A 39-year-old man suffered a heart attack at Lollapalooza and died, Chicago police say.
He was taken to Northwestern by a Chicago Fire Department ambulance at about 1pm, department spokesman Kevin MacGregor said, according to the Trib.
The man was initially attended to by private paramedics at the scene. It was the department's first and only ambulance call from Grant Park all day.
While the Cook County medical examiner's office has not been notified of any deaths related to the festival, Chicago Police News Affairs Officer Kevin Kilmer say the man died about 2:30pm. Police are investigating.
