Family and friends are searching for a missing Southern Illinois University student from Morton Grove.
19-year-old Pravin Varughese was last seen Wednesday night at a party on the Carbondale campus.
Phone records show he called a friend in Chicago almost two hours later.
That friend said it sounded like Varughese might have been running or arguing with someone. Varughese also posted a message on Twitter suggesting he may have been in a fight.
The family is offering a $5,000 reward for information leading to his whereabouts.
Police have not said if they suspect foul play.
