Hero is CRAI on river WTF!!!

[tarath]

Villian is 16/12/5 over 250 hands. I'm trying to learn to 8 table (I usually do 6) so I didn't have as much of a read on him as I might like, he raised a few of my c-bets but thats it.

This is a massive bet but I just can't imagine what he could possible have that qould check turn and crai river when I looked so weak that its hard to imagine he was counting on me betting river... Thoughts? Anyone care to put him on a range?
