NOW with Alex Wagner | December 14, 2012
>> justice correspondent pete wmsz joins us now. what is the latest information that you have?
>> well, i think we have to be very cautious here and say this number is undoubtedly going to change as we go through the next few hours here as the authorities in connecticut finish going through the school, but this is appearing -- this looks like it's going to be the worst school shooting in recent u.s. history . we have been told that the number of shooting victims is around 20. that's children and adults. there are indication that is it's going to be higher than that. we just don't have a firm number at this point, but i think the point is that there are a number of children that were shot, a number that were apparently killed. this will be the worst school shooting here perhaps in u.s. history .
