>> reporter: well, the police chief would not comment on reports that there had been some e-mail exchanges. this based on, according to various reports, on the condition of some of these cages that contain the mice. the police chief wouldn't comment on that at all. but that gave us some indication into some of the conditions at work. he was the lab technician looking after mice. this police described their relationship. he was the guy who would clean cages that these lab mice -- where they were held, she was the ph.d. student who did research in that laboratory in the basement of that building at yale where her body was found on sunday. >> mary snow, mary snow, what is he doing bunked up at the motel 6 when he has an apartment that he shared with his fiancee just a few miles away?

is the bail set? and is that a tattoo i see on his arm? >> there's a tattoo on both arms. it was as strange of court appearance as you can imagine. connecticut courts, like most courts, usually drag out. this was a very quick affair. they cleared the courtroom. took out all of the traffic violation people. they brought in all of the reporters. we all got a seat. and within a matter of ten minutes, they brought in raymond clark. there was also a camera and microphones in the courtroom. this for a first appearance. now, clark was wearing a striped polo shirt, bare arms, khakis, no belt and chain irons. and, in fact, we could hear the irons clanking as he came into the courtroom. that was about the only sound. now we couldn't and we mark on his arms. the shirt would block any marks anywhere else. there was a noticeable bruise on his face. clark really had his head down throughout the three-minute proceeding. said almost nothing, except to acknowledge that he did understand his rights. bail's set at $3 million. and he'll be back on october 6th. >> al jones, it's my understanding that he has already given a statement to police. and now if this is correct, he's locked into this, by the way. that he blames the defensive wounds, to my understanding, his bruises and scratches on the arms, the chest, the bare chest, the back, under the right eye. there's also bruises, scratches and abrasions. he's blaming all that on his three cats and injuries from a recent softball game. have you heard those reports? >> he did play softball on sunday. in fact, police surveillance teams were on him at the time. they had sent a narcotic's unit to follow him since sunday. a narcotic's unit, as you know, are covert by nature. so on sunday they were doing it undercover. and they did see him playing baseball. he did go to a local fair. did normal sunday things. no word of any cats. >> okay. >> and neighbors didn't know how many cats he had in his apartment. >> al jones, is it true that at this jailhouse -- i know mary referred to it as maximum security -- but is it true that he has access to yoga classes, poetry classes, dance classes, a whole list of amenities, al? do we have that list, norm? >> i'm not sure what he's -- what he has at his disposal. it is a higher level jail. >> art classes, upholstery. step aerobics sculpture. dance, poetry, foreign language. what about it? let's quickly unleash the lawyers. we are taking your calls live. susan moss, john burris, michael mazarelo. susan moss, step aerobics, yoga, did you hear that? >> that's -- i don't know whether it's -- it's some sort of club med or it's a prison. but we're going to see how this lab tech likes being in his own cage. if they had enough evidence to bring him in and to make that arrest warrant, then i think they're going to make good on it. what would you say if i told you that drivers... who switched from geico to allstate... saved an average of $473 a year?

