“Ravi was tired of walking into his dorm room and catching his roommate being intimate with guys”
The article accompanying this story on another thread stated that the deceased asked for use of the room until midnight.
From that article-
“Roommate asked for the room till midnight,” read the post from Dharun Ravi, 18. “I went into Molly’s room and turned on my webcam. I saw him making out with a dude. Yay.”
