Cornell faculty debate no-confidence vote for administration | Elizabeth Vargas Reports Full Show

Elizabeth VargasHOST
Does this look to you like a pattern or an incredible, horrible coincidence?
M
24:05Mary Ellen O'TooleGUEST
And the pattern right now is based on primarily on the behavior, but also cause and manner of death.
M
24:12Mary Ellen O'TooleGUEST
So what they have to do in addition to that is they have to look at forensic science findings because those are the most secure ways, certain ways to link cases together.
M
24:23Mary Ellen O'TooleGUEST
So, for example, I've seen in the serial murder cases that I've worked as a FBI agent profiler, A serial killer will often, they make mistakes and they leave behind their own evidence.

I work specifically on profiling serial murder cases and assisting law enforcement all over the world in how to understand these offenders and how to make sense out of their crimes.
M
2:14Mary Ellen O'TooleGUEST
I think Joseph Paul Franklin will be very interesting to talk to because if you scrape away the racism, he is still a cold-blooded, predatory individual who was driving around the country shooting and killing people.
M
2:29Mary Ellen O'TooleGUEST
And so to say that that's the reason that he killed is very difficult for me to accept.

Megyn KellyHOST
You don't know what you are starting inside of yourself or someone else or your spouse.
M
119:45Mary Ellen O'TooleGUEST
Yeah, certainly can be, um, it certainly can be dangerous, and I'm, uh, m- my sense at this point is that Chris is not happy with his life, and he's not really blaming himself.
M
119:58Mary Ellen O'TooleGUEST
He may be feeling very trapped, very backed up in, in the corner, may feel like he has no control.
M
120:11Mary Ellen O'TooleGUEST
So he's now engaged in this behavior where it, it's almost escalating to the point where he's rubbing it in her face.

A former FBI profiler on the Nancy Guthrie case
M
7:41Mary Ellen O'TooleGUEST
And a robbery gone wrong would suggest something that I have never seen in my career.
M
7:47Mary Ellen O'TooleGUEST
Not that that makes it impossible, but a robbery or a burglary is described as taking property that belongs to another person.
M
7:56Mary Ellen O'TooleGUEST
And most burglaries, at least those here in the United States, occur at a time when the burglar doesn't think somebody will be at home because what their intent is is to go in, take things of value, and then to leave.
M
8:11Mary Ellen O'TooleGUEST
But if you go into somebody's home at one or two o'clock in the morning, you're pretty guaranteed you're going to run into somebody.
5 MINS LATER
S
13:44Samantha HawleyHOST
From all you've learned as a former FBI profiler, what attributes would you be expecting in a perpetrator in a case like this?
TMZ: New Ransom Note Demands Crypto, Describes Consequences
23:04

Laura CoatesHOST
Mary Ellen, based on what you know so far, do you think there's enough there for someone in the public to, to try to help solve this, or is more needed to try to spark that key tip?
M
23:18Mary Ellen O'TooleGUEST
Well, I absolutely think there's enough out there right now for someone to call in, to spark somebody's, um, i- interest and to say, "I'm not totally sure, but, um, there's just something about that, um, outfit.
M
23:37Mary Ellen O'TooleGUEST
Um, I heard somebody say comments about kidnapping this woman a week before." There's definitely enough information out there for somebody to call in.
Laura CoatesHOST
Mary Ellen, if this was indeed a kidnapping, and if the person who did it has not been communicating with the family or the FBI, I mean, what would that tell you about the profile and, and psychology of a criminal who would do something like this and then stay in the shadows, stay quiet?
M
25:44Mary Ellen O'TooleGUEST
I think there are several possible reasons for that, and, uh, one of them is he's dead.
M
25:51Mary Ellen O'TooleGUEST
Um, another possible reason is that he did not anticipate the reaction of, of the general public and of law enforcement, and that's not something that you can plan for.
M
26:03Mary Ellen O'TooleGUEST
If you've never done this before, you are, uh, probably really taken back by how much attention, and rightfully so, that this case has gotten.
Remembering Civil Rights Leader Rev. Jesse Jackson
47:29
49:53
Jake TapperHOST
Uh, how long could it take for a national retailer to, to find that information, and is that something that a perpetrator would be thinking about? Maybe disguise their, their tracks while they do that?
M
47:40Mary Ellen O'TooleGUEST
Um, it will take, it could take a while, uh, but I'm confident that they are giving it priority because this case has gotten so much attention, and they should give it a, um, a priority.
M
47:51Mary Ellen O'TooleGUEST
Um, I, it, it depends on whether or not the offender thought ahead that far to think, "What if they track my clothes back to Walmart and then they go, can go back and see the day that I bought it and then get the cameras?" Some people do think like that, and this is an offender that may have not been perfect at everything, but there certainly was evidence of, of pre-planning.
M
48:14Mary Ellen O'TooleGUEST
So they may have thought enough ahead to not buy everything on the same day or not use the same Walmart, and that will make it a lot more challenging for investigators to go back and attempt to track it.
Jake TapperHOST
Why do you think so many, um, s- influencers, YouTubers, et cetera, people who don't necessarily have investigative experience, rushed to accuse members of the family?
M
50:08Mary Ellen O'TooleGUEST
I think one of the reasons that, that people do this, quite frankly, is, is when you see a case like this on, on television, oftentimes, it, it, it's portrayed as being a family member.
M
50:20Mary Ellen O'TooleGUEST
And I think if you don't have that kind of investigative background where you know that every time a case like this happens, whether it's a child, um, kidnapping or an adult, you eliminate the family first and foremost as, as people that have been around that person, uh, and then you move on.

