Veteran comedy showrunner Alan Kirschenbaum died last night from apparent suicide. He was 51. Kirschenbaum most recently co-created and executive produced with Ajay Sahgal the upcoming midseason CBS comedy series Friend Me. I hear he recently left the show for unknown reasons. Kirschenbaum and Sahgal scored in May when their Friend Me was one of only two CBS comedy pilots to land series pickups.
