Here's the new twist. A judge has ordered the Illinois Department of Corrections to preserve any boxes it has that belonged to a deceased inmate named Andrew Wilson.

They many include Wilson's sworn statement implicating himself in the murder, and stating Logan didn't do it. Harold Winston is Logan's attorney. He says he's counting on the Illinois Attorney General's office to get to the bottom of Logan's case.

WINSTON: It is my hope that as this evidence continues to accumulate, they will agree with me that Alton Logan's conviction was wrongful, and actions should be taken as soon as possible to get him out of prison.

The court first learned last week that the statement might exist.

In the past few months, three attorneys have testified that they've had information since 1982 that Wilson—not Logan—committed the murder.
