as they're clearly searching for someone. gustavo, i want to make sure we're really clear, we have heard previously from the president of mexico that there were some 30 people that were still missing tuesday night. are there still some 30 people that are still missing at the school today? >> officially, we haven't heard any number. overnight, they had set up a signup sheet for those that have somebody missing, so they could write the name and then for people to come back and write the names of people who have been found. however, we're hearing from security people there that a lot of people just came and signed up names and they're not sure if they're real or not. so we haven't heard officially from somebody here on the ground as to the actual number people that might have been looking for or how many might be missing
