oh completely
Most of that trafficking stuff is urban myth. Human trafficking does exist of course, but no one is stealing 3 year old kids to order from holiday resorts.
Out of interest, this is the precise theory of the case developed by Mark Harrison for the PJ in 2007
Most likely the child was killed swiftly and concealed locally.
Abduction cases frequently have up to 3 crime scenes. The abduction scene, then an hidden crime scene where the abductor takes the victim - this is a place the abductor controls, and then the dumping ground where the body is either dumped or concealed.
IMO the case will never be resolved unless the dumping ground is located.
