Even in the scenario in which the chain of events began as an accident rather than stalking-and-seizing: if Mickey did not die of her injuries and if she is indeed dead, it would seem most likely that he killed her, likely in circumstances that involved some degree of premeditation (even if only a few minutes or seconds). Even holding her captive if she required medical attention to save her life might qualify for first degree -- of that, I'm not certain, but I wouldn't be surprised.
On a different but related topic: One thing that is worrying me, given BSL's injuries: What if Mickey fought hard enough to actually escape from him -- say, he had taken her to his house and she escaped from any bonds or other methods to contain her and attacked him, then fled, say into woods or fields, but was too injured to then make her way to safety, food, etc. This is one reason I am glad to hear there is searching going on in the area of his residence. Even for those who don't think it likely he would have "disposed" of her that close -- she could still be near there.
