mass shooting. additionally there's new word how his father apparently helped him obtain a gun license he likely should not have had given the red flags in his recent past. this young man who apparently had attempted suicide and yet his father helped him get a gun license. more on all of it shortly. first, though, because we now have the names of all seven people killed. we want to begin with who they were. he'd just celebrated his 50th wedding anniversary. his wife and four daughters were everything to him. his daughter telling cnn he would have turned 70 on friday. despite being the oldest victim at 88, steven strausss was still active, still enjoying life according to one grandson. nicholas toledo had eight children, countless grandchildren. one of them describes him as a loving man who was creative,

adventurous and funny. in highland park from mexico visiting family he was 78. taught preschool, served on the staff of a local citadel, just couldn't find a lovelier person. katherine goldstein was 63, fatally shot fleeing with her family. and finally there are the mccarthy, ages 35 and 37. they were at the parade with their 2-year-old son adan, and they died trying to protect him. tonight he's safe and surrounded by people who love him, who will do all they can for him but who cannot take the place of his mother and father, in his life, his memories or his heart. a gofundme page has already raised $2.6 million on his

behalf for his future. in a moment we'll be joined by a husband and wife who cared for adan after the shooting. first, though, more from ed lavandera in highland park on the shooting. >> reporter: earlier today the shooter appeared in court. he was denied bond by the judge. he appeared via zoom, but we've also tonight obtained an image of that second assault-style rifle we were told by authorities was inside the vehicle when the shooter was taken into custody monday afternoon. the image of that quite chilling especially in light of what authorities are telling us tonight, anderson. they have now reason to believe after the shooting here in highland park the shooter drove 2 1/2 hours towards madison, wisconsin, where he had thoughts of carrying out a second attack. investigators talked earlier today about what led them to that conclusion. >> certainly our investigation

has gone very much into what happened after the shooting, what the plan was. investigators did develop some information that it appears when he drove to madison he was driving around. however, he did see a celebration that was occurring in madison. he seriously contemplated using the firearm he had in his vehicle to commit another shooting. >> reporter: anderson, investigators went onto say that they believe that the gunman didn't have enough information, hadn't researched the situation there enough to carry out the attack, and turned around and drove back to illinois where he was taken into custody. investigators also say here at the crime scene in highland park they found three 30-round magazines and 83 shell casings in the area here where the deadly attack took place, anderson. >> there have been a lot of questions how he was able to get a weapon. talk about this reporting that his father despite reports of a

prior suicide attempt or talking about suicide i think it was in 2019. did his father sign an affidavit which helped his son get weapons? >> reporter: so here in illinois anyone to obtain a firearm has to apply for this card that allows them to do so. but we have also learned that before all of that in 2019 -- in april of 2019 family members had reported to highland park police an attempted suicide by the gunman. and then five months later there was another call from family members saying the gunman had a collection of knives and he is threatening to, quote, kill everyone. despite all of that we have learned also that the father sponsored the gunman's application to obtain firearms here in illinois. and we know from authorities that this gunman had gone onto legally obtain two assault-style rifles as well as a number of firearms. >> i also read in reporting and

correct me if i'm wrong, when police went to respond to the second report where he'd threadened to kill everyone in his family, that his mother denied that threat took place as did the shooter. and that the father claimed the knives belonged to him, the father. is that correct? >> reporter: right. the knives were returned to the house there because the father claimed they were his, and no one in the family filed a formal complaint that would have taken it to the next level. >> they were at the parade with their kids when the gunfire erupted and came across a toddler adan mccarthy and cared for him until he could be reunited with his grandparents. i'm so glad you and your family are safe. can you just walk us through what happened after you heard

shots and did you realize what was happening right away? >> we happened to -- well, initially we thought we had snagged luckily really the greatest seats i maybe ever had in a parade ever before, really close, unfortunately to what ended up being the epicenter of what happened. i saw from where i was standing that there was a physical i thought initially maybe fireworks had gone off too close to the crowd or something. but then the sound didn't stop. it didn't take much time before we realized we needed to run for cover. the whole crowd around us started stampeding and we just ran as well. >> and greg, when did you -- what happened then when you started running? >> we were there with our neighbor, we heard, pop, pop, pop, pop like dana said. we started running.

