is it possible the remains were so thoroughly destroyed by flame that they can't tell who it was yet?
Agree it may take time as the poor soul was burned. However, there are two things are disconcerting: First, people know and are not saying. Secondly, the coroner is not releasing any statement that they are attempting to positively id the body. It makes legal and human decency sense to get it right and to take the time necessary to do so. Having some inside information prior to the crash on the cornoner's office and their resources (or lack there of) I was informed it may take months or up to a year for them to id the persons.
Think about it, if you are in the situation where you are waiting for an answer, knowing that this positive identification of bodies is slow at the county, how would you feel? I hope you never experience it because it prolongs the hurt.
