In child abduction cases the child is usually killed within 1 hour of the abduction. In 74% of the cases, though, the child is killed within 3 hours of the abduction. In 99% of all cases the child is killed within the first 7 days after the abduction. 22% of children are still alive at the time they are reported missing and 42% are killed before they are even reported missing.

Hope that helps.
