As minimal as the text info is today, I was glad to hear that there was apparently evidence on both CC's arms. The way I remember back in the way-back machine right after this happened, it was reported that he had a scratch on one arm, which he initially told a witness (maybe an EMT?) he didn't remember how he got, but which he later told his father he got while punching a gurney.
Scratches on one arm and red marks on the other. That "gurney" apparently fought back.
Brian, I'm with you in hoping there was recoverable DNA under the victims' nails. But would we have already heard about that? It seems the prosecution put the ME and Baden on the stand early and are now on to motive, so how much more might we hear about the results from the crime scene?
