KK under heavy fire

[Wayfare]

What do you guys think on the flop? I was planning to raise the turn turn all-in as long as MP dropped. I wasn't as worried about SB because I don't think he would fire out a full pot bet with a set on that board. What the hell did UTG+1 have? If he had a set he played it pretty poorly.
