Please, sneakypete, never go into law enforcement!
Your posts have demonstrated that you hold women and girls in deep contempt. Thus, it is likely that on a subconscious level, or perhaps not subconscious, you would have the attitude, "she got what was coming to her."
Also, you, and a few others have demonstrated a remarkable ability to overlook obvious leads and discrepencies in a criminal investigation. So what if there were people in the house around the time of the kidnapping...what could they have to do with anything?????
The bar friends, the swingers, the sexual addicts are all the good and nice guys...you would probably go after the monogamous family up the street and harrass them. Your posts have indicated that it's the monogamous men and women that you do not trust and have contempt for.
I know that California is an extremely liberal state, but in many, many other states, if a child is hurt or killed during the course of parental pursuits...such as waking up and wandering into a crack party, and being thrown against the wall...the parents are as liable as the "guest" who threw the child.
This advise is a MUCH better fit on you. You are the one ready to convict somebody for murdering a child because you don't approve of their lifestyle.
