A horrific 13-car crash at Daytona International Speedway on Saturday injured at least 28 fans, including at least two critically, when the front of a race car broke away and an engine, tire and other debris flew into and over a safety fence and into the grandstands.

Fourteen fans were taken to three area hospitals, Speedway President Joie Chitwood III said at a 7 p.m. news conference. Fourteen other fans were treated at the Speedway’s Infield Care Center, Chitwood said.

“There was carnage and debris and people running everywhere,” said Larry Spencer, whose 15-year-old brother Derrick’s face was cut by a piece of flying debris. “It was a crazy scene.”

Spencer said he took his brother to the hospital, where he received three stitches, because there were “a lot of people in our section that were certainly in a lot worse shape.”

It was unclear how many patients, like the Spencers, might have driven themselves or family members to hospitals. After the crash, rescue workers were seen in at least three sections of the stands.

At Halifax Health Medical Center, seven patients were taken to the emergency room in Daytona Beach, two of those — an adult and a minor — with critical injuries, said hospital spokesman Byron Cogdell. Six patients were taken to the medical center’s hospital in Port Orange. All of the Halifax patients were listed in stable condition, Cogdell said.

Another patient was taken to Florida Hospital Memorial Medical Center, said spokeswoman Lindsay Rew. That patient’s condition was not available.

“First and foremost our thoughts and prayers are with our race fans,” Chitwood said during the news conference after the crash.
