Toxicology results show a missing Southern Illinois University student had no alcohol or drugs in his system when he was found dead in Carbondale in February, his family says.
The body of Pravin Varughese, a 19-year-old sophomore from Morton Grove, was discovered Feb. 18 in a wooded area in the 1400 block of East Main Street in the Southern Illinois town.
Police said Varughese was last seen a week earlier at a party where he accepted a ride home from someone authorities believe he met there. The two apparently had a fight, police said, and Varughese got out of the vehicle and went into the wooded area.
Police said in February they believe low temperatures and difficult terrain contributed to Varughese not being able to find his way out of the woods.
An autopsy later revealed he died of hypothermia, and authorities said they don't suspect foul play.
Varughese's mother told NBC5 sister station WPSD the toxicology report proves her son's integrity. His sister said she doesn't accept police reports that there was no foul play and will continue looking for answers.
The family has hired a private investigator, WPSD reports.
