I'm stumped too, Cathryn. I know an attorney up here who does mediation/arbitration whose name is Chris Lavdiotis and for some reason when I saw your "Lazmayo," that's what I thought of. But the firm he's with is Lombardi, Loper & Conant, which sounds nothing like "Carcasus." So, obviously, I'm not much help ;P Sorry!! Good luck.
I just went back and listened to the tape. He mentioned the firm name twice. It sounded like KAR/KAEUS/US (strong emphasis on middle syllable) both times, and Lazmayo and Lazamayo, respectively.
I am resigned to calling the attorney on Monday, but I'm still taking input. Thanks to all who are working to help.
