Maria Ridulph
Maria Elizabeth Ridulph (March 12, 1950 – c. December 1957) was a seven-year-old girl who disappeared from Sycamore, Illinois, on December 3, 1957. Her remains were found almost five months later in a wooded area near Woodbine, Illinois, approximately 90 miles (140 km) from her home. Maria was last seen by her friend on her neighborhood corner of Center Cross Street and Archie Place with an unknown man in his early twenties who called himself "Johnny". The case, which was well known in the Chicago area, was one of the oldest cold case murders in the United States to be presumably solved. Jack McCullough, who under his former name John Tessier had been a neighbor of the Ridulph family, was convicted for her murder in September 2012.
