The unknown suspect has been defecating on slides at Ypsilanti’s Prospect Park at such a frequent rate that police have installed a hidden camera. Advertisement The head of the Friends of Prospect Park, council Member Pete Murdock, called the purposeful pooping “weird and deliberate.” “We most definitely need to get this under control before school (recess) and park season starts,” Murdock told the Ann Arbor News. "It’s hard to deal with because it’s so unbelievable to begin with. When somebody called me and told me what happened I said 'What? You gotta be kidding me!'" According to Murdock, the deliberate defecator usually strikes at night. “We have a problem in Prospect Park with a miscreant that does not understand the difference between a children’s playground slide and a toilet,” Ypsilanti Police Chief Tony DeGiusti wrote in an email to his staff. “Apparently this extremely misguided individual feels the need to defecate on the slide despite the cold weather. This has been an ongoing problem at this location. Please make frequent checks in the area and record them on your daily log.” Advertisement The Friends of the Prospect Park may stake out the park once the weather warms up. “We need to get him or her and get them the help they need,” Murdock said.
