For a few days there was speculation Mingo County, W.Va., Sheriff Eugene Crum was murdered recently because of his crackdown on illegal drug activity.
But the county's prosecuting attorney said there is no reason to believe that. Now, it appears Crum was the victim of a mentally deranged killer.
A 37-year-old man, Tennis Melvin Maynard, has been charged with walking up to Crum's cruiser while the sheriff was sitting in it and shooting him to death. Maynard's father said his son, wounded by a deputy who chased him down, is mentally unstable as a result of a workplace accident.
If Crum was merely the victim of a deranged killer who happened to choose him as a victim, his will be far from the only life lost for that reason during the past year or so.
Such violence raises the question of how to prevent unstable people from obtaining firearms, or even whether that is possible.
In Congress, a "universal background check" rule for gun purchases is being discussed. It has wide support, including some from gun-rights advocates.
Sheriff Crum's death may be more evidence of the need for such a system to prevent at least some deranged people from buying guns.
