Henry McCollum

In an an Aug. 12, 2014 photo, Henry McCollum sits on death row at Central Prison in Raleigh, N.C. He and his half brother Leon Brown have spent more than three decades in prison for the rape and murder of 11-year-old Sabrina Buie in 1983. On Tuesday, Sept. 2, 2014, lawyers for Lawyers for 50-year-old McCollum and 46-year-old Brown will ask for their release, saying DNA analysis of a cigarette butt found at the crime scene in Robeson County link it to a man serving a life sentence for a similar rape and killing that took place a month later. The Center for Death Penalty Litigation says that man was the real killer of Sabrina Buie in 1983. (AP Photo/The News & Observer, Travis Long) MANDATORY CREDIT, TV AND TV WEBSITES OUT
