It was a packed courtroom at the Rutgers bias trial against Dharun Ravi. The man who had an intimate encounter with Tyler Clementi in front of a webcam was supposed to testify Thursday but did not.
The privacy-invasion trial of a Rutgers student accused of using a webcam to spy on his roommate kissing another man wrapped for another day Thursday without testimony from the man.
The man, who has been identified only by as M.B., was mentioned often in the first three days of testimony in the trial of Dharun Ravi, 20.
Ravi's roommate, Tyler Clementi, committed suicide in September 2010, days after prosecutors say Ravi briefly watched webcam footage of the encounter with M.B.
The man was expected to testify as early as Thursday, but has not yet taken the stand.
Prosecutors meanwhile began building their case that Ravi tried to cover up his crimes.
Jurors heard testimony Thursday on how a Rutgers official looked at Ravi's Twitter posts after Clementi was reported missing.
Gone was a post that students testified they had seen "daring" people to video-chat with him at a time when Clementi was planning to have a guest in the dorm room.
Clementi killed himself later that day.
Ravi is charged with invasion of privacy, bias intimidation and several counts that allege he tried to cover his tracks.
