The Thai PoPo may be following up on a lead that Carradine used his King Fu skills and strength to leave a clue behind as to who his assailant(s)/kinky sex partner(s) may have been.
There are anonymous rumors circulating that particles from one of Carradine's toe nails were found embedded into the wall, in the same spot where what appears to be the initials "DWB" were crudely etched into the closet wall.
Authorities have yet to determine if DWB is possibly a person's initials or an acronym for some sort of kinky cult, but they are asking the public for any help, tips, or bribes that they can provide.
