Three people were found dead in a camper at a Kansas race track.
McPherson County Sheriff's Department said in a news release Saturday the discovery was made at the Inman Motocross track.
The sheriff's department said it is investigating with help from Inman Police. The preliminary indication is the victims died from carbon monoxide poisoning. The names of the victims have not been released.
Inman Motocross said in a post there had been a "tragedy" and that the Kansas Motocross Championship Series was being postponed.
"Today," the post said, "we hug our loved ones extra tight and say I love you an extra time."
