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. However, in March 2016, the DeKalb County State's Attorney announced that a post-conviction review of available evidence showed McCullough could not have been present at the place and time of Maria Ridulph's likely abduction. McCullough was released from prison on April 15, 2016, and the charges against him were dismissed on April 22, 2016. McCullough was declared innocent of the crime by the DeKalb County Circuit Court on April 12, 2017.
