Tyler Clementi, the Rutgers University freshman who in 2010 jumped to his death from the George Washington bridge, suspected his roommate had spied on him via webcam during a sexual encounter, according to testimony in the trial of Dharun Ravi.

Ravi, 20, is charged with multiple counts in Clementi’s death, including invasion of privacy and bias intimidation. Gary Charydczak, a computer expert for Middlesex County prosecutors, testified Tuesday that Clementi visited Ravi’s Twitter account dozens of times after he had an intimate encounter with another man, the New Jersey Star-Ledger reports.

Two days after Clementi’s encounter, Ravi tweeted, “Roommate asked for the room till midnight. I went into molly’s room and turned on my webcam. I saw him making out with a dude. Yay.”

Clementi saved screenshots of two tweets from Ravi and quickly applied for a room change. He committed suicide hours later.