my neighbor grabbed our son, i grabbed milly our 4-year-old, and dana grabbed our 8-year-old and we ran behind the walker brother's pancake house underneath. there's a garage underneath it and that's where our car was parked. and we ran underneath to get to our car. >> we first actually ran with the crowd and initially took cover behind a brick pillar behind dairy queen in a heap, like a pile of so many people all together waiting for some stop in the sound. and when we finally did hear a pause that's when we realized immediately we had to get as far away from the direction where it was coming from as possible, which is how we made our way to that back staircase. >> and dana, how did you end up finding adan? >> so once we got underground we put all three of our kids into our cars parked right next to where the staircase undecomes o

underground -- >> sorry. we're getting a problem with signal and try to correct that. let's take a short break. we'll be right back with more. .s a little easier.

she was shaking physically. i was concerned she might drop the boy so we walked over to see if she needed help and ended up taking the boy. but he needed a minute -- >> she handed the boy over to us. we could tell it wasn't her blood, wasn't his blood. she was shaking. she was having a hard time talking. and we looked at each other, she handed him over to me. she then sat down and dana attended to her. >> and i understand you first stopped to the fire department with adan. what did they tell you? >> so then we jumped in the car with our kids and adan, and we decided to go to dana's parents house, and on the way there we passed by the highland park fire station, and we pulled in and the police looked like they were getting ready for war and machine guns and helmets and i stepped outside with adan, and i said he's not our boy, what should we do, and somebody said

i'll never forget we can't be baby-sitters -- he wasn't disrespectful but said we can't be baby-sitters and can we take care of him, and we drove to dana's parents house and that's where we kept him for a couple hours. >> and was he saying anything to you? >> he -- i just trying to get his name because i wanted to be able to talk to him in a calming way. i was guessing he was somewhere between 2, 1/2, 3, and every time i asked his name his response was mom and dad will come and get me soon, they'll come and get me soon. and i was like, yeah, buddy they'll come and get you soon. we kept trying to get his name out of him so often because we wanted to be able to talk to him. and he just seemingly was okay. he wasn't crying -- >> he was walking cartoons with

our 4-year-olds. >> my dad took him to the back and totally otherwise normal. i mean if you didn't know where we'd come from you wouldn't guess there was anything wrong with him. he was markedly calm. >> and how were you finally able to get him reunited with his grandparents? >> well, we went to the fire station. i gave the police officer my in-law's address and my cellphone number. and then we got a text message from a detective, and the detective came over and couple hours later took adan. we put our car seat and put it in the squad car and took adan to where families were being reunited. >> how are you all doing? how are your kids doing? >> our kids are upstairs. >> with our parents. >> eating macaroni and cheese

and watching cartoons. so they're doing okay. >> it started to come out when i think they're thinking about it and i don't realize they have it on their mind. my 4-year-old has particularly started more frequently ask me why did we make them go to the parade, she didn't even want to go, which actually was true. they've got a lot of questions. we just keep trying to remind them how very incredibly lucky we were. yes, it was a crazy scary thing, but we were so, so lucky in the end to have all made it through it okay. and we just had to keep focusing on that part of it. >> yeah. i'm so glad you're okay, your whole family and for helping adan.

