Overzealous zookeeper, Friedrich Riesfeldt, (Paderborn , Germany) fed his constipated elephant, Stefan, 22 doses of animal laxative and more  than a bushel of berries, figs and prunes before the plugged-up  pachyderm finally let it fly, and suffocated the keeper under 200  pounds of poop!
Investigators say ill-fated Friedrich (46), was  attempting to give the ailing elephant an olive oil enema when the relieved beast unloaded on him. 
- "The sheer force of the elephant's unexpected defecation knocked Mr. Riesfeldt to the ground where he struck his head on a rock and lay unconscious as the elephant continued to evacuate his bowels on top of him" said flabbergasted Paderborn police detective Erik Dern.
With no one there to help him,  he lay under all that dung for at least an hour before a watchman came along, and during that time he suffocated.
It seems to be just one of  those freak accidents that proves; "Shit happens"
