The death investigation into three football fans found dead outside a friend's Missouri home last month when temperatures dropped below freezing remained ongoing Friday as law enforcement awaited autopsy results, according to information from police and a lawyer close to the case.

Ricky Johnson, 38, David Harrington, 37, and Clayton McGeeney, 36, were found dead Jan. 9 outside a man's house in a Kansas City suburb, the Kansas City Police Department reported in January.

The home is rented by a 38-year-old scientist who lives alone and works remotely for a New York hospital, the man's Kansas City-based lawyer, John Picerno previously told USA TODAY.

USA TODAY is not naming the man who lives in the home because he has not been arrested or charged with a crime.

Although police said foul play is not suspected in their deaths, officials from multiple agencies have been working to determine how the men died.

USA TODAY has requested copies of their autopsy and toxicology reports when they are available for public release. Results can take anywhere from six weeks to months to be completed.

Here is timeline of the men's deaths and what we know so far:
