In the many unidentified decedent cases in the world, there are several cases where the individual is eventually identified. Most bodies are provisionally identified within a matter of hours, with the formal identification following a few days, weeks, or months later. This list is for those bodies where that initial provisional identification failed for some reason. The majority of people in the list will be murder victims although it is not exclusive to them.
