This makes me wonder if the perpetrator isn’t very tech-savvy. Did he/she really think that the doorbell camera stores all of the data IN THE DOORBELL CAMERA? I would think that most people would at least have an idea that data is stored elsewhere (i.e. “in the Cloud”) and can be accessed remotely.
I know there are many different types of cameras and that each type probably has different “plan levels”, but to take the physical doorbell camera seems to point to someone who is unaware of current technology. It also makes me feel like this wasn’t well-planned, so could it be personal, impulsive and/or drug-fueled, etc?
My opinion on this would change if evidence shows that the doorbell camera was removed BEFORE the person entered the home. It would be very interesting to see what the last images were that were captured by the camera. Did it show someone trying to conceal their appearance and/or obstruct the camera’s view as they removed it? If so, then this would lead me to believe that this person quite likely entered the home with the intent to harm Nancy and remove her from her home BEFORE they ever entered the home.
