SYCAMORE, Ill. (AP) - Cold-case experts say they rarely see arrests in murders that date back so many years.
Authorities in Illinois are hoping to build a case against a former Washington state police officer in the 1957 slaying of a 7-year-old girl in the northern Illinois farming community of Sycamore.
The suspect, Jack Daniel McCullough, was arrested last month. He says he'd taken a military medical exam in Chicago that day. But an archivist says the Air Force file McCullough claims would exonerate him was destroyed in a 1973 fire at the storage site.
Investigators reopened the case three years ago after McCullough's ex-girlfriend told them she found his unused train ticket to Chicago.
Maria Ridulph's abduction grabbed the nation's attention, and her body was later found badly decomposed.
