Hanged is a weak transitive verb. In most conventions, yes, it is used exclusively for people. Hung is most often used as a much stronger transitive and often not for people. But there is no hard and fast rule for it.
I use HANGED exclusively as a transitive verb when referring to someone being HANGED, as in an execution or as part of a Cartel narcomensaje.
I use HUNG only for people who have HUNG themselves. Just like a HUNG jury is not a HANGED jury, because the jury can only hang itself, so to with people, as far as my personal reporting conventions are concerned.
And while I appreciate your obnoxious pedantry for its own sake, it has no place here in the Death section, so I will ask you (and all others) to not bog this thread down unnecessarily with grammatical distinctions that remain subject to personal convention.
