Illinois State Police say they have a new suspect in the 1957 murder of Sycamore schoolgirl Maria Ridulph.
The case was reopened after police were asked to investigate a suspect named in an anonymous letter. The letter was received March 24, the same day DeKalb State’s Attorney Richard Schmack disavowed the prosecution of Jack McCullough, who was convicted of the murder in September 2012.
McCullough's conviction was vacated after new evidence showed he was in Rockford at the time of Ridulph's disappearance, and he is now seeking a certificate of innocence.
Court documents confirmed the investigation into a new suspect because of a lawsuit from McCullough’s son-in-law. Police declined to comment on the continuing investigation.
