NEW BRUNSWICK, N.J. (AP) - The parents of a Rutgers University student who killed himself after authorities said his roommate used a webcam to spy on his tryst with a man intend to sue the university.

The attorney for Tyler Clementi's parents filed notice Dec. 18.

Attorney Stephen DeFeo says it appears Rutgers failed to implement or enforce policies that would have prevented or deterred such acts.

Rutgers spokesman E.J. Miranda told The Home News Tribune of East Brunswick the university sympathizes with the family. But Miranda says Rutgers is not responsible for the freshman's death.

Clementi's roommate, Dharun Ravi, and fellow freshman Molly Wei are charged with invasion of privacy and have withdrawn from Rutgers.

Clementi jumped to his death off the George Washington Bridge in September.
