The amount of light coming in Travis' bathroom windows at that time of day doesn't make much sense either, my sweet friend.Nor does a man who was utterly through with the lying wench yet drop his drawers the moment she walks through the door (or sneaks up on him while sleeping). Without Melendez' report, we don't know what he did with the camera and memory stick, unfortunately.
If Naps was shut in the office or downstairs bathroom he likely wouldn't have heard anything happening upstairs. All the days Travis was in his shower and the roommates going about their business, no one noticed Naps acting unusually, scratching at T's door, whining, nothing of note, apparently.
Poor Napoleon. TA's roommates seemed oblivious enough, caught up enough in their own lives, that it's quite possible, IMO, Napoleon tried for days to "tell" them, to get their help, but they just didn't notice or follow up. Flores has said both roomies felt tormented for a very long time about the little clues they missed that could have led to finding Travis earlier. Maybe Napoleon's behavior was one of those clues.
About the light in that window. Southern exposure at 5:20pm, in June, Arizona. There's actually a way to calculate how direct the sun would be at that exact time, but the math involved is way over my head, cubed.
We also don't know from the copy of the photo we've seen whether or not the light is natural sunlight or inside lighting, if even an artifact of the memory card recovery process.
More in response about Travis in a bit....nothing you haven't heard before, though, sweet sister -friend.
