The Michigan appeals court is hearing the case of a young Detroit man who says he falsely confessed to killing four people when he was 14.
Davontae Sanford's case has been in courts for years. It has an extraordinary wrinkle: A Detroit hit man, Vincent Smothers, told police that he committed the murders, not Sanford. He's willing to testify on Sanford's behalf.
Sanford's attorney is asking the appeals court Tuesday to allow him to withdraw his guilty plea to second-degree murder or at least allow Smothers to testify.
Prosecutors are sticking by Sanford's conviction, although his attorney says he confessed to killing four people at a Detroit drug house in 2007 only to satisfy police.
Meanwhile, Smothers is in prison for eight murders.
