A boy was killed in a July Fourth parade on Thursday in Edmond, Oklahoma, according to CNN.
The boy somehow fell or jumped out of the martial-arts-decorated float and was run over by the trailer, said CNN.
Edmond Police Officer James Hamm told the Associated Press the incident took place during the LibertyFest event in Edmond, which is in central Oklahoma.
"The driver, obviously unknowing what was going on, drove forward and ran over the child," Hamm told the AP, describing the incident as "a freak, unfortunate accident."
No other information was immediately available.
