The reason for the shocking deaths of three Kansas Chiefs fans found frozen to death outside a HIV scientist’s home may never be known, officials have admitted.

The bodies of David Harrington, Ricky Johnson and Clayton McGeeney were found in the backyard of their friend Jordan Willis’s home in Kansas City, Missouri, back in January.

While toxicology reports released to the distressed families showed all three had cocaine, THC and fentanyl in their system, officials have not revealed a cause of death for the men.

But this week a medical examiner told FOX 4 that their investigation was finalized on January 31, even though they never released a cause or manner of death.

‘Our office finalized cause and manners of death for all three of the decedents,’ said Kelsie Gwartney with the Kansas’ forensic medical office.

‘All three cases are under suppression status and not open records available for release at this time.’

The relatives told FOX 4 after the latest news that they feel their questions are being ignored by authorities and they fear charges will never come.

‘My nephew died a tragic death along with two of his friends and nobody is being held accountable,’ said McGeeney’s uncle Jim McGeeney.

The grieving uncle added: ‘If a plane crashes what are they going to do, get the black box, they can find out what happened, but with this, three dead men, they don’t do anything, it appears they don’t do anything and if they are, let us know.’

Police have only said the investigation into the deaths remains open, but have added they are not probing the case as a homicide.

Officials had also said they were awaiting reports from the medical examiner, which the families now know were finalized six months ago.

Willis, a HIV scientist, moved out of his home within days of police knocking on his door to question him about the bodies, fearing retaliation

For two days after the sports watch party, the families of the victims say they visited Willis’ home, called him and sent him Facebook messages asking where they were

Harrington, 37, Ricky Johnson, 38, and Clayton McGeeney, 36, were found dead and frozen in Willis’ backyard in Kansas City, Missouri, on January 9.

After the men’s deaths, Willis checked into rehab, a friend claimed.

Willis, a HIV scientist, moved out of his home within days of police knocking on his door to question him about the bodies, fearing retaliation.

For two days after the sports watch party, the families of the victims say they visited Willis’ home, called him and sent him Facebook messages asking where they were. He did not respond.

Eventually, the fiancée of one of the men broke into the house through the basement and found the first body in the backyard. She then called police, who arrived to find Willis in his underwear, holding a wine glass.

Willis claimed to not have left his home for two days and slept with noise-cancelling headphones that blocked the sound of his friends’ family frantic knocking.
