KANSAS CITY, Mo. (AP) — It could take four to six weeks before authorities can determine how a man died after an altercation in the parking lot of Arrowhead Stadium during Kansas City's game against Denver, police said Monday.
The man was identified as Kyle A. Vanwinkle, 30, of Smithville. An examination of Vanwinkle's body did not show obvious signs of trauma, Kansas City police spokesman Darin Snapp said in an emailed statement.
Snapp said a man who owned a Jeep and his son returned to the vehicle during Sunday's game and found a man "who did not belong" inside, which led to a fight between the owner and Vanwinkle.
Police responded to a disturbance call in Lot A at Truman Sports Complex, where Arrowhead Stadium is located, and found Vanwinkle on the ground unconscious. Three people were taken into custody Sunday evening, but all were released Monday afternoon with no charges filed.
Snapp said investigators are awaiting autopsy and toxicology reports before deciding whether Vanwinkle's death was the result of a crime.
"We don't know if the person had a health condition, had a heart attack. We don't know," Snapp said Sunday. "We're going to investigate this as a homicide until we hear differently. Right now it's a suspicious death but we are going to investigate it as a homicide."
It wasn't clear whether the men knew each other, or whether the Jeep owner had been in the stadium or was outside tailgating with other fans. Arrowhead has a no re-entry policy, meaning anyone who left the closely contested game would not have been allowed to come back inside.
