Mom dies on Indiana rollercoaster, here's what a medical expert says was to blame.

The sheer force of an amusement park ride led to a mom’s death, according to a corner in Indiana.

Dawn R. Jankovic, 47, of Ohio, visted the Holiday World & Splashin’ Safari in Indiana in early June. According to a statement from the park, she arrived at the end of the rollercoaster unresponsive.

EMS arrived with three minutes and gave her first aid, according to the park. She was taken to the hospital, where she was pronounced dead.

The park stated it did a full inspection of the coaster and determined the ride operated as it intended.

Holiday World closed the ride for the rest of the evening out of respect for Jankovic’s family.

“Holiday World & Splashin’ Safari officials ask for your thoughts and prayers for the Guest and her family, as well as for Team Members who were onsite,” officials said in a statement at the time.

This week, the Dubois County Coroner office listed three causes of death for Jankovic after completing an autopsy. They were exsanguination, avulsion on the right internal thoracic artery and amusement park rollercoaster, according to the Indianapolis Star.

County Coroner Katie Schuck explained to the newspaper the normal force of the coaster caused the tear in the artery. She stressed the ride had nothing to do with her death other than the force.

Jankovic’s 17-year-old son, Gunnar, created a GoFundMe page after his mom’s death to help pay for the funeral service. It has raised more than $12,000 to date.

“RIP mom you will be missed by your family members, the coaster community, and me, your son,” he wrote.
