We can't be sure of anything. A lot of people have assumed that the first shots were directed at him, but the shots that the neighbors heard could just as well have been from when they shot the door to gain entrance. (I've seen both "kicked in" and "shot in". I wonder if the shots were at the locks, and then the door was kicked? Maybe.) So once inside, it might be that both JC and DC were still alive, as would make more sense if they were looking for or asking about something specific. Then later, maybe 20 minutes later, both are killed. Order doesn't really matter. But location might. Was JC trying to make a break to get help, which is why he was by the door?
Of course, none of this explains why Jayme was taken. And that's the odd thing. Generally these types of home invasions don't result in the abduction of a child, although I know there are exceptions.
