An Illinois Institute of Technology student mysteriously turned up dead in a storage room of his fraternity house yesterday, after being considered missing for 8 days, the Chicago Tribune reports. Benjamin Collen’s death has been ruled an accident—the 19-year-old sophomore died of asphyxia after inhaling carbon dioxide from a canister. But it’s unclear how his body went unnoticed for so long.
The body was found by a fraternity brother; police won’t say whether they’d searched the building. Collen had been a member of the fraternity since his freshman year, but no longer lived in the house; he was kicked out a few weeks ago, a friend said. Police say no investigation is underway, because there is no evidence of wrongdoing.
