CHICAGO (AP) -- Drew Peterson's lawyer has mailed the former Chicago-area police officer's appeal of his conviction for killing his third wife.
Attorney Steve Greenberg said the appeal was sent in Monday -- a day before the 3rd District Appellate Court's deadline.
Peterson is serving a 38-year prison sentence after a Will County jury convicted him in 2012 of killing Kathleen Savio. The investigation into her 2004 death was reopened after Peterson's fourth wife, Stacy Peterson, disappeared in 2007.
A copy of the 55-page appeal that Greenberg provided cites, among other things, prosecutors' reliance on hearsay evidence.
Peterson exploded in anger in his final statement when a judge sentenced him last year. He startled courtroom spectators by screaming, "I did not kill Kathleen!"
