ROTHBURY, Mich. (WZZM) -- Michigan State Police are awaiting autopsy results on a 21-year-old man who died at the Electric Forest music festival in Oceana County.

Joseph Norris, 21, of Portage suffered an unknown medical emergency around 12:40 p.m. Thursday and died. Norris had been hired by an outside contractor at the Electric Forest Festival.

This is not the first death for the festival. Last year, a Connecticut man died at the Electric Forest Festival from drug use. And in 2008 there were two drug-related deaths at the Rothbury Festival.

The Electric Forest Festival runs through Sunday.
