Who cares!!? Four suicides, River Phoenix might as well be suicide (anyone who does heroin is an idiot;) so that's five folks who wanted to end it all. Hexum died after doing an idiotic thing, holding up a pistol with blanks and pulling the trigger; it's still gonna hurt folks. Tate and Schaeffer are the only two legitimately tragic deaths on that list.
Onward and upward, life goes on. ob-la-di, ob-la-da.
