Forensic investigators identify 23 MH17 crash victims using fingerprints and dental records
176 "mostly complete" bodies were found.
Two of the victims were identified using fingerprints while dental records were used to help identify the other 21.
Article says DNA will be used to identify the majority of victims.
As mentioned earlier in this thread, visual ID by relatives is not reliable so leaving bodies in situ to aide investigators does not compromise identification at a later time.
