A是检方法医专家,说血渍91和床垫血渍高度相似,出现在犯罪现场正常,出现在谢家不寻常。到底有多不寻常,他也不知道:
Q: Can I just ask you to clarify that. Are you saying that the weaker parts of the profile in item 550 were the ones that were missing from item 616?
A: I'm saying ‑ I'm saying that the alleles that were not present in the sample from the mattress could have been not present because they were diluted out; in other words, a weaker sample, the weaker alleles may not be visible.
A Your Honour, as I've probably said a number of times, what we've got here is something unusual. How do you explain something unusual that doesn't fit within a box, a nice confined box? That's what we've got here. We've got a mixture that was found in a garage that, if it had been found at the murder scene, nobody would have cared about because it looked like it came from the murder scene. Now, we've got something in the garage that, if it doesn't come from the murder scene, it matches by chance.*
Now, the difficulty is trying to equate that chance. I've done it by showing that there is a similarity between the proportions of the different alleles at one scene to the mattress ‑ sorry, the garage to the mattress.
Does it show something? In my opinion it does show something. To what level I would go? I don't know, your Honour.
