Who do you think killed Carmen (Y&R)?

honestly i think it was brad or mr kim. they are both very guilty acting. Mr kim said that she would no longer be a problem and brad was lerking after he thought carmen overheard him and victoria. The only other person I think it could be, would be jenna- i think that is what her name is, Kevins girlfriend. She is up to something and I am not sure what yet. I cant wait to find out.
