Two North Carolina murder cases, both most famous for their wrongful convictions and for the long prison terms served by those convicted, are examined tonight on Investigation Discovery and on WRAL.

The Investigation Discovery channel will devote tonight's episode of "Cold Blood" to the 1982 murder of Deborah Sykes in Winston-Salem. Darryl Hunt (right) was charged and convicted of the brutal murder in 1984, but Hunt didn't commit the crime. He served nearly 20 years in prison before DNA evidence exonerated him in 2004.

Tonight's episode features interviews with Hunt, a friend of Sykes, Sgt. Chuck Byrom of the Winston-Salem Police Department, attorney Mark Rabil, and former Winston-Salem Journal reporter Phoebe Zerwick.
