agent brad garrett. you have experience in counterterrorism. what is the main concern right now overseas or is this more of a knee-jerk reaction? >> they are concerned about other attacks. was this particular bomber connected to other bombers? they may link him to others via the bomb itself, how it was built. what was it made of. and all of his social contacts. i suspect a number of the raids have to do with people he has been communicating with in recent days. >> the scary part of this. paint a picture of the terrain. radicalized people in manchester, whether they are homegrown or whether they did time in one of the camps. that is the reality. there are thousands too. many for the law enforcement to pick up without probable cause. what are they to do? brad: this goes to how good is your informant network within the various communities in and around manchester? as we both know that is touch and go. sometimes it's good. sometimes it's not. as a result, you end up to a certain extent being at the mercy of a particular event happening and somebody

former fbi agent brad garrett says we give terrorists too much credit because it does not take much skill to carry out an attack, the entrance of the manchester arena, which would have been much easier than inside the secure area. >> i think extremist groups have figured out they get as much bang for their buck doing these low-tech, unsecure attacks, where it makes it almost impossible for us to defend against. tim: the department of homeland security released a statement, saying, "there are no credible threats to venues in the united states." tim barber, abc 7 news. jonathan: tim, thanks. governor larry hogan tonight calling this an unspeakable tragedy, saying that he is praying for the victims and their families. stay with abc seven for breaking news coverage and sign up for text alerts at wjla.com/text. --helle: new at 11:00 >> i love you, man. i will emotions come a large gathering to honor a college student killed in a possible hate crime. richard collins recently became a lieutenant in the army, his future cut short when he was stabbed to death. jonathan: tom roussey has the emotion

we got perspective from brad garrett who served as f.b.i. agent for 22 years and he believes that people inside the f.b.i. are not pleased that comey was fired abruptly and not in person. he thinks that the firing could hurt morale. the overall impact could be limited. >> this is a small there are 11,000 to 12,000 f.b.i. agents. i think it's of what is getting done. >> the reaction around town. i can tell you here outside the f.b.i. headquarters people are asking what will happen next. we are looking for the person who finds himself at the center of this. used to be a well-known local person. >> so whether he did it for good or bad reasons, it i don't know the exact, his exact listening for it except that he felt it needed to be done. he is our president. i will stand behind what he does. >> the d.c. visitor and the trump supporter speaking as he watched activists protest the termination outside the white house. >> we need a special prosecutor who can get to the bottom of who did what? who knew what and when. >> thrust in the divide, new dep

we have joined by brad garrett. it's good to get your appointments on these things. your impression of mueller's appointment? >> i can't think of anybody better to pick than bob mueller. think of his experience. 13 years as the f.b.i. director. long-term federal prosecutor, u.s. attorney in two districts. he knows the f.b.i. he knows the prosecution and the judicial system. he knows politics. but he is a straight shooter. it's a unique combination in somebody. great pick in my view. jonathan: i have heard a lot of people talk about a special prosecutor. be careful what you wish for. the net that will go out on the case will be big. i could include everybody. democrat, republican, it doesn't matter. anyone with contact with the russians will find out what the contact was and what it entails. what do you think will map with the investigation? what is your best guess? >> my best guest is mueller will get to the bottom of whatever this is. now, inea anything? that is the other possibility. conversations they would like to figure out if they were truthful or accurate or n

agent brad garrett for how this week shaked up the agency this week. it's good to get your perspective. there saying wait a second, is it a big deal to fire the director of the f.b.i.? it's well within his power to do so. brad: yes. you have to look at the reason why he fired him. they used the cover of hillary clinton's emails. nobody actually ever brought that. the optics of it is really poor. it's apparent to most of us, current and retired agents, that this has everything to do with the russian investigation. >> but just because you fire the head of that agency does not mean that investigation stops. there are a lot of agents below him. a lot of people look at him as a political figure anyway. there are a lot of agents underneath that are carrying out this investigation. it doesn't change the trajectory of this investigation, does it? brad: not at all. you are talking about 12,000-plus f.b.i. agents, 36,000 f.b.i. employees. divide it up into various divisions, you have an x number working on the russian situation. they're continuing to work. my gu

. >> reporter: fbi special agent brad garrett, now an abc news consultant, worked the levy case for years. >> her driver's license, her credit cards -- >> reporter: her cell phone? >> and her cell phone were still in the apartment. that's baffling to me and others because the whole idea is when you're going to leave, you're at least going to take an i.d. there were only two things missing, her keys and a ring. >> reporter: a gold ring with her initials, "c.l." in diamonds, a college graduation gift from her parents. what are you hearing from the police? >> they were sort of nonchalant, because what >> reporter: police do canvas the area, including nearby rock creek park. and susan levy begins her own search, looking through her daughter's cell phone bill. >> i saw this number that was being called many, many, many times, and i decided to call that number, and it turned out to be gary condit, and he answered the phone. >> reporter: what did you say? >> i was kind of surprised, and i said, "do you know where my daughter is?" i thought to myself, this is wrong. >> come on in, make yourself c

former fbi agent brad garrett is an abc news consultant. >> the idea that he would bring elizabeth torise me one bit because he needs a cover story. look at this, i'm bringing you to church with my family. isn't this a wonderful thing? >> reporter: despite outward appearances, authorities say cummins' intentions become less of the spirit and more of the flesh. d.a. brent cooper says investigators discovered a special system cummins devised to exchange secret messages with elizabeth using the same e-mail account. what was kind of the nature of those messages? >> things that only people that were in an intimate relationship would share. there was a message that says, "i saw you standing by your backpack and just wanted to tell you, you have a really nice blank." . >> reporter: it appears the two were much less inhibited on instagram. cummins posts, "you're all my heart ever talks about. it was love at first sight, at last sight." and elizabeth, "i look forward to going to school just to see you. i love you." and she told her friend erin she had big news about a relationship. >> she said

. >>> former fbi special agent and abc news consultant brad garrett joins us now, of course, the key why? tell us what investigators are doing right now? >> well, the key, robin, in this case in my view is because they were residents. this isn't like tourists there for, like, a week or two. they have links into the community. so, i'm going to guess this has some tie to their relationship with people who live in belize. look at this. you have a vehicle found in a sugar cane field, the bodies ten miles away. there's apparently duct tape involved. they were strangled apparently. this sort of goes beyond just the run-of-the-mill robbery. there is some connection between these two and the community in belize. >> you take that because of you saying because of the duct taping and the strangling, you think that suggests something to you as you were saying? >> it certainly does. i mean if you're going to rob them why do you go to all that trouble? i mean, driving ten miles, et cetera, keep in mind, robin, that belize is a transshipment area for drugs. i'm not suggesting it has anything to do
