Never throw away anything?

In 1957, a little girl was abducted and killed. The murder mystery has apparently been solved 54 years later.

Police suspected McCullough, who lived less than two blocks from the Ridulphs and who fit the description of the man said to have approached the girls, Thomas said Friday. But McCullough seemed to have an alibi, claiming he took the train from Rockford to Chicago the day of the abduction.

His story fell apart last year after investigators reinterviewed a woman who dated him in 1957 and asked her to search through some personal items, the Seattle Times reported, citing court documents. She found an unused train ticket from Rockford to Chicago dated the day the girl went missing.

"Once his alibi crumbled, we found about a dozen other facts that helped us build our case," Thomas said.
