New Trial Ordered for Ex-Cop in Katrina Shooting A federal appeals court has ordered a new trial for a former New Orleans police officer who was convicted of manslaughter for fatally shooting a man whose burned body turned up after Hurricane Katrina. A three-judge panel of the 5th U.S. Circuit Court of Appeals on Monday threw out David Warren's 2010 convictions, saying a judge should have separated his trial from that of four other officers charged in the September 2005 death of 31-year-old Henry Glover. The judges agreed with Warren's argument that the "spillover effect" from other evidence unrelated to the shooting, including the burning of Glover's body, prevented Warren from getting a fair trial. Warren was sentenced to more than 25 years in prison for shooting Glover outside a police substation at a strip mall.
