"Items of clothing and a hair combing sample from the defendant Sonia Sahota were submitted to this laboratory. In my opinion the amount of glass which was found on these items is greater than would be expected if the defendant were seated in the passenger seat only throughout the incident. This is mainly due to the position of the impact being on the far right of the windscreen of the vehicle. Therefore the glass evidence gathered from the clothing is more consistent with the defendant moving into the driver's seat of the vehicle and thus coming into contact with glass particles on the seat post the impact."
"Q. .... Will the windscreen actually disintegrate into fragment inside the car? A. Yes, it will. Q. And in which direction will those fragments go on impact like this? A. It's slightly dependent upon the position of the impact and possibly on the direction of the impact on to the window. If something is to hit it at an extreme angle it would stand to reason that any glass that breaks would pass back in the same direction into the vehicle. MR RECORDER BAKER: You are doing an illustration. You passed your hands in front of your chest. If there is an oblique impact on to the .... A-frame for instance, just to the side of the A-frame, is it possible that if it was a very oblique approach the glass could be shot across the front? A. Across rather than directly backwards into, yes. MR RECORDER BAKER: Yes, if it is a head-on impact, something coming into the windscreen from the front, is it more likely then to pass straight back in the course of the -- A. More likely to go straight back, yes. MR RECORDER BAKER: So the distribution of glass bears some relationship to the angle of approach of the object? A. That's correct, yes. MR RECORDER BAKER: I hope that is clear."
"MR EVANS: .... What if Sonia Sahota had been sitting in the passenger seat at the time of the accident and moved over to the driver's seat after the accident? How would that fit in with what you found in your scientific examination? A. It's possible that the amount of glass recovered from that clothing could be accounted for by being in the passenger seat at the time of the impact and then moving to the driver's seat. However, the only addition I would make to that is that wouldn't account for the lack of glass on the clothing of the person who is in the driver's seat. MR RECORDER BAKER: I just want to be clear. If Sonia Sahota had moved across, that exercise could attract glass fragments to her clothing? A. That's correct. MR RECORDER BAKER: And what, the fragments she would have picked up had she been in the passenger seat at the time would depend on the angle of inclination of the object hitting the windscreen? A. That's correct. MR RECORDER BAKER: About which you cannot help us? A. Unfortunately not, no."
"Q. Right. Now, it is a common-sense proposition, is it not, that if the force of the impact is at an angle, then the glass leaving the inside surface of the windscreen is going to be going off at the same angle? That is right, is it not? A. I would say that's common sense. Q. And really the amount of glass that somebody sitting inside the car receives on their body or their clothing depends whether they are in the firing line? A. That's also correct, yes. Q. And in this case it is clear, is it not, that there was an oblique impact with the windscreen? You accept that? A. I couldn't tell from the photographs the angle of impact. Q. I see. MR RECORDER BAKER: You may not have heard the evidence. The evidence is that this little boy ran into the front wing of the car and then was propelled, sadly, in the air, and came into contact with the, just beside the A-frame of the car, coming in from the side of the car. Now, that is the evidence before the jury. Does that help you at all? A. Yes. Obviously, again, touching the fact that it would be common sense, if there was an angle to the impact it would spread the glass across the vehicle inside. MR QUIRKE: It is a bit like, I suppose, somebody shooting a shotgun through the window, is it not? It is going to be in that line? A. Yes, there is a straight line impact through the window, yes."
"MR QUIRKE: You know I am reading it to you. You said in December 2004, 'The glass gathered from the clothing', her clothing, 'is more consistent with her moving into the driver's seat of the vehicle and thus coming into contact with glass particles on the seat after the impact'. That is your opinion, is it not? A. It's my opinion based on the fact that the amount of glass recovered, as I have said, was higher than I would expect. Q. Because you put that into a witness statement, did you not? A. That's correct, yes. Q. And because of the way the glass is gathered we cannot say, you cannot say, whether some of the glass may have come from the backside of her jeans, or the backs of the legs of her jeans, as she climbed over the seat? A. That's correct. It's not possible to tell -- Q. We cannot say that, can we? A. -- the specific origin of where on the garment the glass has originated. Q. And that is why you are really driven to accept the possibility that the glass is from that climbing-over motion? Is that not right? A. Driven to accept that as a possibility, yes. Q. Well, more consistent with her having done that? A. That was my statement, yes. Q. And was that your opinion? A. Yes."
