Where is he?

Boardwalk Empire. He was 1 of the 2 main characters of the show and there were many plans for his character and the storyline but he was so difficult (came late, always high, belligerent, held up shooting, etc.), that after 2 seasons, the producers couldn't take it anymore. They changed the entire course and plot of the show, it was all prewitten how the show will end and what would happen, but they divurged course just to write him out. It's a shame because writing his character out really destroyed a great show, and many left after he was written out. I don't blame the producers but I stayed only 1 season before leaving too. Recently, I rewatched the entire show and it really became a different show after season 3.
