True, but that isn't what I am doing here. We can all find out at the trial. Many have made the assumption that JITB is what the DD was. That is probably correct, but I don't recall seeing it as a known fact anywhere. DD didn't say so, LE didn't say so. The correct answer to "Do we know what Xana ordered" is that we not only don't know what food item(s) she ordered, but we can't even say for a fact that it was JITB. We only assume based on what we have seen and putting pieces together. (that is 'we' as in the generic 'we')Xana's eating habits can be easily asked of the surviving roommates.
But supposed she ordered DD JITB the day before, the bag was still there because they reused paper bags in the house for other things and the DD for that night was actually from somewhere else and THAT packaging was already in an evidence bag somewhere? That fits what we have seen, too.
At the moment, I, personally, can't say for absolute sure that JITB is what was ordered that night, though I do lean that way. MOO, of course.
