A Lansing, Michigan-based fan passed away yesterday morning, succumbing to a medical emergency on the grounds of Electric Forest at 9:30 AM. The Rothbury, MI event welcomed 45,000 people, and saw performances from bands like The String Cheese Incident, STS9, Greensky Bluegrass and more.

Authorities are still investigating the cause of death with an autopsy, to rule out any potential foul play. Oceana County officers continue to investigate the situation.

While this is the fourth death that has occurred on site since 2012, there is no indicator as to whether this emergency could have been prevented. Our hearts go out to this young man’s family and friends at this difficult time.

Electric Forest has issued the following statement:

On Monday morning, after the festival had ended and campers were leaving the festival site, event medical personnel and Michigan State Police Troopers responded to an alert regarding a medical emergency. As result, a man was transported to a local hospital and we were deeply saddened to later learn that, unfortunately, he had passed away.

While the cause of this tragedy has not yet been determined, this has deeply affected everyone involved with the event. Our heartfelt sympathy goes out to his family and friends.
