dr. henry lee. dr. lee, thank you for being with us. speak to you about your expertise and in your experience, in all the years that you have done experiments, have you ever known the state crime lab to open up in the middle of the night for dna testing? >> yes. in the past we did numerous times. not only open up in the middle of the night, sometimes we work on the new year's eve and christmas and just like a law enforcement officer, police officer, every day they seek just working 9:00 to 5:00 shift, no, it's not. we work around the clock. >> good to know. dr. henry lee, when they say that they took dna from him, would that only be a buccal swab, an oral swab that you do with a q-tip like object? >> actually we have three different type of applicators to collect buccal swab evidence. you're right. some of the media report saliva sample. we are actually not looking at the saliva, we're looking at the cheek cell looking for nuclear dna, trying to extract a dna as a known control. then we have to compare those samples. there are reports o

dr. henry lee. dr. lee, it is wonderful to see you again. i only wish it was in person. dr. forensic investigators be holding back right now? why would they hold back cause of death? >> well, they're not really holding back. basically right now they have to confirm. they have so much evidence to look at. basically this is a three-prong approach of the investigation. one is look at videotape, look at electronic card entry, second one is look at the timeline analysis. 10:10 she was saw. did she have a particular reason to two to the bachlt and what the routine she does? the third one, of course, whether or not she was sexual asalted. if it was sexual assaulted, dna of that. whether her fingernails have tissue material. some individual have some type of injury. of course, her clothes. where's her clothes? any knife injury or any damage? and clothing found in the tile, those have to test whose blood is it? any touch dna? of course, people have to understand, say, her body was found inside the wall. it's kind of misleading because a lot of basement have false ceiling, false wall.

dr. lee, is this definitely a dna case? >> yes. definite. of course, there are other evidence involved. this case, usually, we use a four-pronged approach. the first one is our data monitor. look on the videotape, there are 750 hours of videotape available. also, look at those key cards and activity. whether or not we can find certain that the victim are together. the second thing that we look at is her activity. try to see. because on the videotape, she was seen. after that, she goes to the basement to inject the animal and the person of interest, where's he located? the third thing is any witness available, the last one is physical evidence. of course, police report they collect 250 items of evidence. which, i think, that's kind of misleading a little bit. 250 items, not all the items have scientific evidence value. so the laboratory scientists have to go through those 250 items, try to find the linkage. that's why police chief was correct in this case, probably take a little while until the dna evidence show any connection and try to solv

then dr. lee learned of the arrest.en you heard of the arrest this morning, did that say to you right away there must have been a dna match? >> yes. i know there was a match. of course, it's a relief. >> tonight, raymond clark has been moved to maximum security prison in connecticut and they believe there was only one killer in this case. annie le and raymond clark never had a romantic relationship. clark was a lab technician and they would pass each other in the hallways. today, the family of the fiance released a statement saying we want to thank all of those who were involved in preparations for a wedding that was not to be. for their quiet understanding. annie will live in our hearts forever. i'm david muir for "nightline" in new haven, connecticut. >> and one hopes this arrest brings some brief respite for those families continuing grief. our thanks to david muir for that. >>> we're going to take a break. when we come back, did texas execute an inknow isn't man? that is the question in the case of a father put to d

dr. henry lee, how solid is the evidence on this? do they have this guy at this point? what do they have? >> well, official report, of course, the victim died of a neck compression. and the evidence, basically, there are a lot of videotapes and swipe card records, in addition to, of course, the dna evidence. according to the news report, they found her dna on his shoes and also his dna on her clothing. those clothing material was found on the top of the ceiling tile. this is extremely important. now you have the linkage. you put the victim suspect in a close contact range. also, you put the victim suspect in one location. and that's why they wait until the dna result to make the arrest. >> okay. a reminder, raymond clark is innocent until proven guilty, despite what seems to be a mounting amount of evidence. a criminologist joins us next. back with our guests in 60 seconds. en both have osteoporosis. but we're active. especially when we vacation. so when i heard about reclast, the only once-a-year iv osteoporosis treatment, i called joni. my doctor said reclast helps re

dr. henry lee, who joins us tonight. forensic scientist, renowned forensic scientist and investigator, live from hamden, connecticut tonight. dr. lee, you have such a vast experience in regard to dna and forensic discovery and investigation. hearing what has just been done, that these dogs have been taken into this building that is quite large, the last known building that annie le was seen to go into, what does that tell you? >> well, that's pretty clear. more likely they bring the bloodhound. connecticut state police canine unit would have an excellent reputation. a lot of good trained dog and handlers. so they have to go through each laboratory, every floor, every corner. sometime, you know, have to go to the underground and look for any place because she apparently 10:00 was saw inside the building. she has to be someplace. and they did -- law enforcement did the right thing to have federal, state, local joint task force to work on with fbi, connecticut state police, new haven police to work together. this is a missi

dr. henry lee. henry, thank you for being with us. my first question is -- >> thank you, nancy. >> -- if clark did try to clean up, how could you tell? how could you tell by looking at the dna, by looking at the blood markings, that he was actually trying to clean up? how do you know the difference between a cleanup and blood spatter? >> okay. the blood spatter usually have defined characteristics, have shape and patterns. cleanup usually considers a smudge. if you use water or cleaning solution, now it become a diluted. we as experienced easily to tell. to say i don't understand, your report say police officers saw him clean his cleaning bottles. if the police officer saw him cleaning, should right away stop him, seize the evidence, and the blood spatter, which of course we can use hemorrhaging to restore the pattern to determine that's a drop or a medium-velocity impact spatter, even the impact spatter, then have to have another type of a traumatic force cause some bleeding. >> so, dr. lee, my simple rudimentary interpretation of wh

