LOS ANGELES (CBSLA.com) — A graduate student was found dead at a USC dorm, but authorities say they don’t suspect foul play.

A cleaning crew found the decomposing body Thursday inside a dorm at Seaver Residence Hall. He was identified as Jacob Kelley, a first-year master’s student.

Kelley was last seen by a neighbor a little more than a week ago, KNX 1070 NEWSRADIO reported. It’s not clear how he died, and there were no signs of a struggle or trauma.

“At this time, it’s being investigated as a possible natural death, but we’ll have further once the autopsy is done,” Los Angeles County Coroner’s Ed Winter said.
