but we had 53 that were accounted for in the middle of the day and we're up to 102, so we're making great progress with the assistance of families, loved ones. they're calling our hotline. we have a family reunification center. everybody is cooperating. >> just so that people understand the numbers, you had 53. that number of people you could account for went up, but the unaccounted did not go down? >> correct. i don't know which -- how many went from one list to the other, but yes, we still have 99 and the 99 could go up because many of those people might have been visiting, they might not have been registered, so we don't really have all the information about who might have been in the building. >> now, what have you been told from the search and rescue people about why they're focusing on that one area in particular in the parking garage.
