There may not be enough evidence to upgrade charges against two Rutgers University students accused of secretly taping another student's gay sexual encounter, Middlesex County Prosecutor Bruce Kaplan said.
Freshman Tyler Clementi's roommate and another student used a webcam to broadcast live images of 18-year-old Clementi during the intimate encounter in his dorm room.
Clementi, a promising violinist, jumped off the George Washington Bridge into the Hudson River three days later.
Rutgers freshmen Dharun Ravi, of Plainsboro, and Molly Wei, of West Windsor, are charged with invasion of privacy.
Kaplan says investigators are looking into whether they can upgrade the charges to a bias crime because Clementi was gay.
Over the weekend, students attended vigils to pay tribute to Clementi. Rutgers President Richard McCormick said the vigil was an opportunity for students and staff to come together and "reaffirm our commitment to the values of civility, dignity, compassion and respect."
The vigil was the latest in a series of remembrances for Clementi at the university that included the establishment of a Facebook group, In Honor of Tyler Clementi.
Clementi's death was one of a string of suicides last month involving teens believed to have been victims of anti-gay bullying.
On Friday, more than 500 people attended a memorial service for Seth Walsh, a 13-year-old central California boy who hanged himself after enduring taunts from classmates about being gay.
