House has lost a long standing cast member, with Dr Lawrence Kutner (played by Kal Penn) being killed of in Monday night’s episode.
In Series 5, episode 20, House was curious why Kutner didn’t not show up to work, and sends Foreman and Dr. Hadley to investigate. When they enter his apartment, they find him dead by suicide.
Never one to miss an opportunity, the Fox Network has set up a memorial site for Kutner here. The site includes memorial video, obituary, and an option for fans to leave their own thoughts on Kutner’s demise.
Kutner wasn’t a major character in the show, but did have a recurring role, often delivering as a humorous counterpoint to House.