. >> so, dr. leemy simple rudimentary interpretation of what you said is, with blood spatter, now a theory is emerging that he struck her before the strangulation. that could explain some of the blood. you would see as if you had paint on your hand and did like that on the wall. >> yes. >> as compared to cleaning it. you would see a smudge mark where -- >> right. >> okay. i got it. very quickly, dr. henry lee, can you get rid of dna with, for instance, a cleaning solution? >> yes, in fact, yes. uv light can destroy some dna evidence and bleach solution can destroy some evidence. however, what this case so important is his clothing, boots, from her dna. >> exactly. >> her clothing from his dna, depends on the inner layer or outer layer. the most inner layer clothing on his dna become even more important. >> to a neighbor of raymond clark's, annmarie goodwin, a special guest joining us tonight from hamden, connecticut. thank you for being with us, ms. goodwin. what was your impression of him? how stunne

and certainly to me some of these men along with dr. lee robertson in chattanooga that we were with, they just will never leave my mind or my hear they meant so very, very much to me and i know they did to you jack. >> oh rexella, we had some great times with some of these ministers and by the way, we held 800 local church csades, a week a pce, and then we held over 120 united crusades with all the churches coming together and 10 million attending. but i remember these were church crusades and they were two of the first mega churches in ouray and dr. mcgee had thousands attending there and wh we had a crusade with him in los angeles, during the greatest flu epidemic in history, we didn't know where to put the people. and he gave me the that title, the belgian bible bombshell. i've been called, as i said earlier, the walking bible before that. but then we were with adrian rogers and you know he and dr. criswell were the two men in the southern baptist convention, for both of them had been presidents, who brought in the teaching of the raptur

dr. henry lee, who helped advise the forensics team, said this arrest likely came after a dna match. when you heard of that arrest this morning, did that say to you right away, there must have been a dna match? >> yes, i know dna had a match. and of course, it's a relief. this case is a sad case, a young lady was murdered. >> reporter: now, the police chief here reiterated again today that he does not believe that le and clark had any kind of romantic relationship at any point in the past. in fact, charlie, he described the relationship this way. she was a ph.d candidate, he a lab technician. they would pass in the halls here. >> david, thank you. >>> a verdict was rushed late today in a trial of a high school football coach accused in a player's death during a tough practice on a hot day. and this is a case that was matched by high schools across the country. a jury in kentucky found jason stinson not guilty in the death of the 15-year-old player, and deliberations that lasted only 90 minutes. eric horng is in louisville. >> reporter: the coach ordered the students to run sprints. >

. >> reporter: and dr. lee points to the access cards, swiped to get from room-to-room in that building. computer records show that annie le entered a small room off of the lab in the basement and never used her card again. reports say that raymond clark was swiped into that room, too. and raymond clark's co-workers have now begun to come forward, telling police clark was a control freak. who viewed the lab and the mice as his territory. and abc news has learned that clark had expressed his frustration over dirty mice cages. but officials have not given a motive. two of raymond clark's high school friends told me, he was a popular baseball and football player, friendly. but they are aware of the reported evidence. when you heard the mound of evidence, now -- >> i'm torn. i think so highly of ray. and to think of him doing something like that is -- you know. i don't know. >> reporter: hard to reconcile? >> yeah. >> reporter: raymond clark's friends who played softball with him the day that annie le's body disapp

dr. henry lee served as state police commissioner in connecticut.w he runs his own forensic center at the university of new haven. he says those access card have provided a timeline inside that lab building on the last day annie le was seen alive, revealing any opportunities a suspect would have had to harm annie le. >> what do those cards tell us? >> we have an opportunity that we're going to be together. >> there are reports those swipe cards put them in that room, the last room where anyone was. >> that's crucial information. >> sources tell us there are texts and e males between clark and le, that clark had complained to le that the cages were dirty. after days of following raymond clark, tuesday night detectives moved in with a warrant to obtain dna samples were clark. they tried to question him but he quickly invoked his rights to attorneys offering little to investigators. then 3 a.m. went morning they let him go. criminal experts say it's not uncommon to let a criminal experts say it's not uncommon to let a prime suspect go after questioning

