>> we don't know how long he's been thinking about this, but we do know how long he's been planning and implementing his plan, over the last two months, june and july, is when he bought the guns. on july 2nd, cnn has obtained this receipt to buy tactical gear from an outfit in missouri. it included an urban assault best, a triple pistol magazine, a magazine pouch and a knife. all of them specified ordered in black and all of them ordered second-day air. >> i'm just looking at the fire power. 3,000 rounds. it's unbelievable. is there anything on this guy which would explain why he did this? >> well, we've been covering all the usual suspects, the courts, any kind of court cases, arrest records, girlfriends who would post something online, if if he would post something online. we've been down this road, we've seen the youtube videos that are posted. we've seen none of this. all we're getting is that he was a pretty good, smart student. >> it happened on opening night. do we know if he planned all along to have this happen on opening night? >> we learned from ray kelly, the police commissioner of new york that his hair was dyed red and the guy called himself the joker and obviously there's some connection with this movie and he timed it to be opening night. we at this point have no idea what was going on. >> it is unbelievable. the country and the world shocked by this and we're learning new information. drew griffin. >> the police chief spoke out just a short time ago talking about how officers reacted and really talking about the heros and at one point, he broke down and really become emotional. take a listen. >> our cops went through a lot. as i told you this morning, they rushed people out of that theater into police cars. i've heard some compelling stories. one of the things we are working on is how we're going to deal with our own trauma. >> and no one was spared. no one. the victims ranging at age from at least one infants to adults. one of those killed 24-year-old jessica ghawi. an aspiring sports journalist. just last month she narrowly missed crossing paths with another gunman. in that instant one person was killed and seven were injured. she tweeted just before the attack. movie doesn't start for 20 minutes. her friend with her was able to make it out alive. >> he was very fortunate to be alive. because, i mean, that shrapnel, those bullet particles could have gone anywhere and hit some vitals and killed him instantly. but it didn't. his guardian angel was with him for sure. there's no doubt. >> well, jessica wasn't as lucky, unfortunately. tonight her mother greefs. >> i'll never have her to hug again or get a text message again or get a funny facebook picture. that's the hard part right now. just knowing those are things that i'm never going to get to experience again. >> joining me now is jessica's brother jordan ghawi and peter burns. it hurts me to hear that. i can image the pain going through your heart right now. >> my family and friends, there's been out pouring of support. >> we're so sorry for your loss. when you heard the news, where were you? >> i was in san antonio, in my bedroom asleep. i got a phone call from my mother and there was some hysterics and i got some news that my sister was shot. i spoke to brad. >> just speaking for the people at home, i can't even imagine how you are able to stand at this moment. i personally think i would be in a hospital under medication right now. how are you able to be so strong? do you want people to know how good a. >> it's a testment to my family. and the community. they've powered out to us. and right now they're focusing on her life and celebrating it and hopefully getting the other victims out there and celebrating their lives as well. >> and peter you stood there before the show and telling happy stories about jessica. you zbies were saying if she was here she would be touching every button and knocking everybody off the air she was your intern? >> i worked at the station here and when i moved here to denver i really enjoyed the city and she wanted to progress her career and she said should i move out there and do it and i said absolutely. that was the thing his sister was always about was taking a risk and pushing herself. she did that and moved her with no support system. >> followed her dream. >> followed her dream. >> that's how people who are successful in this business, they're tenacious and curious. i'm looking here, jordan you've been candid on your blog. you're big into social media and you said while still administering first aid, brent noticed that jessica was no longer screaming. he advised that he looked over to jessica and saw what appeared to be an entry wound to her head. what kind of reaction, what does your family think about you sharing this information online. >> i've been a firefighter paramedic for seven years. so i'm somewhat numb to some of this. and i also believe in full transparency. i don't want to hide anything from my parents, family or friends and they need to know what's happened. it's better they find out through me than through anybody else. >> we also talked about what happened at the mall. she came very close, she had a brush with death and i remember that shooting because i was on the anchor desk and. she was there and got a funny feeling. >> it was weird because when she came back in town, it was almost she used it as motivation. just like you know what, okay, i have an another opportunity. i'm going to make it every single day. one of the cool things, we sat face to face at dinner and the reason why she called the dinner she wanted to set up a charity for the wild fires that were happening here in colorado and she wanted to set up a way to get hockey equipment to get kids that didn't have it any longer. so the thing that i told jordan this, she looked me in the eye, i don't want my name attached to this. i'm not doing this to get in the newspaper or media or what not. that's what she was. >> if she had a sentence that would sum up your sister. i know her life was beyond that, but what would you say? >> a sentence to sum u7 my sister? >> a pens ernlt i will maintain in my heart forever. the 24 years i got to spend with her. >> thank you. >> thank you. >> if you need anything let us know. we're going to move on now and talk more about the shooter in this incident. we're back in a moment. why not try someplace different every morning?

