In 1995 the most created "cover story" I believe that could ever be Imagine was attempted but turned a town then nation on it toes day and night for a week looking for a body in a river.
A mother had planned to sell her baby to into slavery but had to account for the where about of the baby.
So the mother claimed she paid an illegal alien to baby set he child then had a friend call a fake report of a "mexican" throwing a baby in the river.
The most common and less drama "cover story" is the over 40% of the child's or person's blood at the scene of what becomes labeled "the scene of the crime". An inexperience investigator will testify that the fact over 40% of the victims blood was fount their it is scientifically impossible for the victim to be alive and this will
in almost all cases lead to a legal declaration of the child or person being dead. If blood is drawn from the intended victim of trafficking well advance over a period of time and house in the ripe temperature enough blood could be accumulated from the victim to leave about of blood equal to over 40% of the amount of blood in the victims body. It a person fakes a kidnapping with "witnesses" then the bloody crime scene is fount it will more than likely lead to the victim being declared dead. An intelligent person may assume
a person dead base on the fact over 40% of the person blood was at the scene but the fact would still remain
the victim was still alive. A person may get a conviction in such a case even with out a body but that does not change the fact the victim is still alive.
Human trafficking is a very lucrative crime and as time goes on criminal become more organized and Intelligent. DO NOT be fooled and Just because they call themselves Child protective Services does not mean they protect. Just like the mother who "faked" the baby over the bridge story IS NOT a mother but a preditor.
