The first train of thought is to recognize the perp chose the--perfect night--in consideration of all identities fatique level. Bone tired!

The second consideration is that the Police are looking for post Christmas burglars with vehicles. No vehicle?

The third consideration is IF the female child vagina penetration was an act to misdirect the investigation as to perp identity. To chase the #1 hated demon of the sadistic peodophile. Perp's control.

Christmas night was the perfect night and a professionally trained decision IMO as would be the vagina deception. Either way, the vagina penetration and murder is not lessoned in any measure as too, the perp's sadistic peodophile--murderous--nature.

Why Christmas night of all nights? Fatique of all!

The--ransom note--was the unprofessional declaration of information, identifier and so evidence. Why so important to perp?
