agent ahern, it's great to have you with us. first i want to talk about santiago's first court date monday. that's when we're expected to see him face those charges. but the fbi is currently searching his house, probably speaking to his family both in new jersey, as well as alaska and possibly here in florida. what are they looking at as they try to put together a theory for motivation behind this? >> i think the critical part is they start with what's known as a timeline. they will pretty much trace all of his travel, all of his contacts, where he's lived in the past, look at his military and employment record. and no stone will be left unturned in something like this. i think also too that anything on the computers, on the phones, the social media profile will be critical in trying to put together and piece this timeline together to find out what the real motive was and why he did what he did. >> agent ahern, i've been talking to a lot of people earlier and throughout the course of the day about some possibly missed signals. w
