I've followed this case for at least 10 years but there are details I've either forgotten or am somewhat fuzzy about. For one, does anyone remember hearing about whether or not LE searched the vacant condo's? Maybe the actual crime scene was in one of those. Even if LE did search the others I wonder how detailed such searches might have been. IOW, if nothing stands out then forensics is not called in.
This entire crime might have taken less than 30-45 minutes between abduction and her murder if it occurs on site. Then if more than one is involved, at least one person removes the body, say, rolled up in carpet, to a van to an offsite location while the other follows in her car. After the body, clothing, briefcase, purse, etc., are hidden, one drops off the car and the other returns to the condos to clean the scene. Her brother, Logan, may have actually seen or even spoken to a killer.
I really don't believe they have to look much farther than the complex to find the guilty party. I do find one conflicting set of information from LE. They identified the workers and tried to verify whereabouts. Yet they didn't speak to Chino until two years later because they couldn't find him?
