ANDERSON, Ind. (AP)—A safety crew member killed by a race car at Anderson Speedway entered the track too soon on a caution and had his back to oncoming traffic, track officials said.

The coroner said 49-year-old Roy Hiatt died from blunt-force injuries to the head and chest.

It was not clear why Hiatt went onto the track when he did during Saturday’s Pay Less Little 500. Track owner Rick Dawson said Hiatt was trying to clean up an oil spill. Dawson added that driver Tyler Underwood did not see Hiatt in time to avoid hitting him and witnesses shouted to get Hiatt’s attention.

Dawson said it was the first death on the track since he bought it about 12 years ago.
