I believe there was some discussion in telecom-digest about what turns out to be this case.
An Illinois prosecutor announced Friday that... Jack McCullough
> could not have abducted and killed a 7-year-old girl in Northern
> Illinois in 1957, a crime that sent him to prison for life in
> 2012....
> New evidence included recently subpoenaed phone records proving
> that McCullough made a collect call to his parents from a phone
> booth in the city of Rockford, about 35 miles from Sycamore, just
> minutes after the abduction took place - which had always been
> McCullough's professed alibi, but it had previously come under
> doubt.
