As clean-up continues at west Michigan's Rothbury Festival, officials have announced a man and a woman died at the event. 

Troopers say the two people were in separate groups and had separate medical emergencies on Sunday.  Autopsies have been completed but no cause of death was found.  A toxicology report will be read in three to four weeks.

The identity of both victims will not be released.

Thousands were in the tiny village of Rothbury near Lake Michigan for the festival which included performances by The Dave Matthews Band and Snoop Dogg.
