Yegads, that's disturbing. :-( I'm really sorry to hear, and I hope they show up again soon. (Um, I'm kinda assuming I fall into the category of 'not suspected,' but for what it's worth, t'wasn't me...)

I've had a lot of fun at the parties that you've thrown, and I hope that your confidence in humanity gets restored by whatever bozo did that soon. It sucks to have lingering questions about friends and acquaintances... *sigh*