dr. henry paul, adolescent psychiatrist and author. also with us former criminal investigators and director of defend university steve cardigan and henry lee following this since day one from the "san francisco chronicle." starting with dr. henry paul on this one, what could this lady be thinking as if jaycee dugard doesn't have anything else to be concerned about like putting her life back together. >> it would be humorous if it wasn't so ridiculous. i think she is very angry the police have investigated her house for some reason but to say something like that couldn't be further from reality to tell this woman, who we think suffers from a stockholm syndrome implying horrendous disassociation and stress disorder to tell her to come out and tell the truth is almost like a by var concept. >> yeah, it is, almost to the point of unbelieve -- the height of selfishness, right, doctor paul. >> -- her husband, himself, had some trouble and she feels rather violated. you know, maybe she believes because she knew the young girl, the young girls and jaycee were living with they man there, is no maybe she really doesn't understand a stockholm syndrom

news & world report" and dr. lee, the assistant clinical professor at yale school of medicine and author of "every patient tells a story." welcome to you both. >> good morning. >> dr. sanders, let's start with you. what caught your ear as a practicing physician in president obama's speech last night? >> well, first, it was great to hear that the discourse is going to get back on track and we can talk about the real problems that face us as we take care of our patients on a daily basis. so that was really great to hear. i was really glad to hear that he's going to protect people who already have insurance. i have a patient who had the misfortune of having a heart attack 20 years ago. now he can't get insurance. his cobra ran out after he retired early. and he has five more years to medicare and he can't get insurance. that shouldn't happen. and i think that the obama's -- the reforms he's suggesting will make sure that that doesn't happen. and that was very exciting. >> yeah, the one thing i think many americans are s

for dr. lee, sir, could you tell us more about your plans where you had a slide that said lessons learned. it's coming up in september here in washington, d.c. would you tell us more about those plans, sir? >> they are series of lessons learned for the organization. the first one is barbados for the caribbean regioreceive what actually happened. the second one is the week after, again it's technical meeting mainly related to the aspect which will be held in ami for all the the countri of the region. and the third one is internal one at headquarters on the third week of september which is actually going to address how the headquarters responded. the third one which we are involved, which i am involved in, is an internal review. in addition to that we have identified a consultant to do an analysis of the organization response and he will be attending all these meetings and will also prepare reports for the director. >> i'm fromcare -- cairo, egypt. when will it vaccine will able? i will have about

lee metzler and heidi lynn childs were apparently shot to death. the campground is about 15 miles from the tech campus. >> out to dr. marty mckerry.he cause of death is by shooting, i'm hoping against hope this was a quick and painless death. what can you tell us? >> they'll be looking at particulates of gunpowder at the actual entry site. they'll be looking for the trajectory. they'll be looking at autopsy for any bruising. and they'll be able to tell whether or not there was a struggle. i suspect there will have not have been any type of struggle. >> back to mike brooks. mike, what's your analysis? >> you know, nancy, right now with no good evidence that we're hearing about, i'm sure maybe the sergeant knows a little bit more, but i don't blame him for not saying anything. but right now it's just what we're doing right now. getting it out into the public's view because a lot of times, nancy, as you know, a lot of times people think -- you know, don't believe they see anything, but they really do. >> sergeant childs, how is your family tonight? >> they are feeling the pain. her sister's very close, her two brothers very close to

dr. frieden also talk about the negative income tax? how does that differ? >> yes. i wro a column on his death a couple of years ago a title submitted was but in friedman lee a bleeding heart? and the time to change the type of the always changing. sometimes they come up with better one-third the nice thing about being able to compile collection in my column was i got to put the titles i wanted on each one. so yes, he proposed a negative income tax. if you don't learn any money the government pays you rather than you pay the government. and in the more money you earn, we take it back some fraction of each dollar earned in the form of taxes and so yes, it was the precursor to the current income tax credit which is the most widely copied welfare program the u.s. has come up with countries around the world have begun adopting this. it is a way to make it more attractive to employers to hire additional low-wage workers. that is one effect of it. and also gives people higher incomes than they would earn just under wages alone. so it is really a great cause. and milton friedman was the original designer of it. >> milton friedman i can't tell you how many times he has spoke

jackson lee: i thank the distinguished chairman and ranking member and proponent of this legislation, my good friend. i rise in support of this recognition of dr. norman e. borlaug for his many contributions, raising the bar, if you will, on the horrific impact of hunger in this world. he engaged in groundbreaking scientific research and personal compassion to help save over a billion people from starvation across the world. as a member of the board of directors of the congressional hunger center, i am deeply saddened by his loss. but he deserves countless accolades and none of these accolades do full justice to the greatness of his achievements in alleviating hunger. dr. borlaug's work was extremely important to the effort of my former colleague, congressman leland who represented my district until his untimely death, trying to alleviate the hunger in ethiopia on the basis of the continuing drought. both dedicated their lives to fighting hunger around the world. for 20 years dr. borlaug was a distinguished professor of international agriculture at texas a&m university. i believe he had the thesis, teach a person to fish versus giving a person
