Three Kansas City Chiefs fans found dead in friend's backyard had several substances in body after toxicology report

More details surrounding the mysterious deaths of three Kansas City Chiefs fans has been revealed from family members, it has been reported.

Three men were found dead outside a home in Kansas City, Missouri, on January 9.

David Harrington, 37, Ricky Johnson, 38, and Clayton McGeeney, 36, were last seen alive two days prior after they went over to Jordan Willis’s rented home to watch the Chiefs take on the LA Chargers.

Willis was informed of their death by police despite being at home those two days.

Police initially went to the home after one of the men’s fiancée's requested a welfare check and discovered the bodies.

When informed by police of the bodies being found in the backyard, Willis claimed he had been asleep for nearly two days and did not realize his friends had died.

Each of the bodies were sent away and police hoped a toxicology report would shed more light on their deaths.

Newsnation’s Alex Caprariello took to social media and claimed that a family member had told him about the preliminary findings of the toxicology report.

Writing on X (formerly Twitter), he alleged: “A family member, who asked to remain anonymous, tells me cocaine, fentanyl and THC showed up in the preliminary results. The family source says level 10 fentanyl is enough to kill. The #KansasCity3 were at level 30.”
