because it would be difficult for Damon to still be alive if she attacked him the 2nd time while Darin was still upstairs. Even if we lengthen the amount of time the ME suspects Damon could have lived after the fatal wound, it's a pretty tight squeeze. I doubt the ME is far off the mark. We can hear Darin on the tape and we know when Damon died, not the time, but as far as who was there, etc.When is Darin first heard on the tape..like at about a mintue or something? I'm too lazy to look it up right now. Then the first PO gets there at about 3:35 mins, I think, we can hear him on the tape. Then we can hear when Walling arrives, they do a cursury search and then let the ME's in. Damon is still alive and dies what about a minute after what's-his-face gets to him, right? I just think it's too long.
Damon took his last breathe as soon as Kolbye rolled him over- which was the first thing he did when he got to Damon (apart from briefly checking his back). The ME estimation was that Damon could have lived 8-9mins with the wounds he sustained. That means that from the final wound there is a countdown of say 8 minutes. Even if the paramedics did not get into the house until +6.30mins from the 911 call (which I think is being a bit generous anyway) that still leaves a generous 1.5mins within the ME estimation. And since Damon died right when Kolbye went over to him that 1.5min is easily achieved. It means that Darlie must have called 911 very quickly after Damon had been stabbed the second time... but if she had already wounded herself and then seen he was still alive and attacked him again then there would be no doubt she wanted paramedics there ASAP to tend to her own wounds.
The timeline is tight but quite realistic- surely more realisitic than imagining that either Darlie or Darin stabbed Damon during the call. It would have meant making sure that nothing was heard which would incriminate them and would have involved VERY skilled playacting by Darlie as she was talking to the operator. She wouldn't have been able to give anything away, whether that he getting Darin to stab Damon, doing it herself or responding to Darin's attack on him. It's hard enough to talk on the phone when you are distracted by TV or something let alone by stabbing your own child.
And if they DID stab him whilst she was on the phone then why did they leave him still alive when Waddell arrived? If the point was to kill him then why didn't they keep going until he was dead? Instead they left him alive. Now, if Darlie had attacked him a second time right before she called 911 then there would have been no opportunity for her to have done so again when she sees he is alive since Darin was downstairs quick smart.
