Defense rests case in Rutgers roommate-spying trial Former Rutgers student Dharun Ravi faces a 15-count indictment in connection with his roommate's suicide. Dharun Ravi, 20, is charged with 15 counts after his roommate's suicide Prosecutors allege that Ravi spied on and intimidated his gay roommate, Tyler Clementi The defense says Ravi had a secret webcam in his room to monitor his personal belongings Ravi declines to testify on his behalf, setting up closing arguments and jury deliberations (CNN) -- Defense attorneys rested their case Monday in the trial of a former Rutgers student accused of spying on and intimidating his gay roommate, who later killed himself by jumping off New York's George Washington Bridge. The defense rested without the defendant, Dharun Ravi, testifying on his own behalf. With the prosecution declining to offer a rebuttal and the jury heading home for the day, the next step Tuesday will be closing arguments from both sides. After those, the jury will weigh Ravi's guilt on 15 counts including bias intimidation, invasion of privacy, tampering with physical evidence, witness tampering and hindering apprehension or prosecution. The case caught national attention in fall 2010, after the suicide of Ravi's roommate Tyler Clementi. His death stirred discussion about bullying, with President Barack Obama releasing a videotaped message less than a month later condemning such treatment. Ravi and Molly Wei -- who admitted joining Ravi to watch a surreptitious webcam encounter involving Clementi and another man in September 2010 -- were later charged in the wake of Clementi's death. Facing two counts of invasion of privacy, Wei reached a plea deal in May 2011 that required her to testify against her friend and former high school classmate, as well as to complete a three-year program on cyberbullying and do 300 hours of community service. But Ravi, now 20, turned down a plea deal offered by Middlesex County prosecutors that would have let him avoid jail time in exchange for undergoing counseling, doing 600 hours of community service and disposing of any information that could identify the man who appeared in the web video with Clementi. If convicted on all counts after the more than two-week trial, Ravi could be sentenced 10 years in prison. During the prosecution's phase of the trial, the man that Clementi was intimate with told jurors that he had noticed a web camera aimed at Clementi's bed. The 32-year-old man, identified only as M.B., testified that he first met Clementi on an internet social networking site for gay men and that they eventually met in the student's dorm room three times. Wei testified that she watched a sexual liaison involving M.B. and Clementi with Ravi, who had secretly set up the webcam in his and Clementi's room. Ravi's lawyer Steven Altman has argued that his client had switched on the webcam to monitor his personal items because he did not trust his roommate's visitor, not necessarily because Clementi was gay. In Twitter messages from that day, Ravi wrote that he'd gone into a friend's room, "turned on my webcam" and saw his roommate "making out with a dude." Michelle Huang testified that, two days later, Ravi sent out another message telling his Twitter followers -- of which Huang was one -- "I dare you to videochat me between the hours of 9:30 and 12. Huang, Ravi's friend from high school, said that Ravi explained that day in a text to her that he'd set his "computer to alert (him) if anyone is in (the room) when I'm not there." Ravi said that he was "creeped out" by the September 19 romantic encounter between Clementi and the other man. "Mad people are going to do it," he texted her, using slang to suggest large numbers planned to watch. During her testimony, Wei said she was surprised to learn that Ravi had talked about and taken to Twitter to hype the webcam scheme and to essentially advertise that others could watch an upcoming liaison. They told me about these Twitter, tweets, that they received on Tuesday about him trying to have a viewing party," she said. Later in the trial, two family friends of Ravi testified that they'd never heard the defendant make derogatory remarks about gay people. They also said, however, that they never had occasion to discuss the subject with him.
