The three Kansas City Chiefs fans found frozen in their friend's backyard died of fentanyl and cocaine toxicity, as new details about their bizarre deaths unravel.

Kansas City police confirmed there was no foul play in the deaths of three friends found frozen in their buddy’s backyard over a year ago — putting to rest boundless theories that dogged the bizarre tragedy.

Jordan Willis and Ivory Carson have been charged with manslaughter 14 months after three men — Ricky Johnson, David Harrington and Clayton McGeeney — were found dead on Jan. 9. Their remains were found outside of Willis' home two days after watching a Chiefs game.

In a statement released by the department, it was found that the deaths of Johnson Jr, Harrington and McGeeney involved no foul play. The friends had officially died of 'fentanyl and cocaine toxicity', after several bags of potentially-lethal drugs were found inside Willis' home.

Two men have been charged in the deaths of three Kansas City Chiefs fans whose bodies were found in a backyard two days after they gathered to watch a game.

The charges come more than a year after Ricky Johnson, Clayton McGeeney and David Harrington were found dead outside of a home in Missouri.

The medical examiner in Kansas City determined that Clayton McGeeney, 36; Ricky Johnson, 38; and David Harrington, 37, died from a combined toxicity of fentanyl and cocaine.
