But his mother is telling reporters there were no red flags that she saw.

Elizabeth, this community has been just really shattered with this thing.

And it's just so heartbreaking, like you said, to see that little guy just having to talk about that.

But going back to what the mother said, like she may have not seen like anything that she would notice to be out of the ordinary.

But I think when we look at these types of school shootings, these little behavior patterns that people are looking for, when you have a team of investigators piecing together somebody's life in one thing, you put all these things together and it looks like oh yeah, maybe there was something there.

We don't know that in this case just yet.

That's what police are looking for.

It's an extraordinary sequence of events.

When you hear that timeline, what do those details reveal to you about possible premeditation?

Well, that's the question that the Bend Police, the Deschutes County Sheriff's Office are gonna answer.

It certainly seems like they had a plan, and they were determined to get through there by going in, shooting the glass out allegedly, and then making entry.

And then fortunately, that, uh, concealed carry person was there to eliminate the threat.

And, you know, Boris, no matter what we say here tonight, nothing's gonna ease the pain of these families that have lost their loved ones and their teachers.

But having said all that, these teachers, these drills I think that we go through as students these days, here in Bend tonight probably saved a few more lives because they were locked down.

They made it harder for the shooter to get th- before that concealed carry permit could, uh, person could come and eliminate that threat.

I, I wonder if you think that that person is someone that officials are, are zeroing in on tonight and, and getting their view of what happened.

I mean, short of 9-11, where the whole country shut down for a few days, this was an entire city that shut down for four or five days while they were looking for the suspects.

Is that correct? Yeah, it was kind of surreal to see a shelter in place for an entire city.

major U.S. city like Boston and the suburbs around there, Watertown, all those places that we wound up.

So, yeah, that was unheard of.

It was a tough decision to make, I'm sure, but it was the right one at the time, not knowing the other dangers that were out there and considering what had happened the night before with the attempted carjacking incident.

of the person and them trying to head to New York.

So yeah, like, uh, it's kind of like a scene out of a movie, you know, for a boy from Tennessee to be, uh, thrown up into Boston where they may not understand what I'm saying, but, uh, I'm just kidding.

What makes a reporter trustworthy from law enforcement perspective?

Can you take us back 25 years ago and talk about what it was like receiving that call from FEMA and being dispatched to New York City?

Absolutely.

So I was, uh, working with FEMA at the time.

I had grown up in the fire and EMS service, uh, prior to that since I was 16, so I had a background in fire and EMS.

But at this time, uh, FEMA, uh, was in Greenville, Tennessee, which is just a couple of, uh, exits down from my hometown.

So I was there helping with some flooding.

And we had, uh, converted an old grocery store into our, uh, joint operation center there.

25 years later, what do you think America needs to remember about that day?

Our sources are stressing this person has not been charged tonight, but I wonder what stands out to you as we're learning this new information.

Well, Caitlin, what stands out is just the remarkable work earlier of the Operational Technology Division engineers and scientists in there putting this stuff from the slack together to be able to get and release this photograph tonight to lead to where we are now.

So just in a matter of hours, similar to when we flipped the posters over at the Boston Marathon bombing on stage there, we flipped those posters around.

Within a couple of hours, they started to feel the pressure.

They unfortunately murdered an MIT officer and then tried to kidnap a person before they wound up in Watertown.

Similarly, it seems like some people are feeling that pressure tonight.

At least there's a lead where this person that may have been detained, maybe we all hope it's the person, but even if it's not, it's somebody that may know him.
