Man that is known simply as "Bobby" calls local news station to report a serial pooper. And here is Bobby's story.

Bobby realized someone kept pooping on the side of his apartment. After looking at his security tape he realized it was a young women on her morning run that was leaving behind her mark.

Maybe there is more to this story we don't know. As someone who has dealt with my fair share of crazy women, I would be surprised if they use to date and she was getting back at him. Or maybe she's just marking her territory. Either way I don't think she will do it again after being on the evening news.
