A Sioux City teenager died and three others were hospitalized after police say they became ill while smoking a synthetic drug. Officer Jeremy McClure of the Sioux City Police Department says emergency responders were initially called late Thursday night to War Eagle Park to check on a person who was sick.

McCloud and the three other victims, between the ages of 16 and18, were found together in a car shortly after 11 p.m.

The names of the other three victims are not being released, but McClure said they are all students at Sioux City West High School. It remains unclear exactly what substances were being used by the four teens.

For now, no charges have been filed in the case.
