEREK xD

Plus I know there are writers who never get their name on the credits, but still they won't if they'll add newbies who will (maybe) have their name on the credits. My point was: last time they changed something in the writers room (S2-->S3), it hadn't a good resonance on the plot (IMO).
