This article revisits a very painful event for many physicists, especially here in the US. It involves the murder-suicide of 6 people, including the shooter, back in 1991 at the University of Iowa.
This nightmare has been used as the inspiration for a fictional account of the event in a movie titled "Dark Matter" and won a prize at the recent Sundance Film Festival. Interestingly enough, the film, while ending in the bloody massacre, is described as more about the process of student-mentor in a physics graduate program. Brian Greene has described it as doing a "... really good job of capturing the atmosphere of a research lab".
I would love to see this movie if I didn't know about the story and how it will end. I think it would be just too painful to see such tragedy, at least for me.
