Jury questioning begins Wednesday in the trial of Dharun Ravi, the former Rutgers student accused of spying on his roommate, Tyler Clementi, with a webcam.
Clementi committed suicide by jumping off the George Washington Bridge in September of 2010.
Ravi now faces 15 charges of invasion of privacy, witness and evidence tampering, as well as "bias intimidation" -- a hate crime punishable by 10 years in prison.
Tyler Clementi's brother, James Clementi, recently published a letter to his brother in Out magazine. On "CBS This Morning, "48 Hours Mystery" correspondent Erin Moriarty pointed out the letter doesn't mention Ravi's name, even as many still blame Ravi for Clementi's death.
The letter says, in part, "I wish it didn't take you dying for your soul to know peace. I wish you could read the hundreds of letters we got, hear the thousands who rallied and marched for you, know the millions who followed your story on the 6 o'clock news. You were never alone; it just felt like it."
In the letter, James Clementi reveals that he told his brother he was homosexual -- and that Tyler told him the same.
The case against Ravi in Clementi's death is expected to focus on Ravi's emails, tweets, and text message. Prosecutors will try to prove Ravi harassed Clementi because he believed his college roommate was gay.
According to court records made public, even before he met Clementi, Ravi chatted to a friend "F*** MY LIFE/He's gay."
Later, Ravi twice focused his computer camera at Clementi's bed when Clementi had a man in the room, the second time posting on the social media site Twitter, "Yes, It's happening again."
Two days after he discovered that Ravi had spied on him, Clementi took a train to New York City. At 8:42 p.m. that evening, he left this message on Facebook: "jumping off the gw bridge sorry."
Clementi's body was discovered in the Hudson River a week later.
The tragic outcome, according to law professor Marc Poirier, may be a reason Ravi is facing unusually harsh charges. He told CBS News, "Even though the suicide is technically not anywhere in the charges, when you talk to people on the street, you go on the web, it's still often perceived as Ravi did something that caused Clementi to kill himself."
Ironically, the digital record may also help Ravi's defense. His attorneys are expected to use Clementi's own online postings to show that he did not feel intimidated. Clementi wrote to a friend after he realized he'd been spied on, "doesn't seem soooo bad lol."
The night Clementi took the train to New York, Ravi sent him a text that read in part, "I've known you were gay and I have no problem with it....I don't want your freshman year to be ruined because of a petty misunderstanding."
Clementi most likely never got a chance to read it.
Social media evidence in this case, "Moriarty said, is a "sign of the times."
"We're going to see this more and more," she said. "And it's not just to prove intent, which is just for basic charges, but what's worrisome is, prosecutors are using this electronic evidence to actually bring more serious charges. Dharun Ravi would have just been charged with invasion of privacy but because of his tweets and texts they charge him with bias intimidation, which is a hate crime, which covers a much harsher sentence."
The Yeardley Love case is another example of the tech trail being used by the prosecution, Moriarty said. "(George Huguely, the boyfriend accused of Love's murder has a defense that says) he didn't mean to do it, and he might have been facing manslaughter charges, but he sent that, I think it was an email, two days later saying, 'I should have killed you.' Boom. First-degree charges."
The relationship between Clementi and Ravi was "so sad," Moriarty said, because they spoke about each other to other people more than they spoke to each other directly.
She said, "You keep wondering could this whole thing have been avoided if they had talked out their differences."
