More than 150 people gathered on the campus of Southern Illinois University in Carbondale Monday night to hold a vigil for a missing student from Northwest suburban Morton Grove.
Pravin Varughese, 19, was last seen leaving a party on campus last Wednesday at 11pm.
Cell phone records show he called a friend in Chicago less than two hours later and then made a post on Twitter that suggested he may have been in a fight.
He never returned to a townhouse he shares with a cousin and friend.
Carbondale Police have used helicopters and search dogs, but have not found a trace of Varughese.
His family is offering a $15,000 dollar reward for information about his disappearance.
