We're not saying who *cough* Jonah Hiller in 3F *cough* but someone defiled the pool.
Whoever committed this atrocious act of butt cleaning has apparently never experienced the exquisite pleasure of expelling a slender turd from inside the cool aquatic confines of a public pool. Why bother pooping on the deck or diving board, when pooping inside the pool itself is so much more efficient? Get your pooping and your butt cleaning done all at once! Here's hoping the folks at Redditor CyrusKain's apartment complex figured out exactly what happened here using security camera footage.
