Mother and Baby Murdered; Doctor Death?
COOPER: Well, we turn now to the Entwistle case. If you cannot get it through your head, is that a vibrant young wife and her beautiful baby girl were buried together at the beginning of this month -- buried together because they had been shot to death together. Well, the authorities are having a hard time that through their heads as well. That's why they keep going over exactly what happened and when. CNN's Jason Carroll investigates.</s>JASON CARROLL, CNN CORRESPONDENT: The mystery began here at Priscilla Matterazzo's home in Carver, Massachusetts. When Matterazzo spoke to her daughter, Rachel Entwistle, on Thursday evening, January 19, for the last time. (</s>Voice-over): Investigators have not said how long they talked or what they talked about. The next thing we know in this story happened here at Boston's Logan Airport. Early Saturday, January 21, Rachel's husband, Neil Entwistle walked through Terminal E at the airport. He appeared on a passenger list for an 8:15 a.m. British Airways flight to London's Heathrow Airport. Officials, however, are not saying definitively whether Neil Entwistle was on that flight, could have been on another flight at another time. (</s>On camera): Later that same night, several of Entwistles' friends show up here at the home in Hopkinton, invited for an informal dinner party, but no one answers the door. Rachel's family, who had been unable to reach her, are concerned and call police. (</s>Voice-over): Sunday morning, January 22, Entwistles' family and friends check inside the home. They too look in the bedroom upstairs and notice the unmade bed. But they see nothing out of the ordinary and file a missing persons report. (</s>On camera): In response, that same Sunday night, police reenter the Entwistles' home and detect an odor. That's when they discovered the bodies of Rachel and her baby, Lillian, under the disheveled covers in the bedroom upstairs. (</s>Voice-over): The death certificate says Rachel Entwistle died from a gunshot wound to the head. It says her death was immediate. Baby Lillian died from a gunshot wound to the abdomen. Her death occurred within minutes. The medical examiner cannot pinpoint the exact time of deaths. Investigators say it appears to have been sometime between Thursday and Saturday. That does not explain how both family and police missed the bodies in previous checks of the home or whether there is some chance Rachel and her baby were shot in that bedroom after those checks. Monday, January 23, police find Neil Entwistle's BMW at Logan Airport. The Middlesex County District Attorney holds her first press conference, labeling Entwistle a person of interest.</s>MARTHA COAKLEY, MIDDLESEX COUNTY DISTRICT ATTORNEY: I have not labeled him a suspect. We do not label people suspects. He is somebody we would always be interested in talking to, in that the husband of two people who have been killed. (</s>On camera): January 24, Rachel's family get a phone call here from Neil Entwistle who is staying with his parents in Worksop, England. The British tabloid, "The Sun," reports Entwistle told Rachel's stepfather, quote, "I can't remember how I got to England. Is it true Rachel and Lillian are dead?" (</s>Voice-over): CNN's attempts to reach Entwistle or his attorney have been unsuccessful. January 25, four Massachusetts investigators travel to England to meet with Entwistle. Two days later, Entwistle heads to the U.S. Embassy in London to meet with them. But prosecutors say, under advice from his attorney, he does not answer their questions. January 28, Rachel's obituary runs in the "Boston Globe." Neil Entwistle's name is not included. February 1, Rachel's family lay her and Lillian to rest. Neil Entwistle misses the funeral of his wife and daughter. Today, he remains in England in seclusion. Jason Carroll, CNN, Hopkinton, Massachusetts.</s>COOPER: Well, we talked about this awful case earlier this evening with CNN's Senior Legal Analyst Jeffrey Toobin and Forensic Scientist Lawrence Kobilinsky of the John Jay College of Criminal Justice.</s>COOPER: There's no way they can get him back from England?</s>JEFFREY TOOBIN, CNN SENIOR LEGAL ANALYST: Not unless they charge him with a crime. A grand jury subpoena won't do it. They actually have to charge him with a crime and begin this process known as extradition. It can be a very long process, but it is ultimately likely to be successful, but it can only be done if he's charged first.</s>COOPER: Why not say he's a suspect? Why is the district attorney there going out of her way, repeatedly to say a person of interest?</s>TOOBIN: You know, this is something that's happened only in recent years. None of these terms have any particular legal significance, person of interest, suspect, they're not clear categories. What prosecutors try to do is avoid a claim down the road that there was some sort of prejudicing of the jury pool. So, basically, they're trying to be as cautious as possible. But, I mean, you'd have to be an idiot, frankly, not to regard the husband as an obvious suspect here. So, the fact that the prosecutor isn't saying it, doesn't mean that in any real sense he isn't one. So, of course, he's a suspect.</s>COOPER: And Larry, you actually have a copy of the death certificate for Rachel.</s>LAWRENCE KOBILINSKY, FORENSIC SCIENTIST: Yes.</s>COOPER: What jumps out at you?</s>KOBILINSKY: Well, clearly, they have no real indication of the time of death. Unfortunately, the longer the postmortem interval, when they find the bodies, they're limited in the ability to narrow down the time of death. So there's a wide range.</s>COOPER: Why does that change? Why if it's 24 hours later or 48 hours, does it matter?</s>KOBILINSKY: It makes a big difference because some of the indicators of time of death disappear very quickly. For example, rigormortis, livermortis or the change -- the cooling of the body over time.</s>COOPER: But can they determine from stomach contents, things like that?</s>KOBILINSKY: Those things are useful when the postmortem interval is short. In other words, they find the bodies soon after death. When you start talking about days passing, you can rely on other kinds of things. For example, the potassium level in the vitreous humer, a certain fluid in the eye. That usually goes up with time. So we can get a good estimate, but it's not a pinpoint estimate.</s>COOPER: What shocked me, though, from what you showed me in this report is that, I mean, she died immediate they say; but that the baby, Lillian Rose, who was shot in the stomach, it took minutes for that baby to die.</s>KOBILINSKY: Indeed. The medical examiner found that the bullet that entered the abdomen penetrated and ruptured the liver, as well as the kidney. The child died of exsanguinations -- blood loss, hemorrhage, and so that takes time.</s>COOPER: Jeffrey, Neil Entwistle has not answered police questions. I mean, it's the smartest thing to do. I mean, if you've seen any cop shows, it's always people talking to the police that ends up tripping them up down the road.</s>TOOBIN: Well, and he has a lot to explain. You know, why he left, why he didn't go back for the funeral. All of those things you could do a lot with if you had answers to them. He's much better off as a suspect, which is what he is, not saying anything at all. So he's getting the right legal advice.</s>COOPER: They did not impound the car immediately. They found the car on Monday, after he had left. But for legal reasons, they just kept an eye on it. Is it possible evidence in there could have disappeared in that time?</s>KOBILINSKY: Well, it's a possibility. We have to know if anybody else had access to the vehicle. That's why the videotapes of the vehicle are quite important. But I think what's even more important is the timing of when he left that vehicle because he could have stayed around at the airport. We are saying we don't know exactly when he took off to Britain. It may have been another flight. We're not sure, but we do know from the videotapes when he left the car. So that kind of narrows down his timing with respect to did he have the capability of committing the crime.</s>COOPER: There is another case of a murdered wife that is getting scrutiny tonight. This one has striking similarities to the movie, "The Fugitive." A doctor, accused of poisoning his wife and now he is on the run. But did she live long enough to convict him from the grave? Plus, why are women more likely to be murdered by their husbands than by total strangers? That and more when 360 continues.
