Just because Wes believes the parents (father) could be involved does not make it true. Just because some otherd might believe it is the boyfriend does not make it true.
I personally do not feel LE bungled the investigation. I, like BDE, believe they have looked into more of the parent's statements and checked them out than we have been told. Why would they tell us everything they have/know?
I agree chi-mama, this is not helpful. We've heard it several times, discussed the possibilities. Discussed the differences in heritage backgrounds that may exist, etc. it has not been dismissed, but we either need new info to keep picking at this or look for more possibilities that are logical. Constantly deflecting to only the father being a "suspect" seems to have a basis in something other than just wanting a crime solved, IMO.
Gunning her down on a run (where he could have been seen or even identified) would make no sense for her father .... there would have been many other "better" opportunities to do so, if he had intended to get rid of his own daughter. I do not believe he did.
