This is a great post and I thought some of the same things when I first became aware of this case after seeing 48 hours when it was first on. Then you realize that whatever her first strike was, gun or a knife to the chest, it was a fatal wound. Maybe not fatal immediately, but within a number of minutes. He just would not die fast enough, so she kept attacking. But I think that Travis was in great pain and shock from that first wound and so could not defend himself as he would have otherwise been able to. He does have defensive wounds to his hands, so he did make some attempt.....
The other thing to keep in mind, is that, aside from this trial, where Travisnis being portrayed as some kind of violent abuser by his murderer, EVERYONE else in his life remembers him as being a gentleman. I believe he had such a strong abhorrence to violence, that even as she was clearly trying to kill him, he only tried to defend himself and just could not bring himself to HURT her. Ultimately that is what allowed her to continue her attack and take his life. Jmo, of course.
