I sense we are getting into the realm of alternative motives.
An Asian gang targets prostitutes, kills them and harvests their organs to be sold on the black market.
If you could connect the victims to a clinic/doctor/lab, where the preliminary tissue testing could be done without the victim being aware, it becomes plausible.
That way the gang would have a data base, and when orders came in they could have the victim pre-determined. It sounds good for a basis of a novel.
But again truth can be stranger than fiction. MP could fit into this scenario well, except initially his profile was too high, as I believe these gangs are very secretive.
Again I ask has anybody seen, heard or spoken to MP in the last six months?
Where is he?
