NEW YORK - A body found in the Hudson River off New York City has been identified as that of a Rutgers student whose sexual encounter was allegedly secretly streamed online.

The New York City medical examiner's office confirmed today that 18-year-old Tyler Clementi committed suicide. A spokeswoman for the medical examiner's office says he drowned and had impact injuries on his torso.A family lawyer had already said Clementi jumped off the George Washington Bridge, but officials at the time had not identified the body.

Clementi's roommate at New Jersey's Rutgers University and another freshman have been charged with invading the teen's privacy. Prosecutors say they used a webcam to surreptitiously transmit live images of Clementi having sex with a man Sept. 19.

When asked about the case at a news conference, Gov. Chris Christie (R-N.J.) called it an "unspeakable tragedy," and warned those involved in the filming of the video that they would have to "bear the responsibility" of what happened for the rest of their lives.