>> i do believe it was set on a timer especially considered the events that i now know transpired. >> so what is the timer business? it's set to go off potentially when those first responders go in. that woman ended up calling police but they could not respond immediately because they were dealing with the isis at the movie theater. so there was trauma here around the buildings. five buildings have been evacuated. some of the residents were allowed briefly for five minutes, allowed to go back to their apartments and carry out some of their items this evening. this happened just a short time ago. we also spoke to many people who live here in this apartment building. we met one man who isn't just an evacuee from these complexes, he also had a son who was inside the movie theater when the shooting happened. here's what he had to say. >> i think i don't know. i'm still in shock, you know. >> lay it out for me. how did it impact your life in two different essay ways? >> i almost lost my son today. >> of course we're upset. and especially john, because he could have lost luke, you know. luke was at the movie theater and then all of a sudden we find out this guy lives next store to us. the next building. >> this family being affected in many ways and it's a story that we're hearing repeated among many of the family members of the victims. here in the small community we have talked to many many relatives of people who were still in the hospital and they all tell a very similar story. their child, their brother coming out of the surgical room and this evening still in a coma, still connected to wires. i have to tell you that these stories really are -- you can see the anguish in all of the faces of these family members who are simply hoping that their relatives are going to get better. >> you never know what's going on in someone's mind. thank you, we appreciate that. let's talk more now about this 24-year-old student at the university of colorado, gym spellman has been looking into that. >> it's so incongruent, his academic year. in 2010 he finished his undergrad degree in university of california. >> he's from that area? >> from the san diego area. june of last year he comes here to the university of colorado, denver studying to get a phd in neuroscience, not in any way easy. we know he's potentially studied things like depression, substantial abuse, anxiety, things in that realm. but something clearly has changed. because last month he began to voluntarily withdraw from school. we know that the school took away his access cards to get into building. they say he did that voluntarily, but no indication yet why. clearly something was changing in his life especially the last few months as he withdraws from schools and starts buying these guns. >> he had no record except for a speeding ticket in october of 2011. i have speeding tickets. >> i spoke today with a guy in the neighborhood who had beers with him just tuesday night. just sort of an average, nerdy geeky guy. nobody you would consider a threat. listen. >> you see this, knowing this guy is down the street at the bar with me drinking beer and he lives right here and i'm on the next block with explosives, that's insane. >> he's right, it is insane. >> a puzzling picture. a lot more to piece together. >> thank you, jim. he's from the san diego area, and this investigation spreads across country. we're going to go to new york to m migle marquez who is covering this this part of the story. >> they want to paint a full picture of who mr. holmes is. several agents and law enforcement types are in san diego speaking to family, friends, anybody who might have information about him. they're looking for computers or physical evidence. same goes for riverside, california where he got his bachelor's of science in neuroscience, speaking to his professors and school authorities there and any friends in that area. we've also learned that he did visit a pawn shop in san diego in the last few months. he was asking about weapons that he might use for home protection. they recommended a glock, they romd a shotgun, two of the weapons he had on him last night. don? >> the more you find out about this, just the more disturbing it gets. and all of this miguel as you said, a nationwide, a hunt here to figure out the clues to the motive. the police here, as far as what we're hearing, think they that he ablthed alone. >> it does appear that he acted alone but they want to paint as full a picture as possible, because they want to understand whether there was something they missed along the way. they want to understand what his motives were and where this person may have got the ideas and started to go wrong. but more than anything, they want to figure out if there was some way to have stopped him before any of this happened. don?
