Hydrogen Sulfide Gas Exposure Confirmed as Deadly Cause

Now, officials have confirmed what truly caused the death of these six workers.

In a report from Denver 7 News, these men all died as a result of "hydrogen sulfide gas exposure."

This sort of gas is often found naturally in manure pits and can lead to almost instant death in high quantities, especially in confined spaces, experts say.

Our hearts go out to the families and loved ones of these six men.
