I just read the latest report from the Idaho Statesman. Here's what's been released so far:

The rancher was shot dead and a deputy slightly injured.
The rancher's wife's condition from her heart attack has been upgraded from critical to serious.
No info on the car's occupants has been released other than that they were flown to a trauma center.
It's unknown who killed the bull.
It's unknown how the argument started or how it escalated.
It's unknown who brandished a weapon or shot first.
We have 12 pages of posts condemning everyone and anyone based on only the above information.