we should all be lucky in that station that people -- that a child finds people like you. thank you so much. >> anderson? anderson? >> yes. >> can i say something or i'll never forgive myself? >> sure, sure. >> we need to stop giving ar-15 guns to people with mental health issues. i'm not trying to say anything political right now. i'm speaking as a father. i'm speaking as a husband. i'm speaking for this community. i'm speaking for communities in texas, in florida, for synagogues, for churches. there are damaged people walking around our society who need help. i feel empathy for them. we need to find a way to help them. i know that they shouldn't have access to ar-15 machine guns. i understand that this bill that was just passed politicians on both aisles are going to say we

passed a bill. half measures do not work. it was a compromise by both sides, and it's a compromise to try to trick the american people. our children of all communities are being shot at. it has to stop. i don't know how, but i know that individuals who have mental health issues should not be able to get ar-15 machine guns. >> no one should. >> no one should. but i also understand the reality of this country that i love. i love america, but sometimes you have to criticize things you love. when i'm a jerk my wife tells me. i accept it and i try to be better. america, we are -- we are failing. and it's just -- it's enough. >> and this particular time it happened to be the group who are most affected are all young kids that i don't even know how or

when or how long it will take to come out and be handled in however many ways it will affect each and every child. in this case it was -- everyone that was there. the vast majority of people that attended this parade were young children with their parents or grandparents. and this moment in the middle of their hometown had their parents, and every grown up around them probably just exhibiting the most amount of terror they ever had felt or could possibly experience. and i can't even begin to -- >> we deserve to be safe, we all do, everybody. that's it. be better. >> i appreciate it. thank you very much. you take care. >> thank you. >> thank you. a preview of friday's testimony from a key witness

rein in the former president. >> mr. cipollone said something to the effect of please make sure we don't go up to the capitol, cassy, keep in touch with me. we're going to get charged with every crime imaginable if we make that move happen. >> multiple sources tell cnn cipollone will give a transcribed interview behind closed doors this friday. a spokesman for the committee declined to comment. let's get perspective now from two key figures. john, you were very vocal to our coverage to the hearings last week, calling on pat cipollone to testify. now he's going to, what do you think are the most important questions he needs to answer? >> i think he can tell us a lot

about the state of mind of the president on the 6th, what his actions were, what he tried to intervene and get the president to do and the president didn't want to do. he's there in that heated atmosphere of the day itself. he also knows a lot he may or may not sure that led up to that day. that's what we don't, whether he'll try to invoke privileges and somehow get out of testifying. >> norm, he's -- he was the white house counsel. he wasn't the president's personal attorney. in terms of privilege issues what could cipollone plausibly deny to testify about? >> anderson, the privilege belongs to the current occupant of the white house, joe biden. we know there have already been broad privilege waivers. and according to press reports there's agreed areas of testimony. so all of that being said, the -- the law does provide for some consultation with the

former president. so if we veer out of the areas of agreement, then cipollone can say, sorry, i have to consult and refuse to talk. but the main areas that we expect are things like that violent intent on january 6th, the january 3rd meeting, the corruption of doj, and the other issues that have already surfaced. i think we'll hear about those. >> john, obviously a lot of comparisons are being made between your testimony during the watergate hearings and cipollone's testimony. are they fair comparisons? how important do you think cipollone's testimony will be? >> anderson, i think the two of us are coming at this issue from very different points of view and state of mind. i was somebody who was still trying actively to end a ongoing cover-up of elicit activities at

the white house. and it wasn't just a bungled break in. there were whole categories of things that described what had gone on and put all of it in context. and i thought that need today be out. it was not good behavior for a president. it was unbecoming of white house. so i wanted to get that out. cipollone, on the other hand, from what i can see wants to tell us as little as he possibly can and not look like he's an obstructionist. so he's walking a fine line of trying to not offend his potential clients down the road, which i don't know how you do. i would think that helping the democracy would be the best thing he could do. and what would help democracy the most is to explain his behavior in great detail. >> norm, separate but related to the committee investigation, the fulton county d.a. in georgia said today she would not rule out a subpoena for the former

president to interfere in the 2020 investigation. and lindsey graham is fighting to fight a subpoena. can he get that squashed? >> anderson, i don't think they can. the founding idea of america is -- it's expressed in the constitution and in our laws including georgia state law is that no person is above the law. these activities that president trump and allegedly lindsey graham are engaged in are political activities outside their official duties. i mean, it's not part of the job description of the president of the united states to overturn a legitimate election. nor of lindsey graham as the republican secretary of state in georgia says to want to throw out mail-in ballots in democratic counties. so i think that they do not stand good odds of quashing the subpoena for graham that we know about and the one that may be

