I don't think so...
I just looked it up and "remains" means "a corpse".
IF I hear Rather talk one more time of the JFK funeral, and the comparisons to Reagan I am going to kick in the TV!
Aaarrrggghhhhh!
The first definition talks about "what is left over" - yes, definition 2 is a corpse but.. to me it implies physical pieces missing. I don't recall ever hearing it apply to a whole person. Maybe it's just my memory.
