Been hearing this is likely someone who knew her but the timeline with the camera being disconnected does not mean they were in the house at that time because the camera was posted right next to the front door.

2 Scenarios come to mind meaning that they could have been in the house open the door and then took that camera out meaning they took screwdrivers and unscrewed the camera or

They went to the front door from the outside and did the same thing Although you would think that other cameras if there were other cameras that were viewing the front door or the front pathway that they would have seen something or they would have done motion detection.
