I don't believe NP was killed in TB's house, several reasons:
1) the house was released the day the crime scene tape came down
2) having been released as a crime scene for this long there has been no "clean up" ...no Belfor, servicemaster or any other clean up company there(unless of course a neighbor can confirm there was?) One would think if a crime that horrific that the funeral was closed casket there would need to be some kind of clean up of the place the crime took place.
3) the houses are fairly close together and the yards are not very big at all, you would think that at some point the neighbors would have seen or heard something. Screaming, someone carrying an adult body out of the house and putting it in a vehicle, I mean one neighbor has claimed to have seen TB at 4 am. Did that neighbor see them put something the size of an adult human body in the vehicle? Did they see TB because they woke up due to strange noises? Or were they already awake and seen a car and wondered what was going on?
As for the yellow balloons at TB's house those are actually at the house beside her house. It just looks like they are at her house. Maybe a neighbor, if there is one on here would be kind enough to post a picture of TB's house ( time stamped of course) to show there are no balloons or there are balloons on TB's house, seeing as her house has been plastered all over the news and we all know what it looks like, if it was a picture of JUST her house, would that be allowed?
