A fifth friend has come forward claiming he was present at the Kansas City Chiefs watch party that resulted in three men freezing to death in their pal’s backyard — and has revealed new details about the trio’s final hours.

The fifth person, who has not been named publicly, had joined the group — which included David Harrington, 37, Ricky Johnson, 38, and Clayton McGeeney, 36 — at Jordan Willis’ Kansas City rental on Jan. 7 to watch their hometown team play their last regular season game, attorney John Picerno told FOX 4.

The man told the outlet that when he left the home, Willis and his other three friends were still awake.

The man also stressed that he was not the last person to see Harrington, Johnson and McGeeney alive before they froze to death in Willis’ yard and went unnoticed for two days.

The fifth individual had arrived at the house at about 7 p.m. and left around midnight, his attorney, Andrew Talge, said.

When his client left, the four other men were up watching “Jeopardy!” — indicating that the three victims were still alive in the early hours of Monday, Talge added.

Talge’s version of events contradicts Picerno’s statement, which insisted that Willis saw his four friends out at the end of the night, then went to sleep on his couch. 

Picerno also said several times that Willis — who allegedly slept on his couch for the next two days, unaware that his three friends were frozen in the backyard — only received messages via Facebook Messenger, and did not get texts or calls, FOX 4 noted.

According to Talge, however, his client received a text from McGeeney’s fiancée and from Johnson’s mother, both asking about their loved ones.

Their concerns prompted Talge’s client to text Willis and Johnson, but he did not receive a reply, the lawyer alleged.

Picerno declined to comment on the discrepancy, FOX4 said.

Talge also did not immediately respond to The Post’s request for comment.

Harrington, Johnson and McGeeney’s bodies were not found until Jan. 9, when McGeeney’s fiancée requested a welfare check.

In an interview with NewsNation last week, Picerno said Willis left his home sporadically on Jan. 8 and 9 — only to backtrack on Monday and say that Willis had only been in and out of his bedroom.

Three Kansas City Chiefs fans were found frozen to death in the backyard of their friend’s home on Jan. 9, where they had gathered to watch a football game.

The bodies of David Harrington, 37, Ricky Johnson, 38, and Clayton McGeeney, 36, had possibly been there for two days.

Jordan Willis, the man renting the home, insisted he had “no knowledge” of the fate of his friends.

Willis’ lawyer said the man was “asleep on the couch” for two days while his friends’ loved ones frantically tried to contact him.

“This case is 100% NOT being investigated as a homicide,” Kansas City police Capt. Jake Becchina told Fox News Digital.

Here’s more of The Post’s coverage of the tragedy in Kansas City:

• Kansas City Chiefs fan found dead did not use drugs, was ‘murdered,’ longtime girlfriend says
• House where Kansas City Chiefs fans partied has large windows facing yard where 3 froze to death
• 5th Kansas City Chiefs fan at party where 3 friends were later found frozen to death ID’d: report
• Parents of Chiefs fan found frozen to death alongside 2 friends in yard think trio was drugged, ‘dragged’ outside by scientist pal: ‘He concocted something’
• Drugs a possibility in grisly Kansas City Chiefs fans’ freezing deaths outside home, doctor says

“What I meant to say on NewsNation is that he left — he was sleeping, and he left his bedroom sporadically,” he said, according to FOX 4.

Willis moved out of the home less than a week after the bodies were found, his lawyer added.

The Kansas City Police Department is reportedly still waiting for autopsy and toxicology results — though Capt. Jake Becchina told Fox News Digital that the incident “is 100% NOT being investigated as a homicide.”
