Michael Zhuang, a friend of Ravi's for six years, describes the suspect as someone into computer programming and video games.
Zhuang told ABC News he believes Ravi was excited to go to Rutgers and believes the media portrayals of Ravi as possibly homophobic or a serious prankster are not true.
"I'm in shock, I didn't expect this to happen and I am just speechless. He's normally very nice and I don't think that this is a representation of him," said Zhuang.
"He's very very open minded and he, like if it had been a girl in the room it wouldn't have been any different," he said.
Jim O'Neill, the public information officer for prosecutor's office, declined to comment on the case.
Both Wei and Ravi surrendered to police. Wei has been released on her own recognizance and Ravi posted $25,000 bail.
Under New Jersey's invasion-of-privacy statutes, it is a fourth degree crime to collect or view images depicting nudity or sexual contact involving another individual without that person's consent, and it is a third degree crime to transmit or distribute such images. The penalty for conviction of a third degree offense can include a prison term of up to five years.
Lawyers for both Wei and Ravi did not respond to messages left by ABC News.
