Mystery deepens over Kansas City men found dead in friend’s frozen backyard

Police hope tests may shed light on deaths of trio who went to watch NFL game at friend's home and died without him knowing

As an attorney for the HIV researcher Jordan Willis tells it, his client hosted four friends at his home on 7 January to watch their home town Kansas City Chiefs win a football game on television, said goodbye to them and went to sleep. Three of those men soon died in the backyard in freezing weather without him even realizing it, and their bodies were found days later - by someone other than Willis.

Now Willis is grappling with public scrutiny and anxiously" awaiting the results of tests aiming to determine what substances may have been in his late friends' blood and whether any played a role in their seemingly mysterious deaths, according to his lawyer.
