More details are being released about the death of a 19-year-old SIU Carbondale student.  An attorney for Pravin Varughese's family says they have proof that he was beaten before he died.  They say an independent autopsy determined he suffered from blunt force trauma and he had defensive wounds on his arms.  That contradicts the official coroner's report, which ruled Varughese had frozen to death on a cold February night.  He was found in a wooded area five days after he vanished from an off-campus party.  Witnesses said he'd gotten into a vehicle with someone he didn't know very well.  The family has filed a lawsuit against the man who was driving that vehicle.  And, they're claiming the city of Carbondale and the chief of police were negligent in the way they handled the case.
