Police spokesman Darin Snapp says an examination of Vanwinkle's body did not show obvious signs of trauma. He says it could be four to six weeks before the cause of death is determined.
Officers responded at 5:20 p.m. Sunday to an altercation in the parking lot and found Vanwinkle unconscious on the ground. Snapp says a Jeep owner and his son returned to the vehicle during the Chiefs game against Denver and found Vanwinkle inside, leading to a fight.
He says Vanwinkle was taken to a hospital, where he was declared dead.
Three people taken into custody for questioning were released Monday with no charges filed.
