We know that after GBC reported his wife missing the Police deemed his residence a
crime scene. This has intrigued me and I went searching for more info. I've posted the link below for those who also don't fully understand the term. So it would seem that a crime scene is not necessarily where a crime was committed but can be in some way related to the crime. (See Secondary Crime Scene below).

What I'm getting at is that Allison may not have met her death in the house but what caused her death was at the house when the Police arrived and noticed certain things. It could well have been the scratch on GBC's face (I personally can't see it in any of the photos of him and I've zoomed in to 400%) but IMO it was one of the cars that piqued the interest of the Police, prompting them to call in the Homicide Squad immediately.
The two cars obviously hold a lot of answers as to what happened to Allison IMO and I found myself looking at pics of both cars more closely, wondering what may have occurred.

Crime scene means the area associated with a suspected crime from/in which physical evidence may be obtained.
This can include structures, rooms, open areas, vehicles and persons.The Police Powers and Responsibilities Act 2000 defines a crime as a primary crime scene or a secondary crime scene.

Primary crime scene is where a crime actually occurred.
Secondary crime scene is in some way related to the crime but is not where the actual crime took place.

Evidence means articles, items or things that can be used to determine the facts associated with a particular matter or to prove or disprove a fact in a court of law.
Physical evidence need not be visible to the naked eye and can include but is not limited to such evidence as clothing, DNA, documents, weapons, fingerprints, footprints, footwear impression which may need to be enhanced in order to be recorded, compared and analysed or any other item located at a crime scene. Importantly any item at a crime scene can potentially be evidence.
Preservation of evidence means deliberate and specific action taken or caused to be taken with the intention of preventing contamination to, damage to, the loss of, or destruction of, any evidence including the recording, storage and maintenance of continuity of such evidence.
