Thank you so much for the house photo! I don't like to google 'TA + any kind of photo'. When I did that once I got some gruesome photos as a result that made me physically sick.
I strongly agree with entering via the office window. Possibly through the doggie door, too.
No way she opened the garage door with the key pad. My kitchen is right above my garage and when somebody opens the door to drive in I can hear the door opening clearly even with other noises in the kitchen. I recently installed a quiet motor type and I can still hear the door opening from upstairs.
I have same experience with garage door. And again, looking at the layout of his house, there is zero percent chance Napoleon wouldn't have heard the garage door opening, then the inside door opening, then her coming through the laundry room into that narrow short hallway.
Either the sliding door, office window, or not at all until further into the day, sneaking in when TA is out bike-riding (if he went). If not through the office window, though, when would she have taken the screen off? Isn't that typically done from outside?
After watching the video of his neighborhood, I'm really baffled where it is she parked, IF she arrived and parked before Zach and Enrique left that day. Couldn't have been in the garage or in the driveway, and I doubt she parked in front of his house.
