Law and Order SVU Season 10: Who is returning and who isn't?

Question

Ok, at the end of Season 9, I got the impression that ADA Casey Novak was going to be disbarred for at least a year (does anyone know why they are taking her off the show?), and they are replacing her with Michaela McManus (from One Tree Hill). However, I got the impression that Tutuola (Ice-T) and Lake (Adam Bench) might not be returning either (Tutuola as he was requesting a transfer, and Lake because he had been arrested). Anyone have any news? Best answer gets 10 points!

Answer 1

On April 18, 2008, it was reported by the Hollywood Reporter that Adam Beach was leaving his role after his one season contract had officially expired.

On May 13, 2008, the season finale, both Beach and Neal left the show. It was announced on June 24, 2008 that Michaela McManus would replace Neal as the show's new ADA when it returns for its tenth season.

Ice T is listed in the cast for season 10 so I`m assuming he`ll be back.