"the hartford current" reports those records indicate clark was the last to see le alive. >> the state medical examiner says the 24-year-old le was strangled to death. >> what happened here could have happened anywhere. it says more about the dark side of the human soul than it does about anything else. >> straight back to al jones, reporter 1010 wins, in court today when clark appeared in full shackle for an outloud reading on charges of murder one. so you got a look at him in his khaki pants and his nice-looking polo shirt. what do those tattoos say on either arm? >> they really didn't say anything. more of a herringbone encircling his biceps. both of them halfway up the arm. with the short sleeves, you could see it quite clearly but nothing spelled out, no message there. >> wait, what's a herringbone? >> herringbone, like a -- the diagonal in a pattern, sort of like a sport coat but it went around his arm. >> so it's just going around just below the elbow? >> yeah, just a band between your elbow and your shoulder. >> what, to like, show off his muscles? >> if you like that kind of thing, yes. >> okay. good to know. we are taking your calls live. but first to jean casarez, legal correspondent with "in session." jean, i want to find out about two things right now. what can you tell me about this former girlfriend that states he terrorized her and harassed her, made her have forced sex. that's rape, okay. everybody keeps saying forced sex. that is rape. no charges ever filed, number one. and number two, i want to find out about these e-mails between him and the murder victim. what do you know on either of those two topics, jean casarez? >> reporter: all right, number one, nancy, the incident that you're talking about 2003, raymond clark was in high school. he had a girlfriend. she wanted to break up with him. he retaliated by writing on her locker. the police were called in, the school called them. end of incident. then she and her mother went to the police station and she told the police that they were boyfriend and girlfriend but he forced her to have sex. now that is what you are equating with sexual assault, rape. she would not fill out an affidavit and so it was case closed before it even began you go but she has reportedly said when she saw he was a suspect she relived that 2003 incident. number two, what was your other question? >> jean? >> yes? >> we're showing everybody right now photos that we have obtained today of raymond clark from his high school yearbook. went up there to try to find the girl to find out about this pattern of violence and harassment of women. there are the shots that we obtained. i wanted to find out about that and i wanted to find out about these e-mails that went back and forth between the 90-pound victim, annie le, and this guy now charged with murder one. what do you know about those e-mails? >> reporter: it's being reported that these text messages or e-mails had maybe two different subject matters. one being that he who maintained the cages and the animals was upset at her, annie le, because she was leaving her cage in disorder or dirty or not in the condition that he wanted the cage left in. but i think even most importantly was it's being reported that there was a text message the morning of the day she went missing. asking her to meet with him at the lab. that they were going to meet together. >> okay. >> and that is evidenced by the key card access. >> yeah i want to talk about those swipes. everybody, you're seeing photos now of raymond clark that we obtained from myspace. to editor in chief "yale daily news," thomas kaplan, who's been with us from the very beginning. thomas, welcome. i want to talk about those swipe cards. putting them in and out of the building. no less, maybe more than ten times in those crucial hours including after work. >> so it does appear that the record from these swipe cards are sort of a crucial piece of evidence in this case. to get anywhere in this building this is a new building, you need to swipe the i.d. and then a computer system records where you go. so that's how the investigators can tell who was where and when >> and isn't it true that he was going into rooms that he typically had no business in? >> that is what some reports have said, yes, indeed. you've worked all your life. as the decades have past, the promise of medicare has always been there. and aarp has fought to guarantee none of the benefits you earned were ever taken away. today we're continuing that fight by protecting your freedom to choose the doctors and treatments you need. and to have your tax dollars go towards your care-- not insurance company p) subsidies. you've done your work. and we'll keep doing ours. learn more at aarp.org. arrested for murder, police slapped the cuffs on a lab tech and charged him with the death of annie le. >> authorities swiftly shut down this intersection along 372. the operation to arrest raymond clark iii was about to reach a peak. >> about nine police cars coming in with sirens on, road was closed and the back of the motel and at one point we saw them take him now the handcuffs. >> annie le's battered body was found hidden in the wall of the lab basement discovered on the day she was to be married. she had been strangled. >> straight back out to thomas kaplan with the "yale daily news." what can you tell me about sources claiming this guy was a "control freak" at work. control what? he cleaned out the mice cages. what's there to control? and i'm not laughing at that. i had a job where i cleaned the floor, all right? >> yeah. >> so i'm all fine with that. but control what? >> apparently he was very concerned about the -- how people kept their -- their mice, their cages. there had been some reports he got very upset with people who wouldn't player plastic booties. that contributed to why he had a problem with annie. but all of this is kind of speculation that the point. >> but it's my understanding, jean cazares, legal correspondent with "in session." everybody, you're seeing private home video of annie le. products 2005 from abc's "good morning america." there you see her right there at her computer station. jean, let's just get down to the brass tax about these e-mails. didn't he confront her allegedly in some these e-mails claiming she was not following protocol and she responded in a very conciliatory manner, a very nice manner, saying she followed all of the university's protocols to a tee but she was willing to hear what he had to say and open to making whatever changes he thought was necessary. a very kind and conciliatory text message back to him. >> that's definitely what's being reported that she wasn't defensive at all, she was willing to improve in any way she could. if there was anything she didn't do correctly. >> and to you, bethany marshall. psychoanalyst, author of "deal breakers." what do you make of it? >> well, so many times we've seen these men who commit homicide that they fancy themselves the keeper of the rules. remembe
