New Smyrna Beach, Fla. ? Lake County Sheriff Chris Daniels Sr. was killed Saturday night at New Smyrna Speedway while taking part in a school-bus race to raise money for charity.

Daniels was celebrating his 47th birthday by competing with other area sheriffs in the fifth annual Battle of the Badges, a fundraiser for the Florida Sheriffs Youth Ranches.

Daniels is thought to have died when his bus spun out of control during the 15-lap bus race.

Lake County Jail Operations Chief Gary Borders was in the stands when Daniels was thrown from the bus. He would not discuss the details of the accident but said that “a lot” of sheriff’s office employees were watching.

“It’s devastating and unbelievable,” Borders said.
