Court documents say Xana was on TikTok at 4:12.
Someone was asking how could we know if the timestamps on the neighbor's camera were correct. I believe they are due to the fact that they are the same times that are being stated in court documents for the different events. When they pair the times for the car travel on that camera with the times that car/it's lights appears on other cameras in the neighborhood, they work out. Grey Hughes has a video(s) showing how the neighbor's video camera footage times are accurate by going between the document with all the times from all the neighborhood cameras and footage of him driving that same route.
Here are the exact time stamps from the neighbor's security camera:
4:17:33-4:17:35 voice(s) caught on camera
4:17:40 thud sound
4:17:53 dog starts to bark
4:20:45 headlights of killers car show up on camera followed shortly by the car itself coming within view
--end of voices to thud sound:
5 seconds
--end of thud to the dog starting to bark:
13 seconds
--beginning of dog barking to car headlights coming into view as it starts to speed away (which ----isn't necessarily when the car was started...the problem is, we don't know where he parked. If he parked on the hill to the side there would be several seconds between the car starting and when it turned onto the road in front of the house):
2 min 53 seconds
If the voice sounds came from inside the house, than IMHO the thud had to as well because those two things were only 5 seconds apart--not enough time for BK get from XK's room and out through the slider door to make that thud outside. When DM saw him, she didn't say he was running.
