PITTSBURGH — Pittsburghers expected to have to dodge ice-covered sidewalks and piles of snow along Commonwealth Place. Two weeks after a winter storm dropped several inches in the region, the city was still struggling to clean up its remnants.

But it was the poop, piles and piles of it, littering the sidewalks in front of the luxury “Apartments at River View” building that was the bigger challenge. It wasn’t your average animal, or perhaps human, excrement coming from one mere defiler.
