New York: A key witness in the trial of an Indian-origin student accused of spying on his roommate's homosexual tryst in her testimony before a US court said she was "sad and overwhelmed" after learning that her fellow freshman might have committed suicide.
Molly Wei, 19, took the stand on the third day of the trial on Tuesday against Dharun Ravi, who faces 15 criminal counts, including bias intimidation and invasion of privacy for spying on his roommate Tyler Clementi.
Clementi had jumped to his death from a bridge here in September 2010, days after Ravi saw him kissing another man in his dorm room through a webcam.
Ravi, who turned 20 on Tuesday, has not been charged with Clementi's death and faces 10 years in prison if convicted.
Wei had also faced charges in the case but she reached a plea deal with prosecutors, under which she would have had to testify against Ravi and undertake community service to be freed of the charges.
Wei told a New Jersey court that "police officers told me that they believe Tyler is missing and that he possibly committed suicide and I was feeling very -- I was sad, overwhelmed. I felt very bad if anything had happened. I felt overwhelmed with emotions," she said.
She also testified that she had learnt from her friends that Ravi had told some other people about Clementi's date with another man.
"I was very surprised because my friends brought it up, and I had no idea how they knew, but they said that Dharun had told them... They told me about these Twitter, tweets, that they received on Tuesday about him trying to have a viewing party," said Wei.
Wei also told the jury that she did not make any recordings of Clementi kissing his partner, nor did she post it online.
She said Ravi and she had watched the two kissing for only a few seconds and were both "really shocked" at what they saw. She said they had soon turned the webcam off.
"First of all, it was shocking. It felt wrong. We didn't expect to see that. And now that what we did, it was like we shouldn't have seen it," Wei said. "We didn't want people to know what had happened."

The trial is expected to last 3-4 weeks. Ravi has rejected a plea deal that would have kept him out of jail, saying he did nothing wrong and had never wanted to intimidate Clementi.
Ravi's lawyers and some of his friends who testified in the case say Ravi does not harbour any dislike for gay people.
