An Ohio woman is dead after a ride on one of the world’s tallest wooden roller coasters.

47-year-old Dawn R. Jankovic of Brunswick, Ohio boarded The Voyage roller coaster early Saturday evening. When the train arrived back at the station, she was found unresponsive, according to a Holiday World Facebook post.

Holiday World EMTs arrived three minutes later and immediately began to render first aid. Jankovic was transported via ambulance to a nearby hospital where she was pronounced dead, according to the Dubois County Coroner. An autopsy was performed with results pending.

An inspection of the roller coaster was performed, and it was determined  the ride was fully operational.
