Ken Rosenberg

Ken Rosenberg is a decertified lawyer who went mental and was last scene at a mental health center. In the year 1992 (Grand Theft Auto: San Andreas), he was used by the Leone Mafia Family to run the casino (Caligula's Palace) that they co-own with two other Mafia families. After that, he is never heard from again. However, during the video game Grand Theft Auto: Vice City, he was on a downward slope when he met Tommy Vercetti and eventually came to briefly become one of the most important men in the city, before Tommy fired him as lawyer and he lost his career.

The missions that Carl Johnson does for Mr. Rosenberg not only help him keep his job at the casino, it also helps him stay alive until CJ can liberate him from his situation and back to a "safe, legal job" with a "boring commute." After being a part of killing Johnny Sindacco, Carl tells Ken to "play it dumb" until he can figure out a way to fake his death so that Mr. Ronsenberg can finally leave Las Venturas.
