Around 4:30 p.m. Sunday evening, Canfield family practice nurse practitioner Elizabeth Zinni was getting in line for Cedar Point's tallest and fastest coaster, Top Thrill Dragster. That's when she walked into the scene of a woman in her mid-40s, screaming in pain after an unidentified metal object fell from the coaster on it's way back down, piercing her skull.

"It's not something I expected to happen on a day when I was at the park with my family," Zinni told 21 News. "Obviously it's not something this woman expected."

"We see a crowd of people storming out of the line," Zinni described. "I set aside the title of mom and sister and I go into medicine mode."

Zinni rushed to the woman's side and started assisting other nurses who were in line by holding pressure on her wound and comforting the family.

Zinni looked at the woman's head and saw cerebral material coming from her skull. She said she continued to apply pressure to the wound with other nurses until park medical officials arrived. 

"There was no question that the woman needed help," Zinni said. "I tried to do everything that I could until they got there. I'm listening to her screaming and we're just trying to stabilize her head and neck. This woman suffered a severe brain injury- it was severe."

The woman was taken to a local hospital where they told Zinni the woman was intubated and moving Sunday night. Zinni told 21 News she was grateful that she was in the right place at the right time.

"I worked alongside my father and he always taught me, it's the Good Samaritan act," Zinni said. "If you're at a place and you see something happen, you go and help."

As of Monday evening, the woman's condition is unknown.
