(Chicago, IL) -- A convicted killer whose case embroiled journalism students in accusations that they'd paid for witnesses is asking for a new trial. A Cook County judge accepted the amended bid yesterday from Anthony McKinney's attorneys. The new filings omit statements from two men who later said that they'd been paid for their interviews by journalism students at Northwestern University's Medill Innocence Project. Prosecutors have tried to subpoena students' notes and grades. McKinney has spent 30 years in prison for the 1978 murder of a security guard that he insists he didn't commit.
