The Mad Pooper is the nickname given to an unidentified woman in Colorado Springs, Colorado, United States, who repeatedly defecated in public while jogging during the summer months of 2017. While she primarily targeted one family's property, she did not use it exclusively, leaving some of her excrement at other sites nearby. Photographs of her were made public, but neither she nor anyone who knows her came forward with further information that might identify her.
Police believed the woman's actions were intentional, since there are several public toilets within a block of the family's house that she could have used. After the case received national media attention, a purported spokesman claimed in a YouTube video that her actions were related to recent medical issues and enjoyed First Amendment protection; however that video turned out to be a hoax. Procter & Gamble offered her a free year's supply of its Charmin brand toilet paper if she turns herself in.
After a burst of news media coverage in mid-September, police reported that there had been no further reports of the woman defecating in public, although she had not been identified. A few commentators speculated about her possible motives. One believed she might suffer from Crohn's disease; another, in Psychology Today, proposed that she was an exhibitionist with poor impulse control taking revenge on the family who had caught her.
