Let`s go to CW Jensen, retired police captain. How do you piece this together?
CW JENSEN, RETIRED POLICE CAPTAIN: Well, I want to let everybody know -- because people ask me all the time, what`s the difference between a suspect and a person of interest? And I say, nothing. They`re the same. They have information that points this suspect, this person of interest to these murders. Obviously they know he was there on the street. They`ve got some evidence. They`re throwing it out that he`s a person of interest but, believe me, there`s no other person of interest in this case but this bad guy.
COSBY: Let`s go to Dr. Michael Arnall. How do you piece it together? You`re a forensic pathologist. What kind of forensics could put this together and how did they tie this guy pretty quickly to the scene?
DOCTOR MICHAEL ARNALL, M.D., BOARD CERTIFIED FORENSIC PATHOLOGIST (via telephone): it could be a couple of ways. They may have found shell casings or something of that nature at the scene where they found the bodies, that are similar to the shell casings in this gentleman`s previous case, or people are creatures of habit. They may well have this babysitter and the kids going into some type of business as a habit, and they may have gotten some video indicating that someone was following this babysitter and the two kids out of the business or got into a car in the parking lot. So, there may be some video we don`t know about that police are using to develop this person of interest.
COSBY: And, Pat Brown, criminal profiler, author of "only the truth," what leads would you follow now?
Now, we have a triple homicide, two beautiful kids, a wonderful neighborhood guy who was trying to help out a family. How would you sort of follow the leads and get this person of interest?
PAT BROWN, CRIMINAL PROFILER, AUTHOR, ONLY THE TRUTH: Well, Rita, I think the police are being tightlipped for a number of reasons. There`s one bad guy. And the question is, yes, was this a carjacking? He saw them some place and try to steal the car and end up seeing everybody?
COSBY: By the way, Pat, you`re great at this stuff. What do you think? That was my sort of first reaction, it`s a Mercedes, that`s one, an elderly guy, too.
BROWN: But here is the problem, I think, the police are also looking at and they have to clear with the mother. They have to clear her. When she gave her interview, she said some things that were a little concerning. She said that the babysitter was a nice man. That`s before he was found out to be dead. Why didn`t she say he is a nice man. The first word out of her mouth was she wants to know what happened to her children, not that she wanted them back. Like she knew something had happened to them.
It was very peculiar. Her demeanor was odd. But as we all said, sometimes you said, people are shock. They have weird ways of behaving. But they have to clear her and find out if she has any connections to this man they are looking at as a suspect. So, they have to look at all the possibilities to figure this out.
COSBY: You know that -- some interesting points, Pat that you bring up. CW Jensen, retired police captain, I thought Pat just said some interesting phrasing. No indication that she is a suspect whatsoever but the verbiage is kind of interesting, but sometimes that just happens in the heat of the moment, don`t you think?
JENSEN: When I`ve interviewed people, they do, they say goofy things. They`re upset. But I mean, I think what she is saying is absolutely right. You can`t look at a case singularly. You`ve got to bifurcate it or look at different things.
So, was the mother involved? Was the mother`s sister involved? Was the suspect, you know, involved with the mother -- I mean, these things can just get so confusing. The bottom line is, right now, the police are comfortable enough to say that they have a suspect, a person of interest in this case, and if you know where this cat is, call the cops.
COSBY: And, you know, Pat Brown, they zoomed in on this guy pretty quickly, so there`s got to be some pieces there at the scene tying this guy. What do you think is connecting him so quickly?
BROWN: I`m not sure. Maybe they have some information through somebody else, considering where he lives, so near to the family. Obviously he`s a really bad guy, too. They know he`s there and looking at his pattern. This guy is dangerous as heck. And, where is he now? Maybe he`s just nowhere to be found right now.
I can`t really believe - you know, the carjacking thing is kind a weird to me because, yes, it`s a nice car but it`s 20-years-old. Is that really what you need to be stealing? On the other hand, he seems to be a piece of crap, so, who knows what was going through his head it at the time.
COSBY: Yes. Who knows what`s worth it to somebody. It sounds like a horrible individual.
Real quickly, Alexis Weed, he has a rap sheet a mile long it looks like.
WEED: It is a mile long, Rita. And it`s hard to know where to start. But this Lee, he was recently released from jail after standing trial and being acquitted of murder of two individuals and also involved in injury to another individual in a shooting in a 2008 shooting incident.
Also, he was charged with -- in 2012, January, charged with resisting arrest. Altercation of a firearm, obstruction of justice. Carrying a pistol without a license, Rita.
Also, February of this year, third-degree robbery charge. He was released, Rita, just in February on a $10,000 bond.
