Defense attorneys say there was not enough evidence to send Jack McCullough to prison. McCullough was sentenced in 2012 to life behind bars for the 1957 kidnapping and murder of 7-year-old Maria Ridulph of Sycamore. It was believed to be the nation's oldest cold case.

"We asked for a new trial as well as an alternative remedy here," Glaser said. "We really have to wait and see because what the court is going to do, they act and we react."
