NEW BRUNSWICK, N.J. (AP) - A former Rutgers University student convicted of using a webcam to spy on his gay roommate is poised to start serving his 30-day jail sentence.
    
Dharun Ravi (dah-ROON' RAH'-vee) is scheduled to turn himself in today at the Middlesex County Jail in New Jersey. The 20-year-old was convicted in March of bias intimidation, invasion of privacy and other charges.
    
Ravi could have remained free while prosecutors appeal his sentence.
    
But during a hearing Wednesday, he agreed to waive his protection from double jeopardy. He is now not allowed to argue that he's already served his time if prosecutors prevail on their appeal and he receives a longer sentence.
    
Ravi's roommate, Tyler Clementi, committed suicide in September 2010, days after Ravi used a webcam to see him kissing another man.
