There is a body. There is a funeral. Parents grieve and mourn but in time the anguish eases and they adjust to coping with their loss. Abduction is worse than death because it creates a lifetime of unassuaged anguish, guilt, longing, blame, and a host of feelings that never really ease. Every birthday that passes is an anniversary of renewed pain.
All questions go unanswered.
The sadness of parents who lose their children through abduction stays with them until the end of their lives, with only death bringing a release from the melancholy that has enveloped them. They had lost their child to strangers. They had failed their child who had been stolen from the bosom of its family and deposited with strangers. It had been deprived of its heritage and taken against its parents wishes into a new existence, a new future, and its natural family bonds broken, probably forever. History is bunk.
