Lower Merion police were able to identify a man accused of defecating in the stairwell of a Bryn Mawr public library after Facebook users raised a stink. On Monday afternoon, the department posted surveillance video on its Facebook page, asking the public to help find the man shown on the video, who was accused of twice defecating in the stairwell of Ludington Library in Bryn Mawr on Dec. 17. Hours later, they posted that the suspect had been identified. "The Investigations Unit would like to thank our FB friends for your partnership," police posted. "A tentative identification has been made in the case of criminal mischief at Ludington Library." Police did not indicate whether the suspect was charged, but the surveillance video was later removed from the page. A message left with police was not immediately returned. Underneath the department's post indicating a suspect had been identified, some residents were quick to post pithy remarks. Hugh Ehrenberg, for instance, posted: "Will there be an attempt at a ballistic match?" Barbara Hayman added: "Were they any skidmarks? Resident Michele Cohen, meanwhile, expressed concern for the suspect's mental well-being. "I am glad they identified him," Cohen wrote. "We should have some sympathy. He clearly has a problem." Police responded: "Michele, you are sincere and correct. Our investigators will work through all issues present and proceed with empathy and integrity." Police added later: "Grateful also for the good humor of our FB friends."
