I also want to again thank the brave men and women who showed their heroism by rushing into a very dangerous scene. Our men and women in our Law Enforcement family. Weve talked about them. I also want to thank this is a big Law Enforcement family. And from the dispatchers who calmly took the first 11 calls to our men and women in the fire department, the hospital. Really proud of the coordinated effort. Again, i want to thank the state police, many state and federal agencies and our neighboring partners as well. I also want to thank the public for being so patient. The mall has been closed a second day. Its disrupted a lot of peoples lives. The outpouring of compassion weve seen in this community, both yesterday here at the mall with neighbors grabbing neighbors and kids and sheltering people and doing the things that loving members of the same community do was really heartening to see. Tomorrow, the mall will reopen, it will be open at 1 00. I want to thank the mall for their diligence, their partnership, working collaboratively with us both through the investigative effort and just in dealing with us to get open as quickly as possible. There will be two memorial sites, so the public is welcome to be involved in that starting at 1 00, one outside the entrance by the starbucks near sears by the fountain.

I certainly appreciate your patience as we do that. I certainly add to the county executives appreciation to the community and all the great assistance we got from our Law Enforcement partners. Ill update you on a couple things, and ill take a few questions. Our investigators today have been busy trying to learn more about why this situation occurred. They attended three autopsies. They spent a considerable amount of time interviewing families, friends, associates of just our victims and our shooter. At this point, and i know this is a question thats on the top of everybodys minds, what is the motive and is there any relationship between the victim and our shooter. At this point, we still have more work to do. We still have more to do. We have no known relationship between the victim victims and our shooters. I would just say this for a moment. I addressed this before, theres still speculation that there was somehow some romantic involvement involving this. We have not been able to establish that. Im not sure where that information is coming from. Its becoming very frustrating for the families of our victims to continue to hear this. So id encourage you to report what we are providing, not other speculation you may hear. I know we appreciate that. The families will appreciate that as well. Theres also been a lot of interest expressed in us releasing a picture of our shooter. In this case he has no criminal record. We dont possess a picture of him. We have, however, worked, and after this briefing, well be releasing a Motor Vehicle administration picture to you and sherry will ar ring getting that to you. We also know and its been reported the existence of a journal that the shooter had. As i mentioned earlier today, we did serve a search and seizure warrant at our shooters house. We did retrieve documents as well as computers and other evidence. We are working through those. There is a journal. He does express some general unhappiness with his life, but i really dont have any other information about that now. Thats something were going to continue to work through tonight and in the days ahead. I know theres a lot of interest in the motive for this. I have as much interest in that as anybody. So i appreciate the frustration that we havent been able to provide that. But our goal is to be able to provide you as Accurate Information as possible. That continues to be our goal. Again, no known relationship between our shooter and our victims. Were continuing to look for that motive. Thats where our focus will be and it will continue into the future. In terms of the mall, we have had a strong presence around the mall since the shooting occurred. We have been working with mall management to ensure that patrons who left personal belongings in the common areas of the mall were able to retrieve that. Weve been assisting with that process. Weve provided grief counselors from our victim assistance unit as well as our partnership with the mobile crisis unit of Howard County. Weve also assisted the mall in getting the tenants, store owners back into the mall so they can get their businesses ready to reopen. Again, nothing is going to go back to normal. This mall is going to be different because of what happened. We all understand that. Our job is to make sure this cornerstone of our community is open. To get to some form of normalcy to investigation why this happened. Ill take a few questions. Yes, maam can you clarify, in terms of criminal history, he has no criminal history either as a juvenile . Do you know of any Mental Health issues . What youre listening to is a press conference outside Columbia Mall. Thats Howard County police chief bill mcmahon, recapping for us. The new information we have is Police Confirm at this hour theres no known relationship between the victims and the shooter. What the police have said that they will do is because the shooter had no previous criminal record, they will release a drivers license photo to us. Theyve also told us that they have with a search warrant gone in and found some type of a journal where police say the shooter expressed some general discontentment with his life. We want to recap what Howard County executive ken ullman mentioned a few moments ago. There will be two memorial sites for the public to visit inside the mall. Again, the mall will reopen tomorrow at 1 00. There will be one memorial site at the entrance by starbucks and another inside the mall by lord taylor. This is a quote from Howard County executive ken ullman who said just minutes ago we may never be quite back to 10 normal, but we are resilient. Again, this is a Live Press Conference outside Columbia Mall. Police saying this is the last Live Press Conference they will have, but they will continue to update this via their twitter as well as their facebook page. We want to continue with our Team Coverage with news 4s david culver who spent the day speaking with the shooters neighbors. Hes live in college park with the latest. David .

I went door to door today, as soon as we got word of the identity of the suspected gunman, i spoke with a dozen neighbors and they tell me police shut down this entire road as they investigated. Hollywood road, tonight gaining all the attraction of its name sake but for all the wrong reasons. There was a police car blocking off hollywood at route 1, another one blocking off the street down there. There was a bomb squad truck. There was a police unit, a mobile crisis unit.

Police say surveillance videos show aguilar took a cab to the mall yesterday, with him a 12 gauge shotgun he legally bought last december.

Reporter she says about six months ago his dog ran away. She found it and returned it to him. He was concerned about his dog. He cared and he was thankful that someone cared enough to bring his dog back to him. Reporter when you hear one of your neighbors is potentially connected to this, how do you even how do you process it . It makes you sick to your stomach that somebody couldnt get help and thats how their life ended. Its sad, really sad. Reporter one of those victims, Brianna Benlolo lives just a half mile from where were standing. But police have said there is no known connection between the suspected gunman and that victim.
