Barbara's murder are unknown although investigators determined that an individual with the name "William Henry Redmond" was working for a railroad in New Mexico at the time of her murder. Her murder is still unsolved. Maria Elizabeth Ridulph 7-year-old Maria Elizabeth Ridulph (born March 12, 1950) disappeared from Sycamore, Illinois on the evening of December 3, 1957. Her remains were found almost five months later in a wooded area near Woodbine, Illinois, approximately 90 miles from her home. Maria was last seen by a friend on the corner of Center Cross Street and Archie Place in her neighbourhood with an unidentified male in his early twenties who went by the name "Johnny." In September 2012, Jack McCullough, formerly known as John Tessier, was found guilty of killing the Ridulph family's neighbour. The DeKalb County State's Attorney stated in March 2016 that a post-conviction analysis of the available evidence revealed McCullough could not have been present at the scene and at the time Maria Ridulph was most likely abducted. On April 15, 2016, McCullough was freed from prison, and on April 22, 2016, the accusations against him were dropped. The DeKalb County Circuit Court found McCullough not guilty of the felony on April 12, 2017. In 1997, Sycamore Police Lieutenant Patrick Solar closed the Ridulph case, naming Redmond as the man who had likely abducted and killed Ridulph. Solar claimed that Redmond admitted to a fellow prisoner that he had committed a crime resembling the kidnapping and murder of Ridulph. Redmond's demeanour and actions, in Solar's opinion, were similar to "Johnny." Redmond, according to Solar, frequently travelled close to the location where Ridulph was discovered when he was employed as a truck driver in the neighbourhood at the time. The research by Solar received criticism for its lack of supporting data and purported political undertones. Redmond would have been difficult to convict in the Ridulph case if he had survived, according to Solar himself, who conceded that the evidence against him was purely circumstantial. Because of this, Solar declared the Ridulph case to be "closed, but not solved," leaving open the chance that a more suitable suspect could be identified in the future. The trial judge disallowed any testimony about Redmond because he was deemed to have not been a plausible suspect when Jack McCullough was later prosecuted in the Ridulph case. Ridulph's murder remains unsolved and her killer unidentified. Jillian
