Court TV aired it's Forensic Files Invisible Intruder episode which is about Darlie. In it was presented the much discussed 2nd attack theory. Blood evidence was used to show how probable it was. The heavy amount of blood at the end of the knife shows someone bled onto it while holding it in a downward direction. Someone who was bleeding. Darlie was bleeding and it was Darlie's blood. Her blood was there in a pattern not indicative of having used it on someone, but of someone bleeding, holding it. She had already cut herself when she held the knife downwards. All she says is she picked up the knife off of the kitchen floor and put in on the counter. She would have had to stand there and hold it to bleed that heavily onto it. And there would have been large drops of blood on the floor there. An outline of the knife in blood(hers?) was found near Damon and there was evidence of her blood near him as well. She never mentioned taking the knife into the family room or over to Damon after she picked it up and put it on the counter. Conclusion: there is scientific evidence for the 2nd attack theory, very strong evidence. So again, the 2nd attack theory was not born on this forum by some crazed poster and believed blindly by millions who cannot think on their own.
