Does anyone know who this information about BM being at firefighting training originally came from? I thought family had said he was in Denver on a work-related trip, but has anyone in the family specified that it was firefighting related? Is the media just running with an assumption that work = firefighting although he's just a volunteer and his day job is in landscaping?
I'd be surprised if he was in Denver specifically for firefighting training. Every major training/conference event I know of has been postponed or cancelled. Traveling out of one's county is so strongly discouraged right now that most local governments have cancelled work travel for all employees for the forseeable future.
Even before COVID, it would be uncommon for a volunteer FFer from this part of the state to ever need to travel that far for training. There's typically plenty of opportunities much closer. Colorado Mountain College has a very robust firefighter training program and most of these departments are capable of hosting nearly all training in-house.
