A maximum of 48. Multiple shards from the same skull might be involved, for example.
The writing is atrocious.
Agree, in the article it states that 12 people, I believe that was the number, have been identified as victims, and the 10,000 as you say may be parts of bones in which there may be many pieces of the same bone.
------------------------
Yeah, 206 bones in the human body plus fractured pieces. 10K "pieces" equals ~35-40 victims. See: "Yellow Journalism" or "If it bleeds it leads".
