The staff did a Boston hospital today paying tribute to a cardiac surgeon shot. By a man inside yesterday doctor Michael Davidson being remembered. As an inspiring surgeon devoted to saving lives. Hello everyone I'm Michelle Franzen in New York the suspected gunman in this case is also dead police say he turned the gun on himself after shooting the doctor. My staff and doctors at Brigham and Women's Hospital in Boston now starting a news conference to talk about the loss of their colleagues let's listen. Here 3 director of Central Park and Aspen Institute. He's. Pointed. I guess I have to say that I was initially my ex mentor. He came into the training program here. Lives. It to say that I taught him because. Mike as we were talking before it was almost always the smartest man in the room. But more importantly. You know people at these kinds of things. Usually talk very very well about person who's not here and the person talking about that you all should be absolutely assured. That Michael Davidson was one of the kindness. Best. Positions a man that ever walked from the surf. We knew that his patients knew that. His family knows that. But I think he would also wants to. Talk about him not just as a doctor as a man. And Dan we're talking about an incident a few years ago and that I guess I have to brings them into this Mike and I. We're asked to go to Japan. To give a series of talks. And actually a friend of mine who was ranging assessment codes that you've always young and aggressive. I do ethics religion would like to go and speak and I think I was sure Mike Davidson my good friend. Oh my teacher. And we got a notion a notice of what we're supposed to talk about I was assigned topic that I knew very well. I was assigned a topic that. Number one he knew nothing about. And number two. Japan was the world appeasement for the treatment of this problem. So he called me and who is an expert in this procedure and said you know Dan Dan what do Y do. And there are moments that might. You're Smart you could talk for twenty minutes on any subject let you know anything about it and I. And we got through it we had a great time pitching a lot. Michael Davidson gave as good to talk as any other person who had planned the subjects spent tremendous amount of time. Think about it. Teaching. Oh I've seen them. Go absolutely to the map towards patience people alive today. Who collapsed in the hospital that night to simply a war. And he didn't treat them just as people he kisses his patients he treated them as people became intimately and say. Hi I'm doctor Davidson said a Mike Davidson. He was I want the patient's doctor decisions peer educator and I'm and friend. If you don't stop me I could go hours. That college there. I'm Dan Wiener thrusters and has very him. I first met my he was actually a mentor to me an instrument training here I'm back in 2000. But our relationship quickly through developed into a close friendship. Mostly because of our extracurricular activities Mike and I. Or both. Really enthusiastic about music and playing guitar and in fact we. We ended up joining a band forming a band together. And you know so that's so yesterday were playing. Regularly every every Sunday we get together. And as well. And we would get to practice. Practice in the in the basement of this house. And then we would turn our hands up so loud. Sometimes and I really just doesn't believe it is we are really you know we always. Her painters and our phones and we put them on the counter as the music was so that we wouldn't necessarily do that to hear it but we can see it ring or vibrating and inevitably that every rehearsal we would have to stop in the middle of the songs to pick up the page and answer call. And and Mike. Mike was an incredible friend. And incredible father husband. And and and an amazing lead guitarist. And and I listen. Collie. Hours. And characterization laboratory here. Of course quality of life. I probably have like those least one this group. Can this institution 2007. Line for that night in my constituents that here. Dad. Might. Was unique in that. He would not only cardiac surgeon that was it fully trained international cardiologist which is which are two very different. Different specialties two very different skill sets. And of course I got here it never heard of such a thing why would somebody want to do this something that take your time alive to learn something completely different. But I think that and bought into Mike wise he is a visionary and saw what was coming down the pike it means you. We were going to be looking taking care very complex patient in a completely different manner. And we have ever thought about doing and that is using hybrid technique between surgery. And international cardiology. But to do that here the cost a lot of barriers. He had to. Give up a lot of his own personal sacrifice. Time. And and he do this all for a goal of building new program along with. Doctor Eisenhower. Whenever colleagues who's since left the station Frederick well. And he knew that this is the way we're going to be taking care patients in the future I think tanks it is innovative mind. Is his burning desire to push things along and I think it's an incredible skills that. We have developed a very. Strong program and hybrids. Surgical intervention approach is written here complex heart patient. But you know that again is just the technical side of things you're gonna hear a lot of might is his exceptional. Skills with hands. And is an incredible. Brilliant stage is to break down any problem very quickly and think about clever ways of dealing with it. But it's rare that you find somebody who has all of that and can still be human being at the same time. And I can pull up mine phone right now you at least twenty emails. I've gotten from patients just in the last 668 hours. Patients that we care for jointly and beyond these patients are incredibly ill patients and some of them. Didn't make it through whatever treatments we offered them. Yet the outpouring of support and gratitude to all the time and might gain in these people in their timing need. Was was just so strong that after hearing news. What it happened they felt it needed to reach out somebody. Two had shared experience with their loved ones and I myself and that that has been incredibly. Touching to mean just to reminder we was. He did have a silly side that again I have seen. In this hand in front of forty somethings trying to relive or twenties and maybe not doing so well. We it. But. I really. Can't imagine. Combination town. And humanism. That. Well that any institutional -- opportunity to work with. Future it's just tremendous. You cannot we know how hard that's it's for and we appreciate you. Being willing to Sharon asked to do you have anything else that you wanted to share before reopened it up to question. I just think it's. Yeah it's really remarkable how old. Mike has effective. His colleagues in medicine not just here