NEW ORLEANS - A new trial will begin March 11 for a former New Orleans police lieutenant accused of covering up a police killing after Hurricane Katrina. The ex-officer accused of killing the man will be tried a week later.

U.S. District Judge Lance Africk set the dates Tuesday. David Warren is accused of shooting 31-year-old Henry Glover on Sept. 2, 2005. Travis McCabe is accused of doctoring a police report to make it appear that Warren was justified.

Africk ruled in 2011 that McCabe deserves a second trial because an earlier copy of the report he's accused of changing was found after his conviction.

A federal appeals court overturned Warren's conviction in December, saying he should have been tried separately from officers accused of the cover-up. His trial begins March 18.
