update from law enforcement for another couple of hours, because it is so early in this investigation. one of the things, john, that we re seeing that there are names circumstance light trying to figure out who the person is. that will be a big help, to finding who they are. but those accounts who you re hearing inside this subway, i want to paint a picture for viewers really quickly, if i could, john, is that this has happened during the rush hour, at a time when, on a subway line that is a commuter train. people were just probably going to work this morning. this isn t sort of a tourist area of brooklyn, where it would be incredibly packed, but even still, just horrific, horrific on this train. and actually, we re getting moved right now. i ll go back to you john, if i can. brynn gingras, having a little bit of problem with your audio right there. joining me now is the new york congressman, lydia velasquez. i just want to confirm, can you hear me? yes, i can hear you.
