cause and we absolutely believe that the number of fire fatalities will increase. reporter: 70%, when you get to 100%, will you then conclusively say there are no victims in there or will it take more after that to go through the remains of this building to say for sure? if you get to a hundred today or tomorrow, will the search be over at that point? can you speak up a little bit louder? when you get to 100%, the search, once it s done at that point, will the search for remains be done at that point or will they have to sift through the remains of the building? will it be completely done at 100%? once the search is completed, the primary focus has been on the location and recovery. that s what we ve been talking about for the last three days. we re going actually on day four. this started last friday, december 2nd. so we really on our fourth day.