coming to trump. >> normizen, i appreciate it. john dean, as well. thank you so much. coming up startling revelations in a new report about what went wrong in the mass shooting at robb elementary school in texas. this whole cover-up stinks. a live report from san antonio and an interview with a teacher who was shot, spent more than an hour laying in pain on the ground waiting in the room with the shooter wondering if anyone would ever come to save them. lemons. lemons, lemons, lemons. look how nice they are. the moment you become an expedia member, you n instantly start saving on your travels. so you can go and see all those, lovely, lemony, lemons. ♪ and never wonder if you got a good deal.

a new investigative report of what went in the police response to the mass school shooting in uvalde, texas, highlights missed opportunities to confront the shooter both inside and now outside the school. the study out of texas state university comes the same day the state legislature says the current uvalde sheriff, has, quote, refused to testify in its investigation. joining us shimon prokupecz. shimon, first of all, just what are the headlines on this? what's the latest? >> reporter: so, new revelations here kind of in the sense, yes, it paints the picture of complete chaos, of law enforcement not in charge of scene. a lot of what we're hearing and have heard about. but one significant piece of information they've been able to learn is there was actually a uvalde police officer who had the gunman in sight, in his rifle, he could see the gunman, could have taken the shot and perhaps taken out the gunman but

he was waiting for a supervisor to give him permission to do so, which is not necessary. it's not needed. but by the time he spoke to his supervisor the gunman had already been gone and was able to get inside the school. so certainly, anderson, a missed opportunity there. and that's what this report touches on, a lot of the missed opportunities. >> and where does the investigation stand right now? >> right. so what we're waiting for now is for the texas officials, the house investigators to do their investigation. they're waiting for more testimony. they're trying to get the sheriff, the town sheriff to come in. he's refused so far to come in voluntarily, so they're ordering with a deposition for him to appear. so that's significant. and that could perhaps be the next place where we get information. of course the texas department of public safety continues their investigation as well as the district attorney. >> why in god's name would a

sheriff refuse to testify? >> this is really significant, anderson. this is a top law enforcement official for this town, and for some unknown reason he's refusing to testify. his deputies, his sheriff deputies were at the scene that day. it's highly questionable why he's doing this. it's certainly suspicious, but we don't know. we don't have the answers to that. >> i understand you were able to speak with a teacher who survived the shooting. i just want to take a look and listen to that now. >> i started seeing, like, the sheetrock fly off the walls and stuff like that. and that's when i told my kids i don't know what it is, but let's get under the table. >> he was the only survivor from class 111 at robb elementary in uvalde, texas. after a month in the hospital ten surgeries from bullet wounds to his arm and back, he's finally back home and talking

about the day that ripped so many lives apart. >> i was getting the kids under the table. i turned around and when i turned around i saw him. but i just saw like the shadow, and that's when i saw the two -- like the fire and i ended up on the ground as well. >> reporter: and so you get hit and you go down. and what's going on in your mind at that time? >> i'm just thinking and waiting for somebody to come and save us. you always think, you know, something bad is happening that the cops get there so fast, they rush in and they help you, you know. and i was just waiting for that. i was waiting for anybody -- anybody to come save us. >> we now know it would be a long and agonizing 74 minutes before police would enter the

classroom to kill the gunman. >> he did a lot of things to make me flinch or react in some way. and that was one of them, where he -- he -- like as i'm laying down either like this or like this tapping it, but it was splashing on my face. >> the blood? >> yeah. >> was he trying to see if you were still alive? >> i think so. >> you're laying there for over an hour, right? and no one's coming to help. what do you think of that? >> that they forgot us. i mean they probably thought that we were all dead or

