Clementi's lawyer said the family is cooperating with the ongoing criminal investigation into Ravi and Wei's alleged actions.
"The case is being investigated by the Rutgers University Police Department.

"The case is also being investigated by the Office of the Vice President for Student Affairs under the code of student conduct."

One of Tyler's friends, Courtney Ayukawa, posted to the group's wall, "I will always remember everything from our preschool's Halloween party to your amazing musical talents. When you picked up the violin and began to play, it was as if everything just paused until you put it down again. We will never forget you Tyler. May you rest in peace."
