An Andersonville man collapsed just moments after riding one of Six Flags Great America’s rollercoasters on Saturday. He later died at Advocate Condell Medical Center in Libertyville, being ruled as a ‘natural death.’

The 50-year-old Scott Barnes, complained about being sick after leaving the rollercoaster named Superman: Ultimate flight. Soon after, he fell to the ground on the ramp that riders use to exit the ride. Barnes was attending the Great America’s yearly LGBT event “Out in the Park” with friends.

The park’s communications manager, Tess Claussen, told the Tribune that the man collapsed Saturday evening in the walkway exiting the ride. She further added that there are warning signs posted near all ride locations warning people with medical conditions to be aware.

The rollercoaster, which hurdles riders through twists and loops at over 50 miles per hour was shut down for a time during the incident. People experience ‘extreme’ forces when on the 115-foot tall steel coaster while flying face down and parallel to the track. The ride was introduced in 2003 and designed by the Swiss firm Bolliger & Mabillard.

Barnes, an Indiana native, worked as a digital content specialist with the American Medical Association. His family will hold a visitation on Friday from 4 p.m.-8 p.m. at Geisen-Carlisle Funeral Home, 613 Washington in Michigan City, IN. His funeral will be held on Saturday.

Area friends will hold a memorial for Barnes next Wednesday, Sept. 20 from 7 p.m.-9 p.m. at Elixir Lounge 1509 W. Balmoral.