something, but -- if they would have gotten in before, some of them probably would have made it. >> reporter: it's a question many are struggling with. as precious seconds ticked by, could lives have been saved if officers acted sooner? 19 students and two teachers would lose their lives that day. the subject of multiple ongoing investigations, it's being called one of the biggest law enforcement failures in recent memory. officers feet away on the other side of the door. >> a lot of the law enforcement failed. because they take that oath to protect. i was in there to protect the kids, but i had no bullet vest or bulletproof vest or any tactical gear that they use. and they had everything. >> reporter: when did you realize that the children around

you were dead or not going to make it? >> after they shot him. and the border patrol said anybody get up, let's go, let's go. like try to get the kids up. nobody moved but me. and then somebody else said there's children under here. the children were dead under the table. there was nothing i could do -- >> your children ?

>> yeah, my children. >> i cannot -- i cannot believe the killer is splashing this man's blood in his face, taunting him to see if he's still alive. so if he could shoot him again while police from multiple jurisdictions are standing out in the hallway heavily armed for more than an hour we now know. and i mean the mayor i think yesterday called it a cover-up. i mean it is a -- this is not a question any longer. this has just been from the get-go they have been covering this stuff up from the earliest statements that they made, whether directly lying about it or trying to focus reporters'

attention on other activities that day on anything but the most important activity, which is why they didn't go into that room. >> reporter: and anderson, why didn't they go in that room and help these people? i mean listen to this teacher's story. it is horrendous. it is so painful to imagine that law enforcement, police officers that are trained to save lives, that are trained to go in, they allow him to stay in that room for so long laying on his stomach, he's bleeding, barely breathing, and he thinks that's what saved his life ultimately because that's how the gunman thought he was dead. he didn't realize he was still alive and breathing. it's painful. you know, i really wanted to talk to this teacher because i think the story he has to tell about the pain such violence causes and the way he was able to survive it, and the way he's able to live is an incredible, incredible story. but also the failures of law

enforcement and the police and the story he tells here is so, so important, anderson. >> you know more than 20 years ago columbine a teacher was shot to death and died not immediately. he bled out while the police were forming a perimeter, waiting for a s.w.a.t. team. and that was more than 20 years ago columbine. and police have learned a whole lot more since then. and everybody knows they don't wait any longer. and yet someone made the decision to wait, and we still don't have the answers on exactly what happened. and it's very frustrating. and no teacher should not have lain there. we've learned the lessons to make that not happen again. shimon roprokupecz, as always i appreciate you staying on this. they want it swept away, they want nobody paying attention. up next a look at how teachers in another state prepare for the possibility of school shootings and active shooter trainings part of a simulation drill. more o on that and details ahea.

middle school in utah. and because of all the school shootings in this country -- >> it's just super sad that it could happen anywhere. >> reporter: -- she's considering taking a gun with her to school. >> you just want to make sure you're not interrupting this slide right here because if you do it won't fire. >> reporter: katie is taking a six-week course in utah created by the utah county sheriff's office. to train teachers and other school employees to deal with the 35possibility of an active shooter coming into their schools. >> where the shooter is pointing the gun everywhere else around them they are vulnerable to attack. >> reporter: with more than 40 educators taking the six weeks long teachers academy which includes lessons on disarming an attacker. here's katie taking her turn. some of these school employees say they do plan to bring a gun to school. but it appears that most like katie are still just considering it. either way utah law permits it, so the sheriff who created the

program says since it's allowed, he wants teachers to get the proper training. >> we're not asking hem to do our jobs. we don't want them to do our jobs. we want them to lock down, but at the end of the day if you chronfront a gunman, they are there to kill you and your students, what's your plan? so the whole purpose of this develop that plan. >> you know he's there. stay on him. >> on this day, the educators go into a vividly realistic shooting simulator. >> keep your gun on. keep your gun right on, right on. there you go. >> reporter: the scene is a school. you will see actors playing the students and perpetrators. it's easy to forget it's pretend. katie and emily haskell, the teacher partnering with her, are taught to teach if deescalation doesn't work and they have the shot.
