During the preliminary investigation it was learned that a 2008 Hyundai was traveling westbound on 4^th Avenue when it failed to negotiate the curve onto 44^th Street and left the roadway and flipped over. There were three male occupants in the car, two of whom suffered critical injuries. They were transported to Unity Point Trinity Hospital in Rock Island and later flown to University of Iowa Hospitals. The third occupant was treated and released suffering only minor injuries.

 The occupants’ identities are not being released at this time. The accident remains under investigation by the Rock Island Police Department’s Traffic Crash Reconstruction Unit.
