>>> two years ago today, disaster struck haiti in the form of a massive earthquake. we were there by the next morning. witnessed the destruction, got to see the outpouring of aid that followed, but the suffering continues, of course. as of today, two years later, just half of the mountain of rubble caused by the quake has been removed. rebuilding has been painfully slow. more than 600 schools have been rebuilt or reteared. 100,000 temporary shelters replaced homes wiped out. amid the misery, stories of kindness and love, we learned about one after we arrived to cover the quake two years ago. a man chased me down to tell me about children in an orphan age he was concerned about. ron allen met an american man frantically searching for two little girls he was in the process of adopting from haiti . tonight, ron revisits that story and that family.

>> reporter: we actually know them pretty well. we met tia and naita now 8 after the earthquake. the wilsons were in the process of adopting them.
>> the center is where exactly the girls were. i remember that helpless feeling of we're never going to see them again.
>> let's go get this done.
>> reporter: mike flew to haiti and found the girls safe. about a week later, the u.s. finally began giving american families adopting children permission to bring them home. for the wilsons , that meant tia could leave immediately, but naika's case was further down the list. it took weeks to get her home and months before she truly believed she was a member of the family.