Megyn KellyHOST
I don't- Is- Are these two things consistent in your mind? And have you been thinking at all about a profile for this guy, who, who took her?
M
31:51Mary Ellen O'TooleGUEST
The fact that he walked up there, and what was really striking to me, um, because it's hard to know, is this a really good writer? Is this someone who's really articulate when he puts pen to paper? But th- the comfort level that he seemed to show, at least in my opinion, um, he was very casual.
M
32:17Mary Ellen O'TooleGUEST
That knowing that within moments, he was going to get into the home and commit one of the most violent crimes we know of, which is kidnapping.
9 MINS LATER
Megyn KellyHOST
But what you say, who, who kidnaps an 84-year-old woman in the dead of night, and now you actually have the blessing of a picture of him doing part of the crime, what does that profile look like?
Investigators Examine New Message In Guthrie Case
10:59
Anderson CooperHOST
Mary Ellen, I mean, i- given the length of time, given, you know, the demand of money, the, the reach out to both local and TMZ, do you have a sense, uh, or, uh, do you have any kind of working hypothesis of a profile of this person?
M
11:16Mary Ellen O'TooleGUEST
Well, a little bit more than I, I did earlier today, but the one thing that's, that is really striking to me, um, and John and Jonathan, I think, um, hit on it as well, is: What's the purpose of today's communication? What was the reason for it? Because the reporter said there was no mention in that in terms of the note today, um, of deadlines or, um, information about, um, how to make this ransom, um, effected, um, messages to the family.
M
11:47Mary Ellen O'TooleGUEST
If that's true, what the heck was the purpose of this, of this letter? Was it to provide, um, leads for the police department? Was it to hurt the family? Um, was it to taunt the police? So if this is an imposter who wrote both notes but did not kidnap, um, um, Nancy, then why is he...
M
12:08Mary Ellen O'TooleGUEST
He's almost guaranteeing himself, um, years in, in federal prison for what he's doing without any f- financial benefit.
M
12:21Mary Ellen O'TooleGUEST
Um, and why the third-party intermediary? Why send these, the notes to the media? Because they immediately turn it over to law enforcement anyway.
M
12:30Mary Ellen O'TooleGUEST
So there is a focus on, on the media here.... which may give us some background about what this person is obsessed with.
FBI: Ransom Note Linked To Guthrie Disappearance Includes Two Deadlines
17:10
Anderson CooperHOST
Does that suggest anything about whoever took her? And also, Harvey Levin saying it seemed like a rational actor, at least through the words used in a note.
M
17:20Mary Ellen O'TooleGUEST
Yeah, it certainly does to me, and I'll tell you, um, briefly what, what it means.
M
17:24Mary Ellen O'TooleGUEST
It, it, um, reinforces for me the suggestion that this was a well-planned-out attack.
M
17:32Mary Ellen O'TooleGUEST
And when you have a, a low-risk victim, uh, that is victimized in a low-risk environment, their own home, in a nice neighborhood with, with very little crime that's occurring in the neighborhood, and then you have an offender who's able to access that victim in the middle of the night, and possibly, uh, without breaking down a door or breaking a window, that tells me that, um, there's a good possibility the victim was specifically targeted.
M
18:00Mary Ellen O'TooleGUEST
But number two, it also suggests that the, that the planning had to, um, include some kind of recon before this crime occurred.
M
18:09Mary Ellen O'TooleGUEST
And that recon could be, um, going through the neighborhood and seeing what the dynamics of that neighborhood were at 1:00 in the morning.
M
18:17Mary Ellen O'TooleGUEST
It could also have included going into that home without her knowing about it ahead of time.
Unexpected Inflation Drop

M
16:06Mary Ellen O'TooleGUEST
Well, they really want to get the public to go back on the day of the shooting and think about where they were in regards to that map and the locations on that map.
M
16:18Mary Ellen O'TooleGUEST
A lot of people will listen to the news reports and dismiss them, and that's just common.
M
16:24Mary Ellen O'TooleGUEST
So they want to get people to think about, could you possibly have crossed paths and not thought about it? And that's important because...
M
16:35Mary Ellen O'TooleGUEST
But back on Saturday, if you were driving around, you probably looked at this individual and were thinking about your Christmas list.
Pamela BrownHOST
How often is it that a suspect would change maybe the way they walk or do things, knowing that law enforcement would rely on video footage like this to try to track them down?

Anne-Marie GreenHOST
According to O'Toole, serial offenders can sometimes channel their compulsion to kill into other crimes, like stalking or voyeurism.
Kirk's Alleged Killer Makes First Virtual Court Appearance
8:57
Anderson CooperHOST
I mean, obviously he just said his name I- in the he- the hearing, um, but in that text exchange with his, his partner's roommate, uh, what stood out to you?
M
9:11Mary Ellen O'TooleGUEST
Well, look, listening to his texts and reading them, I kept going back to the phrase that you just referenced, which was, "Hate cannot be negotiated out." It's a weird statement to make, and as I, as I read it and I went back over statements that I've reviewed over the years when I was still with the FBI, it's, it's...
M
9:31Mary Ellen O'TooleGUEST
The way it's stated almost seems like he's saying, "And I had no choice," because it could not be negotiated out.
M
9:40Mary Ellen O'TooleGUEST
So, um, I'm sure investigators are going to be looking at that and what does that say? That...
M
9:48Mary Ellen O'TooleGUEST
It's, it certainly suggests to me that he was feeling somewhat desperate to a- address the situation in an extremely inappropriate and lethal way, and I think that's consistent with his personality which is...
M
10:11Mary Ellen O'TooleGUEST
He doesn't reference the victim, he doesn't talk about Charlie, he talks about his mom, he talks about his "old man" and how the father is gonna be upset with him.