"Given the other findings in the case, whilst it's possible that the glass found in Sonia Sahota's clothing is consistent with the movement from the passenger's to the driver's seat, I would still, regardless of any physical activity, expect to find glass on the clothing of the person who was sat in the driver's seat at the time of the impact. Q. And the absence of glass on that person's clothing leads you to what conclusion? A. In my opinion they were not positioned in the driver's seat at the time of impact."
"The attitude and the position of cleaning marks to the collision vehicle's bonnet do not suggest any great momentum on behalf of the pedestrian across the latitude of the Vectra"
"Q. Mr Booker, you have been asked about the distribution of the glass within the motor car assuming that there was a side impact to the windscreen. I am just going to deal with this proposition, if I may. It may be the case that the boy who struck this windscreen was first of all thrown up into the air and came down on the windscreen without at that point going at any appreciable velocity across the car. If that is right, where would you expect the distribution of glass fragment in the car to be, mainly and overall? A. If the impact is literally straight back down on to the windscreen, on to an angled windscreen, common sense, as we said earlier, would be that any angled impact would pass the glass in a direction back across the vehicle. Any direct impact would spread it straight back from the point of impact, in that case towards the driver's seat. Q. Would you still expect there to be some glass fragments across on the passenger side of the car? A. From that type of impact? Q. Yes. A. Yes, but very little."
"I will take great care when I come to this part of the evidence to make sure that the jury have it well in mind that there is no evidence before them other than that of Mrs Chambers .... that the child went up in the air and landed down and I will link that evidence with Mr Booker, who said what he would then expect that to lead to in the passage of glass [namely more glass in the driver's seat]."
"He explained to you that the angle of impact could have a bearing on the direction of travel of the glass inside the car. And he said if the angle was an oblique angle, it would tend to push the glass more across the car. And he said the smaller the glass fragments the further the glass was likely to travel and you are dealing here with microscopic glass fragments, which had to be seen under a microscope and he said a moderately powerful one, but that is the sort of fragment you are dealing with. Now there is very little evidence on the details of the impact in this case. You know that the windscreen is broken or cracked just by the A-frame, to the right of the driver's position in front of the car. The evidence you may think you have heard from the witnesses is that Dexter collided with the offside of the Vectra and was thrown up in the air. That seems to be a picture that a number of witnesses paint. The evidence of Mrs Chambers was that having hit the side of the car he was thrown up in the air and came down from above, onto the windscreen and the defence rely on that as indicating that there was more likelihood of the glass going straight back in the car, towards the driver, not across towards the passenger side."
"His conclusion was, from his analysis, that there was good evidence to place Sonia Sahota in the driver's seat at the time of the impact. He agreed that relative retentive properties of the front passenger's clothing and the movement of glass within the car, if it was at an oblique angle, which of course the defence say there is no evidence it was at all, could help to explain the fragments in the clothing and hair of the front passenger. So he accepted that. They said if the passenger moved across the driver's seat, this is the shuffling across as described by a few of the witnesses, there would be the glass that may well be there from the impact, there would be the glass that she would pick up from the centre console and there would be glass that she would pick up from the driver's seat, having got into it. And so he said there were three potential sources of glass, if that had happened. It is for you to say what happened. And he put it in this way. He said, 'I would entertain that the picking up of the fragments in that way is a distinct possibility'. It was put to him that in his witness statement he had said slightly more than that, saying it was consistent with that having happened, but his evidence before you is that he would entertain it as a distinct possibility that one could pick up those fragments by shuffling across with what may already be there, what you would pick up on the console and what you would pick up on the seat behind. He said this, towards the end of his evidence, given the other findings that he had made in the case, 'I would have expected to find glass fragments in the clothing of the driver'. If Dexter's head came down into the windscreen from above, in a direct line, he would expect the glass fragments to pass into the driver's side as opposed to across. He said physical exertion after the glass has got into the clothing or the hair for that matter, would lead to the shedding of fragments. He said the more vigorous and strenuous the exercise the more fragments you would expect to shed. And he was asked by the prosecution, you remember, if you had to run a long way through the streets being chased by people, would that be something where you would lose fragments and he said, 'Well you would but I cannot tell you how many you would lose [as] I do not know how many there were in the first place'."
