Charles Howard Schmid Jr., also known as the Pied Piper of Tucson, was an American serial killer whose crimes were detailed by journalist Don Moser in an article featured in the March 4, 1966, issue of Life magazine. Schmid's criminal career later formed the basis for "Where Are You Going, Where Have You Been?", a short story by Joyce Carol Oates. In 2008, The Library of America selected Moser's article for inclusion in its two-century retrospective of American true crime literature.
