Cathy Budde says she was first alerted to the woman she’s dubbed “The Mad Pooper” by her children, who caught the jogger in the act weeks ago. Budde tells KKTV-TV the woman apologized after she questioned her. But she says the jogger has left something behind on her runs at least once a week for the past seven weeks.

Police have asked Budde to take pictures of the woman so they can try to identify her. Budde has put up a sign asking the woman to stop. She says there are public restrooms in the area.

Police Sgt. Johnathan Sharketti calls the case “uncharted territory.”
