MADISON (AP) -- A lifelong con man imprisoned in Wisconsin worked with associates outside the walls to operate a suspected diploma mill until authorities uncovered the scheme.
Interviews and documents show 44-year-old Kenneth Shong helped to run "Carlingford University" even while he was behind bars. Prison authorities uncovered the scheme in late 2008, but Carlingford's Web site was taken down only this month after The Associated Press interviewed its designer.
Higher education regulators in Wisconsin and Alabama have sent letters to Carlingford representatives asking them to cease and desist operations, and the Wisconsin Department of Justice has opened a criminal probe.
Records show Shong was put in isolation for 45 days as punishment after prison officials uncovered his role in late 2008 by reading his mail.