this institution but whole room. World. Sometimes we get very insulated we worked very hard to your own institution and our own sort of way. And you forget. You know we're all care providers in some way shape form and everybody. Is bound by that. One thing when you see patients in the office and do operations. Taking care of people like was. He was caring. Take everything about about all the technical aspects of. Care. People so we'd like to open up for questions yes she's going. So I actually did speak with Patrick Davidson's wife earlier today she did allow us to provide some information about the surgery. Here because it's been a lot of misinformation firstly her name is Terry Halperin. THE pounds PER. She is author of physician. Their data Kate. Is nine years. Their daughter lived is seven years out. Their son Amos two and a half. And Terry is seventh. With. Another question. I. Oh yes. All of us all of those things but I have to come back to you would demonstrate to his patience how much he cared about them. There was never a day hey. Perfunctory. I'm gonna go in and see this person for a couple of minutes it's. Guess we all get that way it's like oh I'm busy then we go in sit down and then fifteen or twenty minutes they were thirty minutes later. The conversation would be over only when he was satisfied. The person he was speaking with. Hat and well sir. And it wasn't he just couldn't do it any other way. And maybe I'm not crazy very well. It. We all know. People in this room who take care we all know what I call doorknob doctors people who were talking to you with their hand on the door and operated to leave the room. And Mike was exactly the opposite that. Hugh freeze that. Perfectly to Fred I'm gonna Cody and his canoe mind. Our folks here seminary people questions at the people who and listening in on happen offensively and respond to expect he's got. We're. To the first question is doctor Morris or anyone on the panel looking over his childhood how he grew up. Where he grew. I guess I defer that that challenge details to whatever the family feels comfortable. He's. I was yeah it's that's where our paths first crossed the Princeton always been a great deal more time actually slips when that here at the break. So the question is could someone describe that hybrid OR that he was involved in pioneering. Maybe I'll have you all right you are really after starting out so. The treatment of cardiac disease. Has in the past been divided into three parts medical medicines. Surgical. Making incisions and repairing things surgically. And then eventually using catheters to treat coronary disease. As we need mentioned Mike was a visionary and he realized that. In the future. Patients. An ambulance. And you've been listening to a press conference out of Brigham and Women's Hospital in Boston colleague speaking about there. Colleague and friend. Doctor Michaels date Michael Davidson who was gunned down yesterday. Many questions of course on this still developing story as this investigation unfolds we want to bring an ABC's. Parent teacher ski who's been watching this from the start Aaron we heard. Some very emotional stories about the doctor including that he was a father of three with a fourth child on the way. We're also learning more about the past between doctor Davidson and the suspected gunman. The student this Kerry was the one that the police said came in. Knew exactly who he was looking for went to the second floor of the Shapiro building at Brigham and Women's Hospital in Boston. A home of the cardiovascular senator and and targeted doctor Davidson. Four. Four for what. Though police still haven't said for sure but the booed the wide belief now is that. A pest Kerry's mother had been at one point a patient. Of of the doctor and perhaps he wasn't pleased. With her care she had died and and and maybe he was simply. Distraught. Police say they are still going to try and do some digging to figure out the exact motive here but now that. He is dead the doctor is dead their police are are are really focusing on some of the same stories that we just heard. From those that knew doctor Davidson. And the suspects Steve the scary as you mentioned walked in specifically requesting to see that doctor. Give us an idea of what we're learning about as those moments unfolded whether or not the staff began to detect anything was wrong from the start. Well we know that there was a good deal of panic according to eyewitnesses were people running and and screaming. There are no metal detectors there but Boston Police were on the scene very very quickly hospital security as well. And then it was simply flooded with state local and federal agents that all kind of came together because it's so rare. To see a shooting in a hospital like this especially one as noteworthy as Brigham and women's. And so very quickly police were able to say publicly. At the scene had been taken under control they had the suspect in custody. In truth they found him dead of a self inflicted gunshot wound do we know where they found the body of the suspect Aaron. A couple of doors down it seems from the actual shooting scene and and and that's where you to police as they were doing their searches their door to door search. They had asked the staff inside the Shapiro building to stay in place. The rest of the hospital was not locked down but this particular building was for a time. As police searched and and and one they found the found the body was pretty clear that point that he had taken his own life. And of course we know that Boston of course having come under siege in a very different way during the marathon. Staff within hospitals of course go through drills all the time of how to handle. Active shooter situations when we found out about the specific hospital and drowns. Did it did in Brigham and women's was no different they had also done not active shooter training Brigham and women's was certainly. Among the hospitals but contributed to the effort post marathon. And like many of public hospitals so they've decided that they needed to it to do the kind of training that they put on display and that's why police I think realist Telus so quickly. Part of the reason anyway. There revenue Telus so quickly that things had been secured and that that that that there was no particular harm but it. So scary. A well known hospital. No metal detectors and and and for most hospitals it's that way you go in and maybe you show an idea to a guard but really nothing to stop somebody like this. Somebody perhaps upset with that degree of care that his mother had gotten. Previously from this particular doctor and targeted just the one doctor and and thankfully so. No other shots were fired. Caricatures he thank you very much following this story. And of course you can keep up. With this story in real time by downloading the ABC news apps and starring the story for those exclusive updates on the down. For now I'm Michelle Frandsen in New York.
