The second story from the combined Washington Post/60 Minutes partnership will premiere this Sunday. The investigation, from WaPo reporters Dana Priest, Amy Goldstein and 60's Scott Pelley, uncovers the neglectful conditions and inadequate medical treatment in a U.S. government-run prison system that has caused the deaths of some detainees.

The story is Priest's first as a contributor to 60 Minutes.

The first story, "Evidence of Injustice," was a joint investigation that was recently named the winner of the Sigma Delta Chi Investigative Award. It was broadcast on 60 Minutes Nov. 18, 2007, with a print version appearing in The Washington Post the same day.
