"He never even paused to acknowledge that Tyler was in the room," she said. "He never stopped what he was doing, no greeting, no smile, no recognition, no nothing."
Jane Clementi said that though she initially thought Ravi may have been stressed or busy, she said she realized during trial that that was not the case.
She heard during the trial that Ravi had not reached out to her son on Facebook or via email, but, rather, had used his computer skills to plug Clementi's email address into various computer programs to discover what websites he frequented and to discover that Tyler was gay.
"He never really knew Tyler, not the smart, kind, articulate, humble, funny, talented, caring, thoughtful, generous, trustworthy and dependable person Tyler was," she said. "All he found out was that Tyler was gay."
She called Ravi's actions toward her son "arrogant and mean-spirited."
Clementi's brother, James, told the court, "I watched as Dharun slept through court as if it was not worth" paying attention. "I watched Dharun and his lawyers laugh as if it were a private joke."
Earlier a lawyer for MB read a statement asking for prison time for Ravi because, he said, Ravi has not accepted responsibility for his actions.
"He must serve some type of confinement… To this day he appears to blame me for his conduct," citing Ravi's claim that he spied on his roommate because he feared MB would steal his iPad.
MB said he does not believe, however, that Ravi should be deported.
In recent days, several prominent gay activists have made public pleas for Ravi to not be sent to prison.
The judge began the proceedings today by noting the court had received a box full of petitions seeking a pardon for Ravi.
Some of the petitions were addressed to President Obama, but the judge said the president has no ability to pardon someone for a state crime.
Some of the petitions were addressed to New Jersey Gov. Chris Christie, who would have the authority to pardon someone for a state crime.
