That still happens from time to time; often the incidents are blamed on Santeria and similar beliefs. Perhaps just the work of jerky kids who want to PLAY at these rituals.
Last year a deceased Connecticut toddler was found by a river in New Jersey, one of several unrelated discoveries in the area. This baby had attracted media attention during her life because she had survived almost 2 years with terminal deformities before dying of pneumonia, IIRC.
The family was not even aware her grave had been opened, because small children's graves are often too shallow and often lack vaults. They ended up having the baby cremated.
Anyway, the reason for the theft was because of the poor little one's "miraculous" long survival--- it seems some cults believe that conferred her with magical powers. Luckily they didn't harm her otherwise.
