*Snipped*. It is a whole lot more likely then the coroner clipping the nails without informing the DNA expert. The coroner reports everything he does. There is no evidence that he clipped the nails and threw the clippings away. It doesn't work like that. It just shows how easily everyone involved in this case is attacked. I think probably Meredith cut her own nails. Of course, there is no proof of anyone else cutting Meredith's nails that night, but there is plenty of proof of a cleaning and staging taking place. If I think of that and the picture of the scratch on Knox's neck then it wouldn't surprise me at all that she decided to cut the nails. That is JMO.
When you put it like that, it makes sense.
